Browsing Tracker Charts

SFx Asset management helps you monitor the working conditions of most critical tracker sensors as well as sensor- and field checks in graphical formats.

There are 6 aspects of metrics in the tab list.

LT_ChartDropdownicons_0701.PNG

This chart displays the environmental changes over time detected by various sensors: temperature sensors, pressure sensors, and humidity sensors. By default, the last 24 hours of data points (1D view) will be displayed in the line chart.

On the left, the Air Temperature chart is displayed by default. The horizontal axis is the time span that is adjustable, and the vertical axis is the temperature value. Three indicators at the top of the chart show the sources of temperature data, including Internal, External, and Manual Reading. See Meteo Station Status for details.

  • The temperature curve with a light-green background indicates the segment of temperature data is read from external air sensors;

  • The temperature curve with a light-blue background indicates the segment of temperature data comes from manually entered reading;

  • The temperature curve without background indicates the segment of temperature data is read from internal sensors.

Two red dash lines are pre-defined as the normal working range (0℃-40℃) for temperature sensors. When the temperature value exceeds the range, then the dot is marked as Not OK in red. Otherwise, it is marked as OK in green. Hover your cursor over any point of the curve, you can read the precise value of the point.

To switch to the 1-Week view or 1-Month view, click the Date selection icon at the upper right corner. See the figure below for the 1W view.

Data points more than one day will be displayed in bar charts with three values:

  • Max Temp — The maximum temperature value monitored during a day.

  • Min Temp — The minimum temperature value monitored during a day.

  • Ave Temp — The average temperature value monitored during a day. It is calculated by the average value of all the data points captured in a day.

Each bar chart indicates the aggregated temperature values monitored during a day, including Max, Min, and Avg values. Similarly, when a value is located in the tolerable area rendered in green background, it will be marked green; otherwise, it will be marked red, which means the result is out of tolerance.

Hovering over any bar in the chart, you can read the accurate temperature values on that day, including Max temp, Min temp, and Avg temp values.

Tip

  • You can also specify a time range of up to 30 days to check the Meteo station changes from the CUSTOM view.

  • To switch to other charts, click on the dropdown menu lower than Meteo Station and select a desired item from the list.

  • Click on the image4.png icon to download each of the charts as an image in .png format.

On the right is an overview of the Meteo Station. The table below illustrates each property marked up with numeric labels.

The time of the last read (unit: YYYY-MM-DD HH:MM:SS).

The Drift Monitoring chart displays a tracker’s drift changes over time detected by leveling sensors when the monitoring is turned on. By default, the last 24 hours of data points (1D view) will be displayed in the line chart.

image11.png

On the left is the drift monitoring chart indicating the drift value of a tracker on the X-axis and Y-axis over time, along with the OTG (Orient to Gravity) events. The horizontal axis is the adjustable time span within 24 hours by default, and the vertical axis is the detailed drift value.

While hovering over any point of the curve, you can read the accurate drift values and evaluation results at the time point. When the drift value is located in the range of the pre-defined tolerable area rendered in green background, for instance, -0.2~+0.2 mm/m, the evaluation result shows OK; otherwise, it shows NOT OK, which means the result is out of tolerance. The yellow dash line paralleled with the vertical axis indicates an OTG is performing at that time.

Tip

The OTG function enables you to measure with the Z-axis aligned to gravity for leveling and alignment tasks.

To switch to the 1-week view or 1-month view, click the Date Selection icon at the upper right corner. See the figure for the 1M view below.

Data points for more than one day will be displayed in bar charts with three values:

  • Max Drift — The maximum drift value (X-axis or Y-axis Drift) during a day.

  • Min Drift — The minimum drift value (X-axis or Y-axis Drift) during a day.

  • Ave Drift — The average drift value (X-axis or Y-axis Drift) during a day. It is calculated by the average value of all the data points captured in a day.

Tip

When you zoom on the X-axis either by scrolling the mouse wheel forward or the Zoom-by-drag button, the scaling in the Y-axis is also adjusted automatically. It helps you read tiny changes, especially when many data points are gathered in a small area.

The blue bar in the chart indicates the X-axis drift and the yellow bar indicates the Y-axis drift. Similarly, when a value is located in the tolerable area rendered in green background, it will be marked green; otherwise, it will be marked red, which means the result is out of tolerance.

Hovering over any bar in the chart, you can read the accurate values of the X-axis and Y-axis drift on that day, including Max drift, Min drift, and Avg drift values.

You can also specify a time range of up to 30 days to check the drift changes from the CUSTOM view.

The pane on the right denotes the summary status of monitoring and leveling sensors with the drift values checked last time. See Drift Monitoring Status for details.

Note

When the monitoring is turned Off, a blank chart will be shown.

This chart displays the power supply level of the main power using AC power and the power usage of external batteries connected to a laser tracker over time.

image13.png

On the left is the chart of power usage trending over time. The horizontal axis is the time span which is adjustable by dragging the solid blue dots, and the vertical axis is the remaining battery power value represented by percentage.

