MGR10 A/B/C - Revision : I (for 7.0 software revision) 284.4 Temperature CompensationPress onto select the setup menu for temperature compensationThe temperature compensation mode should be used when measurements are required to be referencedto 20C. This is particularly useful when measuring materials with a high temperature coefficient suchas copper, as the ambient temperature varies so will the resistance value being measured. Using thetemperature compensation mode references all values back to a temperature of 20C.The true resistance value measured will be displayed in large digits in the center of the display and thecompensated resistance will be displayed in smaller text below.The compensation formula is :))20(1( CtRxRc With : Rt = resistance value @ t temperatureRc = resistance @ 20°C = 3980 ppm/°C or 4100 ppm/°C according to the materialt = measurement temperatureMode : Press on [Mode] to select the temperature compensation Press on [Ext] to select an external temperature sensor .This mode require the connection of aPT100 sensor on the front panel connector named Pt100..COMPCOMPCompensation : On MANUAL COPPERMode Ref On Off Quit
