G terminal blocks and a 1 foot red wire attached to one of the 12V
terminal blocks. Attach the red wire from the power supply to the datalogger
Power terminal block marked 12V (Campbell Scientific part number 3768).
Attach the black wire from the power supply to the datalogger Power terminal
block marked “G”.

incoming connections are correct and there is an adequate charging voltage
present.
3.5 Turn On Power to the Datalogger
Flip the switch on the PS150/CH150 supply to “On”. Verify voltage to the
datalogger with a volt meter, or use a key pad display, or connect to the
datalogger with a laptop or PDA to make sure the datalogger is running
correctly.
