UT207A/208A/209A Operating Manual
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.
