If

 reading with shorted test leads is not

0.5

, check for

loose test leads, incorrect function selection, or enabled Data
Hold function.

l

For high-resistance measurement (

), it is normal to

take several seconds to obtain a stable reading.

l

The LCD displays        indicating open-circuit for the tested
resistor or the resistor value is higher than the maximum
range of the Meter.

l

When resistance measurement has been completed,
disconnect the connection between the testing leads and the
circuit under test, and remove the testing leads away from the
input terminals of the Meter.

D.Testing for Continuity

Measurement Operation (4)

(figure 6)

BLUE

 button to select

To avoid damages to the Meter or to the devices under test,
disconnect circuit power and discharge all the high-voltage
capacitors before testing for continuity.

To test for continuity, connect the Meter as below:
1. Insert the red test lead into the

HzV

terminal and the black

test lead into the

COM

 terminal.

2.

Model UT60C/UT60E:

 Set the rotary switch to

measurement mode.

Model UT60B:

Set the rotary switch to

and press

measurement mode.

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

less than around 70

Warning

and press

BLUE

 button to select

Note

l

The LCD displays

 indicating the circuit being tested is

open.
