  
Before using the Meter, inspect the case. Do not use the Meter if it is damaged or the case (or part of the case) is removed. Look for cracks or missing plastic. Pay attention to the insulation around the connectors. Inspect the test leads for damaged insulation or exposed metal. Replace damaged test leads with identical model number or electrical specifications before using the Meter. Do not apply more than the rated voltage, as marked on the Meter. When your measurements have been completed, disconnect the connection between the test leads and the circuit under test, remove the test leads from the input terminals of the Meter and turn the Meter power off. Do not carry out the measurement when the Meter’s back case and / or battery door is opened to avoid electric shock. When the Meter is operating at an effective voltage over 30V in AC, special care should be taken. Use the proper terminals and function for your measurements. Do not use or store the Meter in an environment of high temperature, humidity, explosive, flammable and strong magnetic field. The performance of the Meter may deteriorate if damp or wet. Do not use the Meter if its surface is wet or the user’s hands are wet. When using the test leads, keep your fingers behind the finger guards. Replace the battery as soon as the battery indicator appears. With a low battery, the Meter might produce false readings that can lead to electric shock and personal injury.
Warning
Rules For Safe Operation
To avoid possible electric shock or personal injury, and to avoid possible damage to the Meter or to the equipment under test, adhere to the following rules:

  
When opening the battery door, make sure the Meter is off. When servicing the Meter, use only the same model number or identical electrical specifications replacement parts. Do not tamper with the internal circuits of the Meter. Soft cloth and mild detergent should be used to clean the surface of the Meter when servicing. No abrasive and solvent should be used to protect the surface of the Meter from corrosion, damage and accident. The Meter is suitable for indoor use only. Turn the Meter off when it is not in use and take out the battery when not using for a long time. Periodically check the battery as it may leak when it has not been in use for some time, replace the battery if the battery is dead or leaking. A leaking battery will damage the Meter.

True RMS Measurement and Average Value Measurement
The True RMS measurement method can measure accurately the effective value of non-sine wave input signal. Average value measurement method can measure the mean value of one sine wave input signal, and then displays it as RMS value
Note
When there is no input signal, it cannot carry out active energy measurement. When there is input signal, the maximum waiting time is approximately 10s before timing. When testing has been completed, disconnect the connection between the testing leads and the circuit under test and remove testing leads from the input terminals.
5. MAX/ and MIN/ are not valid when measuring active energy.
6. Press CLEAR to reset the time.
The maximum reading of acitve energy is 9999kWh. OL will be displayed when the reading is over than that.
When the input waveform has distortion, measuring tolerance will be included. The total tolerance depends on the total distortion. Below table 1 shows the waveform coefficient and the relationship and the requested changing factor of sine wave, square wave, peak wave of triangle wave, RMS value and average value.

72-9490: OPERATING MANUAL
To clean the terminals, wipe with cotton or lint free cloth and mild detergent. Dirt or moisture on the terminals may affect readings.
Remove the battery when not in use for an extended period of time.
MAINTENANCE
This section provides basic maintenance information including battery replacement instruction.
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.
To avoid electrical shock or damage to the Meter, do not get water inside the case.
Warning
A. General Service
Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents.
Turn the Meter off when not in use.
Do not store the Meter in places of high temperature, humidity, explosive/flammable environments, or in a strong magnetic field.

Figure 24
B. Replacing the Battery (see figure 24)
To avoid false readings, which could lead to possible electric shock or personal injury, replace the battery as soon as the battery indicator “
” appears.
Make sure the transformer jaw and the tests leads are disconnected from the circuit being tested before opening the case bottom.
Warning
To replace the battery:
1.
2.
