Conforming to IS 5780-1970 the equipment is suitable for checking resistance of circuit. AMA Ohmmeter is available in 0-300, 0-600 Ohm and 0-1000 Ohm range.
General: Intrinsically safe Ohmmeter conforming to IS-5780-1970 is developed primarily for testing the circuit, either for electrical resistance or for continuity before connecting to the firing apparatus.
Approval: Ohmmeter is approved by DGMS, A govt of India Organisation vide his Intrinsically Safe Certificate No. 28 group I.
Construction: The meter is housed in elegantly polished teak wood/fibre glass body casing and provided with a leather carrying handle. Two terminals for shot firing cable leads, potentiometer for infinity adjustment and push button switch are conveniently located. A completely balanced and damped moving coil provides 'dead beat' deflection and steady reading unaffected by the angle at which the instrument is held. The scale is marked 0-300 ohms with open reading between 0.50 Ohms. The tolerance of the Ohmmeter is well within 3 %. An independently accessible battery hold houses a 1.5V dry cell which is the input source.
Infinity adjustment:
Before carrying out test for resistance the pointer should be set to INF (infinity) by pressing the push button switch and adjusting potentiometer screw. AMA DIGITAL OHM METER
The Digital Ohmmeter is most suitable for testing blasting circuit for resistance and continuity before connecting to exploder. The same can be used for all other forms of resistance testing. The unit is housed in moulded plastic box. Two heavy duty terminal and push button switch are conveniently located. Resistance up to 999 ohm can be measured.
OPERATION:
1. Connect Wire to the Terminal, 2. Press switch, Resistance will be displayed on the display board. 3. In case display does not show recheck the circuit and eliminate the defective detonator. 4. Use one 9 V cell.
