MAINTENANCE
GENERAL CARE
1. Turn the rotary selector to OFF position to switch off the power when
the meter is not in use.
2. Remove the batteries to avoid damage to the meter if it will remain
unused for a long time.
3. Do not attempt to remove the rear case to adjust or repair the meter.
Repairs should only be performed by a qualified technician.
4. Use a damp cloth and mild detergent to clean the meter. Do not use
abrasives or solvents.
BATTERY REPLACEMENT
The batteries required are 3 x 1.5V AAA.
1. Disconnect the test leads from sources of electric current before
opening battery cover. Loosen the fixing screw on the battery cover
and remove it.
2. Replace the exhausted batteries with new ones. Take care that the
polarity of the batteries are correct, as marked on the inside of the
housing.
3. Put the battery cover back and secure with the fixing screw.
4. Dispose of your old batteries in accordance with local regulations.
REPLACING THE TEST LEADS
The replacement leads must be in good condition with the same rating as
the originals i.e. 1000V, 10 A.
A test lead must be replaced if the insulation layer has been damaged.
CALIBRATION
Calibration should be carried out once a year at a temperature between
18°C and 28°C (64°F to 82°F) and relative humidity below 75%.
