circuit impedance is less than or equal to 10kΩ, the error is negligible (0.1%
or less).
● When DC/AC voltage measurement has been completed, disconnect the
connection between the testing leads and the circuit under test and remove
testing leads from the input terminals.
B. Measuring Resistance
(see figure 4)
Warning
To avoid damages to the Meter or to the devices under test, disconnect
circuit power and discharge all the high-voltage capacitors before
measuring resistance.
To measure resistance, connect the Meter as follows:
1. Insert the red test lead into the
V
Ω
Hz
terminal and black test lead into the
COM
terminal.
2. Set the rotary switch to
Ω
3. Connect the test leads across with the object being measured. The measured
value shows on the display.
