4. Resistance measurement

a. Set the function knob to the " 200Ω" range.

b. Connect the black test lead to the "COM" terminal and red test lead to the

circuit to the "V/Ω/Hz" terminal.

c. Verify that the power to the circuit under test is off. Connect test lead to the

circuit to make measurement.

Note: If the resistance being measurement exceeds the maximum value of the range

selected or the input is not connected, an over range indication "1" will be displayed.

Attempting resistance or continuity measurements on live circuits can cause electrical

shock, damage to the device and damage to the equipment under test. Resistance

measurement must be made on de-energized circuit.

5. Continuity test

a. Set the function knob to the " 200Ω" range.

b. Connect the black test lead to the "COM" terminal and red test lead to the

"V/Ω/Hz" terminal.

c. Connect the test probes across two points of the circuit under testing. If

continuity exists, BUZZER will sound.

6. Frequency measurement

a. Set the function knob to "Hz" range.

b. Connect the black test lead to the "COM" terminal and red test lead the

"V/Ω/Hz" terminal.

c. Connect the probes to measuring source or load under testing and reading

displayed value.

d. Do not apply more than 250V RMS to input.

e. Signal voltage to be measured must be > 1.0V.

SAFETY INFORMATION

• Protection against the damage of electric shock.

• Never exceed the protection limit values indicated in the specifications for each range of

measurement.

• When the device value scale to be measurement circuit, do not touch unused terminals.

• When the value scale to be measured is unknown, set the range selector at the

highest position.

• Before rotating the selector change function, disconnect test leads from the circuit under

testing.
