MGR10 A/B/C - Revision : I (for 7.0 software revision) 121.7 Common specification to all model numbers1.7.1 Temperature compensationThe accuracy of the temperature measurement is ±0.1% and uses a standard Pt100 sensor. Thisaccuracy does not include errors due to the sensor itself. The temperature measurement range is0…+40C and the resistance measurement is referenced to 20C when this option is used.Accuracy of the MGR10-04 sensor : +/- ( 0.2% + 1°C)1.7.2 Lead resistanceA maximum lead resistance of 0.5 / Imes ( = 0.05 for 10A and 500 for 1mA ) ispermissible in each of the four measuring leads.1.7.3 Mains supplyUniversal power inlet Mains : 115/230V~ 10% single phase 47 to 63 Hz. Power consumption : 40VA without load, 70 VA maximum. Switching from 115 to 230 volts by switch in the line input plug. Temporized fuse protective in rear panel- 2AT for 230V 4AT for 110V. Battery powered with built in charger ( MGR10A version) The two batteries used are 5Ah, and the following performance can be expected fromfully charged batteries:o Digital :11 hours continuous use, with backlight on, and IEEE and PLC cardsfitted.o Analogue: Over 6000 simple measurements in FAST mode, using 10Ameasuring current. (Or approximately 3000 measurements using SLOWmode).The battery condition is constantly monitored, and if it is low, a warning symbol is displayed .Inthis situation operate as follows : Connect a mains cable on the unit rear mains socket Connect the mains cable on the mains Switch the rear panel switch in the ON position The FAST red Led lamp should light on to indicate the battery charging mode When the red Led lights off , the charge is over
