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 gure 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 VΩHz 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.
