• This crowbar is activated by voltage. If the voltage is too high, that
crowbar will blow the fuse automatically to interrupt the circuit.
• The voltage between P1 and P2 is also protected for over voltage but
does not have a fuse.
• The tester has a temperature shut down. The temperature sensing is
done on the current regulation transistor.
• Should this over-temperature LED lit, allow the instrument to cool down
for a while before proceeding further.
• The milliohm meter, with its measuring range of 100u ohms to 2000
ohms, is suitable for a wide range of applications such as:
1. Measuring the winding resistance of electric motors, generators and
transformers.
2. Bond testing in mines, aircraft, railways, ships, domestic andindustrial
wiring installations.
3. Measuring the ring main continuity testing in industrial and domestic
wiring installations
4. Measuring resistance in electronic equipment such as shunts, pcb
tracks, switch and relay resistance.
5. Checking compression joints on overheads lines.
6. Testing and maintenance of switchboard /sub-station equipment on
such items as fuses, joints, contacts and bonds.
