�Automatic measurement
Note
●Do not measure any voltage higher than 1000V DC/1000V AC to prevent
electric shock or damage to the instrument.
●Do not apply more than 1000V DC voltage/1000V AC voltage between the
common terminal and the ground to avoid electric shock or damage to the
instrument.
In automatic mode, AC and DC voltage, resistance and continuity can be automati-
cally measured.
1. After power on, it will automatically switch to "AUTO" automatic measurement
mode.
2. Connect the black test lead and the red test lead to the COM input jack and the
INPUT input jack respectively.
3. Use the test pen to measure the voltage value, resistance value and short-circuit
point of the circuit to be tested at both ends. (parallel to the circuit under test)
4. At this time, the liquid crystal display will display the corresponding measured
voltage value and resistance value at the same time. When measuring DC voltage,
the display will show the voltage polarity connected to the red test lead at the
same time. If the measured resistance value is less than 50Ω, the buzzer will issue
an alarm sound.
1. When measuring low resistance, in order to measure accurately, please first
short-circuit the two test leads to read the short-circuit resistance value of the
test leads, and subtract the resistance value after measuring the measured
resistance.
Notice
When the measured DC voltage is less than 0.75V and the AC voltage is less
than 0.75V, the displayed resistance value may appear, because the
minimum measurement voltage value of this product is 0.75V, and the
minimum AC voltage is 0.75V.
