Above accuracies can be guaranteed within 5%~100% of the full range.
The true RMS meter has residual value within 10 counts when the test leads are shorten, but that
will not affect the accuracy of measurement.
1. Frequency Range for ACA: 40Hz-400Hz
2. Overload protection: F 10A/1000V fuse for 10A
Overload protection: F 0.63A/1000V fuse for µA and mA ranges.
3. Maximum input current: 600mA DC or 600mA AC rms for µA and mA ranges, 10A DC or 10A AC
rms for 10A ranges.
4. For measurements>6A, 15 seconds ON each 10 minutes; Above 10A unspecified.

5. MAINTENANCE

This section provides basic maintenance information, including fuse and battery replacement
instructions.
Do not attempt to repair or service your Meter unless you are qualified to do so and have the
relevant calibration, performance test, and service information.

General Maintenance

To avoid electrical shock or damage to the meter, do not get water inside the case.
Remove the test leads and any input signals before opening the case.
Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents.
Dirt or moisture in the terminals can affect readings.
To clean the terminals:
Turn the meter off and remove all test leads.
Shake out any dirt that may be in the terminals.
Soak a new swab with a cleaning and oiling agent (such as WD-40).
Work the swab around in each terminal. The oiling agent insulates the terminals from moisture-
related contamination.
