ValueTronics International, Inc. Milli Ohmmeter M227B

The M227B is a milli ohmmeter from Gossen Metrawatt. Features: Insulation tester, milliohm resistance meter and multimeter with memory1 Insulation resistance tester- Testing with 50 to 500 V for components, cables and conductors, for example in aircraft and in on-board electrical systems LCD panel with background illumination- High contrast, even under adverse ambient light conditions Compact and multifunctional- Can be used advantageously in aircraft cockpits as well as in other constricted spaces, which would otherwise require the use of several individual instruments Mains power or storage battery operation- Furnished with 3 NiMH storage batteries and a mains power battery charger as standard equipment for optimized instrument availability and low operating costs DAkkS calibration certificate as standard feature- Reduced operating costs for use within ISO 9000 quality systems, documented traceability Accessories: 1 - GH18 protective rubber cover with carrying strap 3 - size AA NiMH storage batteries 1 - NA HIT 27 mains power battery charger 1 - KS17-S measurement cable set 1 - set of Kelvin clips KC4 (1 set = 2 each) 1 - abbreviated operating instructions 1 - operating instructions D/GB/F 1 - DAkkS calibration certificate Applications: The METRA HIT 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 The Gossen Metrawatt METRA HIT 27I (M227B) is used additionally for service and repair work performed on airplane and helicopter electrical systems (voltage, insulation, milliohm and temperature measurement). In addition to its own multimeter functions for electrical quantities, the instrument also includes a mega-ohm measuring function with insulation test voltages of 50, 100, 250 and 500 V, as well as temperature measurement with Pt100 and Pt1000 sensors.
