CALIBRATION
It is recommended that the multimeter be calibrated once each year and/
or after it is repaired. Perform calibration at 75±5
O
F and a relative humidity
of 70% or less.
1. Allow multimeter to stabilize for at least thirty minutes.
2. Remove back cover.
3. Select the 200mV DC range on the meter. Set the output of
the DC calibrator for 1.900V±0.02% and connect it to the V-W
and COM input connectors.
4. Use a small flat-tipped screw driver to adjust the pot located
below the MAX HOLD button (VR2 position--the only adjust-
able pot on the board) to obtain a reading of 190.0 in the
digital display.
5. Disconnect the DC calibrator from the multimeter and replace
the back cover.
Cleaning
The instrument can be cleaned with a soft clean cloth to remove any oil,
grease or grime from the exterior of the meter. Never use liquid solvents or
detergents. If the instrument gets wet for any reason, dry the instrument
using low pressure "clean" air at less than 25 PSI. Use care and caution
around the LCD display protector and areas where water or air could enter
the interior of the instrument while drying.
