Digital microhmmeter CRM 200B+

portablelow-resistance

SCOPE introduces its next generation of hugely popular CRM series contact resistance meter, CRM200B+ in all new super light avatar, based on cutting edge ultra capacitor technology. CRM incorporates some state of the art hardware & smart software features making it a must have tool for testing & maintenance engineers. CRM directly measures micro-ohm values at 200A DC under live EHV switchyard conditions quickly & accurately. It is specially designed to reliably measure micro-ohm contact resistances of Circuit Breakers, Isolators, Busbar joints, earth switch joints, welded joints etc., under the hostile electrostatic noise found in live EHV switchyards up-to 765 kV. SCOPE’s ability to make electronics work in such environment enables CRM to measure mili-volts signal in the presence of kilo-volts noise. CRM is equally suitable for MV / HV / EHV equipments and is very useful to Power Companies, Equipment Manufacturers, Testing & Commissioning Companies and Test Laboratories etc. FEATURES • A radically new design makes CRM the lightest available contact resistance meter. • Simultaneous & multiple samples of test current and voltage drop are taken at high speed using fast & high resolution ADCs. • Resistance will be calculated by taking actual V/I ratio and averaging of individual samples giving stable & accurate results. It makes it independent of test current variations. • Autoranging. Direct display of micro-ohm value does away with manual calculations. • In built real time clock, memory and printer. Test time stamping on each record enables time references for future use.
