Safety Note The design of this meter is accordance with IEC61010 clause (the safety standard issued by International Electro technical Commission). Prior to the operation of the instrument, please read the safety considerations before use. 1. When DC voltage above 30V, AC voltage above 25V, current above 10mA, AC power line with inductive load or power line during electric fluctuation is measured, please beware of electric shock.

8. It may damage to the meter and endanger the operator’s safety if the voltage value beyond the permitted ultimate voltage value is measured. The ultimate voltage value permitted for measurement is marked on the instrument panel; and never measure the value exceeding the standard. Don’t input the ultimate value out of regulation in order to avoid electric shock and the damage to the meter.
Instrument Panel & Function Button Description 1. Instrument model number 2. LCD Display: Display the measured data and unit. 3. Function Button 3.1 Hz/% (Frequency / Duty Cycle): Press this button to select the frequency or duty cycle mode. The measurement mode of voltage / frequency / duty cycle could be selected by pressing this button in AC voltage or Hz...
Other Functions Auto Power off During measurement, the meter will automatically shut down (enter sleeping mode) to save power if function buttons and knob switch are not operated in 15 minutes. In auto power off mode, press any function buttons or rotate the knob switch, the instrument will get into the auto power on mode (working mode) Property General Feature...
