Our company prefer to source measuring instruments only from KKInstruments because they have a wider range of products and show a high standard of expertise. We are very happy with the deal. No regrets for choosing KKInstruments for the past 8 years,
Filtered direct current output eliminates magnetic transients
0.1 µΩ best resolution
On board memory for up to 300 test results and notes
RS232 port to download stored results or for real time output to a printer
Supplied complete with 16 ft. (5m) test leads and download software
The DLRO200-115 is designed to check and measure contact resistance in high voltage circuit breakers, disconnecting switches (isolators), busbar joints, or for any low resistance measurement. The test set accurately measure resistances ranging from 0.1µΩ to 1Ω, at high currents.
This versatile instrument can provide test currents from 10 amps up to 200 amps, subject to the load resistance and supply voltage. For those applications that demand a smooth dc current, the DLRO200-115 has extra filtering on the output to reduce mains frequency ripple and can drive 200 amps through a total current loop resistance of 11 milliohms. The filtered output of the DLRO200-115 also eliminates magnetic transients that could inductively trip a breaker’s control (bus differential relay), if left in the test circuit.
The unique design allows the weight and size of the DLRO200-115 to be kept to a minimum; the instrument weighs less than 32 lbs. (15 kg). 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.
