(for blasting operations)

                                                        SPECIFICATIONS:

                                                        #          it is a hand held type digital ohmmeter.

                                                        #          it is a  4 digit ohmmeter ( 4.5 Digit is also available on specific order)

                                                        #          its range is from 1 to 1999 ohms.

                                                        #          the short circuit current is approx. 5 MilliAmps.( As per IS:5780)

                                                        #          the weight and dimensions are:

                                                        Weight  -         300 gms. approx. with battery

                                                                    Length  -         160 mm

                                                                    Breadth-            90 mm

                                                                    Height  -            40

                            OPERATIONS:

                                                    ·               Open back cover and insert one 9Volts alkaline battery.

                                       ·               Connect the blasting cable end of the series detonator circuit to the terminals at the top end.

                                       ·               Press switch on the side to display resistance in ohms.

                                       ·               If ‘1’ is displayed then either the series circuit is open or resistance is above the model range.

                                                   ·               It is recommended that the joints are made of clean and freshly exposed detonator legwires to get the least circuit resistance.

                                                   ·               Avoid shocks, moisture and water contact with the digital ohmmeters.

                                                   ·               Always put back the ohmmeter in the carrying case after use
