value will not exist any more. It begins at 0V to measure the voltage range.
DC and AC Current measurement
Refer to Automatic Selection.
When the current is above 5mA, the DMM enters current measure mode automatically. The LCD will indicate the
current with DC or AC and its shown with figures in the corresponding units A or mA
Warning
To avoid damage to the meter or injury if the fuse blows, never attempt an in-circuit current measurement where
the open-circuit potential to earth is greater than 250V. To avoid damage to the meter, check the meter’s fuses
before proceeding. Never place the probes in parallel with a circuit or component when the leads are plugged into
the current terminals.
2. Button Definition
Due to the fact this meter only contains 3 buttons, usually SELECT, MAX/MIN and HOLD are chosen to be set.. If
necessary, such keys as MAX/MIN can be shifted to others like Hz/DUTY.
