The TEC:LIM:ITE command sets the TE current limit value.
The TEC:LIM:ITE? query returns the value of the TE current limit.
Parameters A value representing the limit value of the TE current, in Amps.
Notes The ITE limit value is in effect for all modes of TEC operation. The ITE limit will limit the
TEC current in both positive and negative current directions.
Examples "TEC:LIM:ITE 3.5” - action: the TEC current limit is set to 3.500 Amps.
“TEC:LIM:ITE?” - response: 4.0, means the TEC current limit is 4.000 Amps.
The TEC:LIM:THI command sets the temperature limit value.
The TEC:LIM:THI? query returns the value of the temperature limit.
- where the response is the temperature limit set point value.
Parameters A value which represents the upper bound of the load temperature, in
o
C.
Notes The temperature limit value must be in the range -99.9
o
C to 199.9
o
C. This value also
becomes the maximum temperature set point. This value will force the TEC output to be
shut off if the temperature limit is reached.
Examples "TEC:LIM:THI 100.0” - action: sets the temperature limit to 100.0
o
C.
“TEC:LIM:THI?” - response: 35.0, means the temperature limit is set to 35
o
C.
The TEC:MODE:ITE command selects constant TE current control mode.
Parameters None.
Notes This mode keeps the output current constant, regardless of load temperature variations.
Changing modes causes the output to be forced off, and the new mode’s set point value
will be displayed.
Examples "TEC:MODE:ITE” - action: sets the TEC controller for constant TEC current operation.
