Measurement Operation(7)

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 continuity.

To test for continuity, connect the Meter as follows:

1. Insert the red test lead into the VΩ terminal and

the black test lead into the COM terminal.

2. Set the rotary switch to Ω and press SELECT

button to select measurement mode.

3. The buzzer sounds if the resistance of a circuit under

test is less than 50 Ω .

4. The buzzer may or may not sounds if the resistance

of a circuit under test is between 50 Ω to 120 Ω .

5. The buzzer does not sound if the resistance of a circuit

under test is higher than 120Ω.

Note

l The buzzer beeps once when pressing any buttons

at any rotary switch positions except at 2/20A positions

if the button is valid. If the button is not valid, it does

not beep. At 2/20A rotary switch position, the buzzer

is set not to beep.

l The buzzer beeps 5 times continuously on around

1 minute before entering the sleep mode. When it

is just before entering the sleep mode, it will have

one long beep to warn you.

l The LCD displays OL indicating the circuit being

tested is open.

l When continuity testing has been completed, disconnect

the connection between the testing leads and the

circuit under test and remove testing leads from the

input terminals.
