LDT-5500B Series Device-Dependent Commands
The TEC:CAL? query is used to determine that the LDT-5500B Series Temperature
Controller is ready for a value to be entered during the calibration cycle.
None.
This query can be used to poll the LDT-5500B Series Temperature Controller after the
unit has entered into remote calibration mode. If the response is 1, the LDT-5500B is
ready to receive a calibration value.
"TEC:CAL?" - action: 1, means the LDT-5500B is ready for the user to enter in a
measured value.
The TEC:GAIN command sets the TEC control loop gain.
The TEC:GAIN? query returns the value of the control loop gain.
A value of 1, 3, 10, 30, 100, or 300.
If the user enters a gain value which does not equal 1, 3, 10, 30, 100, or 300, the
instrument will ignore the command.
"TEC:GAIN 10" - action: sets the TEC control loop gain to 10.
"TEC:GAIN?" - response: 300, means the TEC control loop gain is set to 300.
The TEC:ITE command sets the TEC control current set point. It is also used to enter the
TEC current calibration value.
The TEC:ITE? query returns the value of the measured TEC output current.
A value which represents the ITE set point current, in Amps. In ITE current calibration
mode, the value represents the measured current value in Amps.
The TEC:ITE set point command is only used in constant ITE mode.
The TEC:ITE? query can be used in all modes of operation.
"TEC:ITE 2.5" - action: sets the TEC current set point to 2.5 Amps if the LDT-5500B is in
ITE mode.
"TEC:ITE?" - response: 1.23, means the measured TEC output current is 1.230 Amps.
