Clean the front panel and case with a mild solution of detergent and a damp sponge. Clean dust
from the PWB with clean, dry, low pressure (<20 psi).
Calibration Procedure
The Calibration Procedure should be performed annually and any time your instrument has
been repaired. The calibration procedure consists of two parts:
1)
The Voltage Calibration adjustment calibrates the voltage output to agree with the meter
reading.
2) Leakage Current calibration adjustment calibrates the internal current meter to obtain the
real current flowing between the two points of test.
NOTE
Allow the instrument to stabilize for approximately five minutes. Perform all calibration
adjustments at an ambient temperature of 23
°
C
±

C (73

WARNING
CALIBRATION ADJUSTMENTS ARE PERFORMED ON ENERGIZED CIRCUITS.
EXERCISE CAUTION AT ALL TIMES, AND USE A NON-CONDUCTIVE TOOL FOR
ALL ADJUSTMENTS.
