Thanks to its very good accuracy and its rugged construction, this microhmmeter can bMfed in laboratories as well as in industry. Its main applications are measurements on : transformers, chokes, electrical motors, cables, switches, circuit breakers, relays, fuses surface, contact grounds Manual or automatic temperature compensation done according to copper or TECHNICAL CHARACTERISTICS • Manual / Automatic range • Battery (MGR10A) and mains supply (MGR10) versions • RS232C, PLC or IEEE488-2 interfaces LOW RESISTANCE MEASUREMENT Resistance • Resistance measurement : • Auto or manual range selection with current adjustable by range • Measurement current : From 1|uA to 10 A according to range and manually adjustable in % • Accuracy : ± 0.1 % (pulsed in battery mode, pulsed or DC with mains charger) • Current direction : Manual or continued with the selection of the current +VE, -VE, or +VE and -VE with the average calculated This latter option removes thermal EMF errors from the measurements • Voltage in open circuit : 20 mV and 50 mV with protection against the inductive charges and the over voltage (415 V) • Temperature measurement : From 0 to 100° C Displayed in deg C, F, K Compensation according to the resistance materials (copper, aluminium...) • Length of cable : Values can be displayed in Q, Q/Km or Km • Measurement threshold adjustable with low and high limits • Visual (red/green leds) and audible signals for results Data logging • 4000 measurement memories with measurement results date and time • 4 banana plugs 4 mm on the front panel • RS232 interface between PC and MGR10 connection • 240x64 LCD matrix display with backlight • LCD numerical screen with 30.000 digits resolution • Operating time : 11 hours or 6000 measurements at 10 A GENERAL CHARACTERISTICS • Bench style metal case Dimensions Rel. humidity up to 80 % none condensing Storage temperature • Pollution 2 : conducting pollution caused by condensation Overload category • Connected to the ground by power cord International standards Powering Business Worldwide
