E
- End Calibration Mode
TYPE Calibration
EXECUTION Immediate
SYNTAX E Terminate Calibration Mode
DESCRIPTION
Note: This command is only for advanced users who perform their own calibration. It is not necessary
for normal, everyday operation.
To use this command the unit must be in Calibration Mode. The End Calibration Mode ( E ) command is then used
to take the unit out of Calibration Mode. Once this command has been executed the unit will no longer be in
Calibration Mode and the Enter Calibration Mode (
K ) command must be issued to re-enter Calibration Mode.
For more information on manual calibration, see chapter System Calibration.
EXAMPLE
PRINT#1, “OUTPUT07;K12345X” ‘ Enter Calibration Mode
‘ Apply precision voltage
PRINT#1, “OUTPUT07;H545X” ‘ Will calculate offsets for slave card 17 (TempScan/1100)
‘ Wait for command to complete
‘ Apply precision voltage of -50.0 mV
PRINT#1, “OUTPUT07;G545,1X” ‘ Calibrate negative gain for thermocouple, for slave card 17
(TempScan/1100)
‘ Wait for command to complete
‘ Apply precision voltage of +50.0 mV
PRINT#1, “OUTPUT07;G545,1X” ‘ Calibrate positive gain for thermocouple, for slave card 17
(TempScan/1100)
‘ Wait for command to complete
‘ Apply temperature of 90.0 °C
PRINT#1, “OUTPUT07;J21,2,90.0X” ‘ Calibrate cold junction offset for Channel 21 on the master
unit card
‘ Wait for command to complete
‘ Remove precision voltage
PRINT#1, “OUTPUT07;EX” ‘ End Calibration Mode
