Temperature Calibration Adjustment (V5022)
Temperature Calibration Adjustment is a ± 3276.7 EC or EF value which is added to the controller
measured Process Temperature. This location can be used to remove inaccuracies due to thermocouple
cold junction compensation errors (see page 2.7) and temperature input device errors (typical
thermocouple device inaccuracy is ±1 to ±3 EC). If no adjustment is required then this location should
be set equal to zero.
Process Temp. (V5005) = Actual Temp. (measured) + Cal. Adjustment (V5022)
Actual Temperature = 24.6 EC
Examples:
Process Temperature = 25.2 EC
Temperature Calibration Adjustment = 32768+6 = 32774 = -.6 EC
Actual Temperature = 28.2 EC
Process Temperature = 26.3 EC
Temperature Calibration Adjustment = 19 = +1.9 EC
TEMPERATURE CONTROLLER MEMORY MAP, 4 LOOPS
The following example V-Memory map shows the addressing for all four loops of a Temperature
Controller Module with a Table Beginning Address of V5000. Any V-Memory address maybe specified
as the loop table starting address for a given module. Normally retentive V-Memory is used to store loop
parameters (V2000-V7377).
