Applications apart from general low-ohm measurements:
- measuring low value contact resistances at
welding seams and riveted joints
- determination of low-resistance transitions at outer skins of aircraft
(lightning protection, wick test),
and for general low-resistance measurements.
The METRAHit.27 is a compact, rugged and reliable instrument, which is equally suitable for precision
measuring and recording tasks in the factory, for on-site service and in the laboratory:
Adjustment of shunts in instrumentation.
Testing of electrical connections at conductor bars for openpit mining, in potential bonding systems,
and for industrial and household applications.
Testing of cable resistance, wiring, shunt resistors in PCBs and thick-film circuits.
Measurement of contact resistance in relays, contactors and power interrupters.
Testing of resistance in fuses, as well as conductor resistance in heavy current circuits.
Testing of winding resistance in transformers, coils, small motors etc.
Testing of discharge resistance on aircraft, and at aircraft outer skin components.
Contact resistance testing in uninterruptible power supplies.
Measurement of cell voltages, for example in on-board batteries and emergency power supplies.
Contact resistance testing at welding seams.
