Service 5.1

This section contains Calibration , Test and Trouble-shooting procedures that can be per-
formed by the user. Instruments are calibrated to its input type at the factory prior to ship-
ment. Re-calibration should not be necessary under normal operating conditions.

Calibration 5.2

Caution: Do not attempt any of these calibrations without the proper test equipment with specifications
equal to or better than those listed.

Press and release the SCROLL key to sequence the display until CAL appears. If CAL does
not appear, refer to Section 3 for instructions on how to enable the Calibration mode. When
CAL appears on the display, press the DOWN key. The display will read CAL 1. CAL 1

can

be initiated at this time or press the SCROLL key to advance the display to the other calibra-
tions available.
