Model UT804: OPERATING MANUAL

Figure 3-11. Continuity Test

F. Testing for Continuity

Warning

To avoid harms to you, please do not attempt to

input voltage higher than 60V DC or 30V AC.

To avoid possible 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, set up the Meter as Figure 3-11

and do the following:

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

black test lead into the COM terminal.

2. Set the rotary switch to

; press SELECT button

to select

measurement mode and connet the test

leads across with the object being tested.

3. The beeper comes on continuously for open

conditions, that is test resistance around < 50 .

4. The display shows the tested resistance load value.

The unit is .

The SELECT button cycles among resistance, continuity,

and diode.

Note

Open circuit voltage around –1.2V and range is

400 measurement range.

When continuity testing has been completed,

disconnect the connection between the testing leads

and the circuit under test and remove the test leads

away from the input terminals.
