The TEC:ENABle:OUTOFF command sets the status outoff enable register of the TEC
operations (things which will turn the TEC output off).
Parameters An <nrf value> whose sum represents the enabled bits:
Notes The enabled TEC outoff bits can be read by using the TEC:ENABle:OUTOFF? query.
The value of the TEC outoff enable register is stored in non-volatile memory and is
retained at power-up.
The factory default setting for this register is #H5E8, or 1512 decimal.
The High Temperature Limit Condition, Sensor Open (While Output On) Condition, and
Sensor Type Change (While Output On) Event bits will not be in effect and will not cause
the TEC output to be shut off, if the LDC-3700C Series Laser Diode Controller is in ITE
mode.
WARNING: If the Output Out of Tolerance Change Event bit is set when the power is off,
the TEC output will not be able to be turned on until this bit is reset.
Examples "TEC:ENAB:OUTOFF 9" -action: enables the TEC status outoff register so that a High
Temperature Limit Condition or a TE Current Limit Condition will cause the TEC output to
be turned off.
"Tec:Enab:Outoff #H17FB" -action: enables the TEC status outoff register so that any
and all of the above conditions will cause the TEC output to be turned off.
