Maintenance:
a. Except for battery, there are no user-serviceable parts inside the
PL200G Data Logger.
b. Global Water recommends checking the batteries every 6 months.
XVI. Troubleshooting:
Issue: Logger is reading incorrectly.
a. Verify the battery supply has enough voltage. To operate properly, the
logger must have an absolute minimum of 10 volts for the sensor to
operate. If the battery voltage monitor is reading less than 15 volts or
seems incorrect, check the batteries with a voltmeter or replace them.
Battery voltages of less than 15 volts indicate that the batteries need
replacing.
b. Check the logger and sensor calibration numbers in the Setup Menu.
Recalibrate the logger if necessary. As a precaution, save the setup
file first as described in section XI.
Issue: Cannot communicate with the logger.
a. Verify that fresh batteries are installed.
b. Check the communication cable.
c. Use the Device Manager to confirm that the driver is loaded and the
correct virtual COM port is selected in the connection menu of the
Global Logger software. Check the Device Manager in your operating
system and confirm that the USB COM port is not being used by
another device.
d. Try reducing the baud rate in the connection screen of the Global
Logger software.
