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 0.1�Ω 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.
