Checks for Obvious Problems
When first troubleshooting the Instrument, check for obvious problems by answering basic
questions such as the following:
1 Is the power switch turned on?
2 Is the battery adequately charged?
3 If running from mains power supply, is the AC power cord connected to the Instrument
and plugged into an AC outlet?
4 Are the Measurement Server and, if present, the Measurement Server Extension inserted
correctly?
Checks Before Opening the Instrument
You can isolate many problems by observing indicators on the Instrument before it is
necessary to open the Instrument.
Checks with the Instrument switched Off

• Battery LED is on (green if fully loaded, yellow if being charged).
• Battery LED red and blinking signals battery malfunction.

NOTE It takes several seconds for the AC Power LED to switch on / off after the mains power cord
has been connected / disconnected.
