MAINTENANCE
Do not attempt to repair this meter. It contains no
user-serviceable parts. Repair or serving should only be
performed by qualified personnel.
1. Inspect the jaw mating surface for cleanliness. If any
foreign material is present, the jaw will not close properly
and measurement errors will result.
2. Verify that the range on the meter is correct.
Calibration Interval
We suggest a calibration interval of one year. If the instrument is
rarely used, the calibration interval can be extended to 3 years.
Cleaning
To avoid damaging the meter, do not use abrasives or
solvents to clean it.
Always keep the metal parts of the jaw clean and dry. Avoid
allowing dust or other particles to come in-between the jaws.
Remove and clean these parts carefully by soft air pressure.
Also ensure that there is no rust or oxidation on the metal
surfaces. In case of contamination (dust or oxidation) the
commutator segments of the jaw could be damaged or
bent. In this case, the current clamp will be damaged and
outside specification. Please send the current clamp to
service for repair.
BATTERY REPLACEMENT
1. Disconnect the jaw from measuring circuit.
2. Turn the meter OFF.
3. Remove the screws from the battery cover and open the
battery cover.
4. Remove the batteries and replace with 2 1.5V AAA
size (IEC R03) batteries. Observe correct polarity when
installing the batteries.
5. Replace the battery cover and re-fasten the screw.
