safeguards within this equipment.
1. Automatic Selection
Insert the red test lead to the “V/OHM” jack, and the black test lead to the “COM” jack.
When turned on, the DMM powers up in SCAN mode.”SCAn” will appear in the LCD. Test the object by 2 test
leads, you’ll get the tested AC, DC voltages or resistance.
The DMM automatically selects the appropriate measurement mode and range.
Without exterior voltage, the DMM shifts to resistance measure mode to measure it when the resistance in the
input terminals is below 40Mohm.
Input DC voltage b0.7V and +600V on the input terminals, or between -0.12V and -600V, or even AC
voltage between 3V and 600V (frequency between 40 Hz and 400Hz), then the DMM enters the corresponding
measure mode for DC voltage or AC voltage.
In DC and AC voltage modes, the DMM has high input impedance
(10M
Ω
).
If the test leads are disconnected from the “V/OHM” jack and then connected to the “A” jack, it can be used as
a current meter. DMM enters its current measure mode automatically when the flowing current exceeds the
limited value(5mA).
