Warning

BE EXTREMELY CAREFUL WHEN USING THIS METER. Improper use of this device can result in electric shock or destruction of the meter. Take all normal safety precautions and follow the safeguards suggested in this manual.

To exploit full functionality of the meter and ensure safe operation, please read carefully and follow the directions in this manual.

PRELIMINARY

Follow all safety and operating instructions to ensure safe use of the meter:

- General protection against electric shock

- Protection of the meter against misuse

When the meter is delivered, check whether it has been damaged in transit.

After being stored and delivered under harsh conditions, the meter should be checked and confirmed whether any damages have been incurred.

Test leads must be kept in good condition. Before using check whether the insulation on test leads has been damaged and any wire has been exposed.

Use the test leads supplied to ensure operation safety. If required, they must be replaced with test leads of the same model or class.

Technical specifications:

Environment temperature:235℃ Relative humidity:<75%
3.2.1 True RMS
3.2.1.1 For measuring non-sinusoidal waveforms, test error which is occurred by using True RMS measurement techniques is less than by using traditional average-reading techniques.
3.2.1.2 Both sinusoidal and non-sinusoidal waveforms can be tested by True RMS Clamp Meter exactly. At AC A & AC V ranges, even short two test probes there are still 1-50 digits might be displayed on LCD. This is normal. Test result will not be affected.
3.2.1.3 At AC A and AC V range, True RMS value can be tested only when input signal is more than 2% -100%of full range.
3.2.2 AC Current

- maximum/ input current:100A AC

- Frequency range:50Hz

3.2.3 DC CURRENT(2008D)

- maximum/ input current:100A DC

3.2.4 DC Voltage

- Input impedance:10MW

- Maximum/ input voltage:600V AC (Effective value)OR 600V DC

NOTICE:

At small voltage range, unsteady readings will appear before the test leads contact the circuit. This is normal because the meter is highly sensitive. When the test leads contact the circuit, the true reading will be shown.
