MICRO-OHMMETERS (AOIP INSTRUMENTATION)

MODEL OM21 is probably the most comprehensive Micro-ohmmeter available, and includes all of the features required to solve even the most difficult application measurement problems. These features include 4 wire measurement, three selectable test current levels for every resistance range, automatic temperature compensation for any metal co-efficient, automatic determination of heat rise in motors and transformers , alarm limits and outputs, DC, pulsed or alternating test current, to minimise heating effects and thermal emf errors in the test piece.1000 reading storage and RS232 interface are standard, GPIB interface and internal rechargeable battery are

MODEL OM16 is intended for field operation as a tester of ground bonds at current up to 10A. Dual built in sealed lead-gel batteries ensure long operational use between charges. Applications include aircraft earth bonding, testing of flexible welding cables in robotic applications. The maximum resolution is 0.1 uohm. OM16 is intended for indoor or outdoor use and has a wide choice of probes and test cables, generally 5m long for structural bond testing, and with extension cables available. The AMT013 triggered test probe on one lead and a Kelvin clip (AMT006 or 012) on the other enable one man operation with triggered and frozen reading – even on large structures.

Automatic Temperature Compensation is standard, and the AMT014 Pt100 temperature sensor can be plugged in to the top panel for ambient sensing, or used with an AMT015 extension cable to enable actual test piece temperature to be compensated.

RN5306 is a specialised hand held Safety Ohmmeter for checking explosive fuses, detonators and squibs etc. where the test current is normally always below 0.5mA, and cannot exceed 5mA with an internal fault, or 10mA even if two faults are present in any combination simultaneously on the instrument. Test voltage is restricted to 1v open circuit. Range is from 10mohm (resolution) to 2Mohm with either 4 wire (to 2kohm), or 2 wire with adjustable lead compensation, measurement available.
