Com ma nd Reference
Queries the status of all pending overlapped command operations.
The response is a single value. A "1" indicates all overlapped commands are complete. A
"0" indicates overlapped commands are not complete.
This instrument has no overlapped commands.
*OPC? response: 1 means that commands are complete.
The OUTPUT command turns the controller output to the TEC on or off.
An <nrf value>; 1 = on, 0 = off.
After the TEC output is turned on, it may be useful to wait until the output is stable before
performing further operations, but it is not necessary.
The character strings "OFF" and "ON" may be used in place of "0" and "1".
OUTPUT 1 action: turns the output on.
OUTPUT OFF action: turns the output off.
The OUTPUT? query returns the controller output state.
The response is a value that represents the output state.
Although the output is on, the output may not have reached the set point value.
The output should always be off when connecting or disconnecting cables to the output
connector.
OUTPUT? response: 0, means that the TEC is off.
OUTPUT? response: 1, means that the TEC is turned on.
The PID command is used to set the PID constant for the instrument.
Three <nrf values> are required. The first represents P (the proportional term), the
second represents I (the integral term), and the third represents D (the derivative term).
Valid values for P are between 0 and 9999.99.
Valid values for I are between 0 and 999.999.
Valid values for D are between 0 and 999.999.
PID constants are only applicable in temperature and sensor modes. See Chapter 2 for
more details on setting PID constants.
PID 24,5.6,8.0 action: sets P=24.00, I=5.600, and D=8.000
