Calibration for Current, Voltage & Switch Test Module (MA20)
The MA20 can be calibrated through the use of the span factor (userspan) and the Offset for the current and voltage modes. Record dis-
played current or voltage for two or more points. Determine if the nVision would benefit from an overal increase or decrease of the indicated reading and
modify using the userspan and offset feature of CrystalControl.
To setup the Switch Test feature, select the Setup Wizard button in the MA20 Module Config screen and follow the instructions.
Calibration for Temperature Modules (RTD100)
The RTD sensor can be calibrated through the use of the span factor (userspan) and the Base Resistance (Ro) at 0ºC. Record displayed
temperature for two or more temperature points. Determine if the nVision would benefit from an overall increase or decrease of the indicated temperatures
and modify using the userspan feature in CrystalControl. It is also possible to modify the RTD sensor resistance reading at 0 to a custom value other than the
default value of 100 Ω using the Base Resistance (Ro) at 0ºC in CrystalControl. Note, however, that the Ro offset will affect all RTDs used with the nVision and
should be used with care.
