Resistance measurement
Refer to Automatic Selection.
Without exterior voltage, the DMM shifts to resistance measure mode when the resistance in the input terminal is
below 40MΩ.
The tested resistance will be shown with figures, accompanying corresponding units Ω
，
kΩ or MΩ. In resistance
measure mode, do not impose voltage on the test resistance or it may be damaged or operated incorrectly.
DC and AC Voltage measurement
Refer to Automatic Selection. When the Volts DC is above +0.7V or -0.12V, Volts AC is above 3Vrms, the DMM enters
volt measure mode automatically. The LCD will indicate the voltage with DC or AC and its shown with figures in the
corresponding units V or mV.
Change the test leads for the contacting point of the tested circuit if you want to test the DC voltage below 0.7V, you
can get the voltage of as low as 0.12V.
Warning
When AC and DC voltage are simultaneously contained, the DMM will only show the voltage which has larger
virtual value (DC or AC)
Continuously press SELECT key to the stable status of measuring DC or AC voltage, the above valve
