Analog Output; Battery Charging; Computer Interface - THORLABS PM100D Quick Reference

3.2.4 Analog Output

The analog output provides the amplified photo-diode current or the amplified
thermal or pyroelectric sensor voltage.
The signals from the analog outputs are not wavelength and zero corrected. The
analog output voltage is range dependent and can be calculated to:
U = 2V / full scale range value x measurement value
Analog Out
The analog output voltage can range from -0.3V to +2.3V.

3.2.5 Battery Charging

+
The PM100D is powered by a 1 cell LiPo battery that needs to be recharged
intermittently by plugging the AC adapter or plugging the USB cable to a
computer. To fully charge the battery it takes approximately 3-4 hours. A built in
charging circuit automatically regulates and terminates the charging.
Following battery icons in the display header show the charging state from empty
to full battery
The empty battery symbol starts blinking for one minute until the unit shuts off.
When an external power supply is plugged the symbols above change sequent
until the battery is fully charged.

3.3 Computer Interface

The PM100D optical power meter contains a USB 2.0 interface. When connecting
the PM100D to the PC first time, a new hardware will be found. For proper
installing the PM100D it requires a NI-VISA runtime version on the PC (available
on the National Instruments website www.ni.com) or from the data carrier that
comes with the instrument. Allow installing and follow the dialog instructions.
The PM100D comes with a utility software that easily enables remotely operating
the PM100D (also PM100A and PM100USB) and visualizing and logging
measurement data. Perform the setup.exe and follow the installing instructions.
The LabVIEW source code of this application is included on the data carrier as well
and can be used to build own applications or to modify the utility program to
specific requirements (LabVIEW 8.5.1 or higher required).
