7. Simplified Instructions

       WARNING

This instrument must only be used by a competent trained 

individual. Consult the full operating instructions. Never press 

the test button before connecting test leads to circuit to test.

 

 

      INITIAL CHECKS

1. Switch to "Batt. Check" and depress the test button. If the 

pointer does not move to "BAT. OK", the battery needs to be r

eplaced before proceeding.

2. 

Connect test leads to instrument, switch to 3Ω. 

Press and turn the test button (continuous mode), short the test

Leads. The pointer should swing from infinite towards zero. 

If not, the test leads or fuse (0.5A fast acting ceramic)

 maybe faulty.

 

       

INSULATION TESTS MΩ RANGES

1. Select the desired insulation test voltage range, 

250V, 500V, or 1000V.

2. Connect the leads to the instrument and circuit under test.

3. Check the circuit is not LIVE.

4. Press the test button. Read the red MΩ scale directly for 

500V, multiply by 0.5 (or divide by 2) for 250V 

and multiply by 2 for 1000V.

 

      

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.
