Intrinsically safe digital ohm meter is most suitable for testing blasting circuit for resistance and continuity before connecting to exploder. This intrinsically safe digital ohm meter can also 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 upto 9999 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.
