Maintenance
This meter is precise device, Do not attempt to repair or service your meter you are qualified to do so
andhavethe relevantcalibration performance test, andserviceinformation.These products are intelligent
meter, use self-calibrating technology. To avoid the specification error. All components not replaced
except that if is specified.
General Maintenance
Periodically wipe case with a damp cloth mild detergent.Do not use abrasives or solvents.Dirt or moisture
in the terminals can affects readings.To clean the terminals.
1. Turn the meter OFF and remove all test leads.
2. Clean out any dirt that may be in the terminal.
3. Soak a new swap with a cleaning and oiling agent.
4. Work the swab around in each terminal the oiling agent insulates the terminals from moisture
Related contamination.
Battery Replacement
Waring
To avoid electrical or are blast, or personal Injury or damage to the meter, use specified fuses
ONLY in accordance with the following procedure
The meter is powered by a 9V battery (NEDA 1604, 6F22, 006P), Replace battery if the low battery sign
“ ” displayed. Use the following procedures to replace the battery.
1. Set the rotary switch to “OFF” position.
2. Pull up test leads from terminals.
3. Loosen the screw on battery case, pull up and moce the case.
4. Replace the defective battery.
5. Reverse the procedure of opening to close the battery case.
Fuse Replacement
Waring
To avoid electrical shock or personal injury, remove the test leads and any input signals before
replacingthe Fuses.To preventdamages or injury,install ONLY replacement fuseswith the ampere,
voltage, and speed ratings specified.
1. Perform steps 1.2.35. of battery replacement procedure
2. Install new fuse of some size and rating.
