DLRO200-115

The DLRO200-115 is a low resistance Digital Ohmmeter measures contact resistance in high voltage circuit breakers, disconnecting switches (isolators), bus bar joints or for any other low resistance measurement. This test set accurately measures resistances ranging from 0.1µΩ to 1Ω, at high currents. A versatile instrument, it can provide test currents from 10 up to 200A, subject to the load resistance and supply voltage. For those applications that demand a smooth DC current, It has extra filtering on the output to reduce mains frequency ripple and can drive 200A through a total current loop resistance of 11mΩ. The filtered output of the ohmmeter also eliminates magnetic transients that could inductively trip a breaker’s control, if left in the test circuit. The unique design allows the weight and size of it to be kept to a minimum. This small size plus a water/dust ingress rating of IP54 makes the test set equally at home in the workshop, on the production floor or in the field.
