CRM+ Series
The new super light Contact resistance meters with battery operations with ultra-capacitor technology which enable kit to reach 100A /200A DC mark quickly, reducing the test time. CRM directly measures micro-ohm values at 100 / 200 Amps DC under live EHV switchyard conditions quickly & accurately.
CRM 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. CRM measures millivolts signal in the presence of kilovolts noise. CRM is equally suitable for MV / HV / EHV equipment’s and is very useful to Power Utilities, Equipment Manufacturers, Testing & Commissioning Companies and Test Laboratories etc.
• It is the lightest available contact resistance meter.
• Measure Contact Resistance with 4 wire method
• 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.
• 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.
• Fool-proof connections and repeatability are ensured by SCOPE’s specially designed proprietary Ck clamps.
• Mains as well as rechargeable Li-ion battery operated. In built battery monitor and cut off circuit for protection against battery deep discharge.
• Kit can be operated in Stand-alone mode or PC control mode
• No ON/OFF duty cycle
• Enclosed in ultra-rugged IP67 class hard molded case.
• PC Downloading & Analysis including ‘Trend Analysis’ possible with “CData CRM” Software supplied with kit.
• Available in 100A & 200A models CRM 100B+ and CRM 200B+ respectively
