CONTINUITY TESTS - Ω RANGES
1. Select the desired ohm range, 3Ω or 500Ω.
2. Short the test leads, press test button and adjust the ohms zero ADJ to
zero the pointer on the 0Ω (green scale).
3. Check the circuit is not LIVE.
4. Connect the test leads to the circuit under test. Press the test button.
Read the selected range directly.
GENERAL
● For AC voltmeter, do not press the test button, this is the default mode of
the instrument.
● AC voltmeter operates without batteries.
● Insulation or continuity mode: for continuous operation, press and turn the
test button.
SAFETY PRECAUTION
● The circuit must not be LIVE, conduct initial checks first. If at any time ,
the "LIVE" circuit light is illuminated, or the warning buzzer sounds - DO
NOT PROCEED, the circuit is live.
● Using the instrument in Insulation Mode may leave the
Circuits charged up if test leads are removed too quickly.
Avoid this by releasing the test button while the test leads are still
connected to the circuit for a few seconds.
9. Preparation for Measurement
Before testing Always check the following.
At Power "ON", check that Bat. OK led illuminate and check that there is no
visual damage to the Instrument or test leads.
Check the test Leads continuity:
1. Connect the leads to the Instrument.
2. Zero the test leads while on the 3 ohm range.
3. This will indicate that the continuity of the test leads is Ok.
4. Verify that the test leads insulation is in good condition.