On the right is a summary of the current power configuration with the currently remaining power level of each power source.

At the bottom is the last updated time of the power supply data (unit: YYYY:MM:DD HH:MM:SS). See Power Supply Status for details.

This chart visually displays sleep schedules defined in Tracker Pilot to turn the laser ON or OFF automatically in accordance with the scheduled timers.

image14.png

On the left is the calendar-style chart of schedules available on a weekly basis. The horizontal axis is the day of the week and the vertical axis is the timetable within 24 hours. Each preset schedule is displayed in a time slot while the Active Schedule is green and Sleep Schedule is blue. The duration of each schedule is clearly shown at the top of its time slot. Additionally, a white dashed line in parallel with the horizontal axis indicates the current time while the current date is highlighted in blue across the intersection of the white dot.

Note

When you and your laser tracker are not in the same timezone, for example, you are monitoring a laser tracker located in a factory in Munich, Germany from an office in Beijing, China, this chart displays scheduled date and time based on the timezone where the asset is serving (i.e. UTC +02:00) to keep consistent with Tracker Pilot.

You can click on the Today button on the top right to switch to a daily view of the preset schedules. Also, the entire schedule chart can be downloaded as an image by clicking on the image4.png icon.

Note

This Sleep Schedule mode is applied to turn On or Off the laser automatically according to scheduled timers unlike the schedules set for other assets in the Production Schedules menu which indicate the predefined production time or downtime for specified assets and correlate with OEE metrics.Schedule Management

On the right is an overview of the laser schedule mode, including the current laser state (in active or sleep mode), the next sleep scheduled or next active time, and the last updated time (unit: YYYY-MM-DD HH:MM:SS).

Note

The last updated time is displayed based on the timezone (as indicated in the figure above, UTC +08:00) where the SFx account is logged in while the Next Sleep Scheduled time or Next Active time is displayed according to the tracker timezone.

There are two categories of system checks you can perform with a tracker within Tracker Pilot software:

  • Sensor Checks — A sensor check is applied to test if the manufacturer’s specifications comply with the parameters of the current active Absolute Tracker. A sensor check is a guided process and it requires system settings are preset in a tracker.

  • Field Checks — A field check is used to check which accuracy can be achieved under the current environmental conditions with desired settings of a user-specific workflow.

Results of several sensor checks are visualized, including

  • Axes Check

  • ADM Offset Check

  • Probe Check (only for AT960 model)

  • Scan Axes Check (only for ATS600 model)

You can select a desired check from the drop-down list to view the corresponding chart.

image15.png

The curve is shown at the position of the last performed check every time you open the Sensor Checks chart (see the green dot that is relatively bigger than the others). The horizontal axis is the adjustable time span within 24 hours by default, and the vertical axis is the Tolerance Used value (unit: %).

Each check result is shown as a colored dot spreading around a fixed line, called Acceptance Level, which can be specified manually in the Tracker Pilot based on the current environment. Dots under the line get marked as green, indicating the check result is within the tolerance while dots above the line are marked as red, which indicates the check result is out of tolerance and should be adjusted.

The line in solid blue is called the Trend line, which reflects the general tendency of the selected check results.

Tip

  • Click on any dot in the chart to view the details of the check result on the right pane.

  • While hovering over a dot, you can read the accurate value of the dot.

  • Click the image4.png icon to download the chart as an image.

A history of sensor checks performed is stored in the Tracker Pilot. After completing all Sensor Checks, the operator has the option to transform the performed checks into compensation, to adjust the checked system parameters especially when the check result is NOT OK.

The table below describes each property that presents in the check details pane.

To guarantee the measurement accuracy of a tracker in different environments and applications, the operator usually performs a set of Field Checks with a specific target to get the Tolerance Used values for the current environment based on a customizable Acceptance Level before implementing the measurement tasks.

There are 3 different Field Checks available for now:

  • Two Face Check

  • Scale bar Check

  • Tip Check

LT_FieldChecksChart_WithLastPerformedCheck.PNG

You can select a desired field check from the drop-down list to view the corresponding chart.

Unlike the Sensor Checks, each check result for the Field Check is shown as a separate colored dot scattering around a fixed line, called Acceptance Level, which can be specified manually in Tracker Pilot based on the current environment.

Similarly, the chart is shown at the position of the last performed check every time you open the Field Checks chart (see the green dot that is relatively bigger than the others). You can click on any dot in the chart to view the details of the check result on the right pane.

Click the image4.png icon to download the chart as an image.

Especially, after performing a Tip Check, you can find the tip and probe that are being used for the check by these three properties displayed on the right details pane:

  • Probe Type

  • Probe Serial Number

  • Tip Serial Number

In addition, when a Probe is used as the target in a Two Face Check, you can find the probe type and its serial number on the right details pane as well.
