Needle View; Graph And Statistics Display - THORLABS PM200 Quick Reference

PM200
Delta Reference is the reference power value, when the console measures the
deviation (Delta measurement)
Actual is the measured value. This display is useful when performing Delta
measurements - in this mode the main display shows the deviation from the delta
reference value, so in a subpanel the actual power can be displayed.
Sensor temperature: Most of Thorlabs photodiode and thermal sensors are
equipped with a NTC Thermistor to control the temperature of the sensor head.
To show the sensor temperature, pick the "Sensor Temperature" subpanel and
drop it to the main view.

3.5.2 Needle View

In contrast to the numeric view, the needle view offers additionally a needle
gauge with min and max indicators. Subpanels are not available.

3.5.3 Graph and Statistics Display

For recording, visualizing and analyzing the measurement data in Watts or Joules
over time, the PM200 features a scope view and a statistics analysis with a
histogram view. During the record, the data will be stored to an internal temporary
file. After the record is finished or has been stopped, the measurement data can
be permanently stored to the internal logging drive or the USB drive. The data
format is comma separated (.csv) and contains
measurement value
time stamp
additional settings
sensor information.
The record stopping criteria can be selected to manually, elapsed time or
