Troubleshooting
Before troubleshooting or repairing the instrument, make sure the failure is in the instrument rather than
any external connections. Also make sure that the instrument was accurately calibrated within the last
year (see
Calibration
Interval). The instrument's circuits allow troubleshooting and repair with basic test
equipment.
DO NOT swap the motherboard or the front panel board from one instrument to another. These
boards contain model number and serial number information that uniquely identifies a specific
unit, and boards that are mismatched to the instrument may result in problems with its per-
formance, licensing, serviceability, importability/exportability or warranty.
