Read these registers using the ENABle:OUTOFF? query.
The factory default values for these registers are 512 and 6159 for registers 1 and 0
respectively. The conditions that will cause the output to shut off are Upper or Lower
Temperature Limit, Sensor Open or Shorted, Upper or Lower Sensor Limit, and Internal
PCB Temperature Out of Tolerance.
If you set bit 4 in register 1, the output will shut off whenever the controlled temperature is
out of tolerance (specified using the LIM:TOL command). If the temperature is not within
the limits, you will not be able to turn on the output. You should wait until the temperature
is within your tolerance specification before setting this bit. To clear these registers send
ENAB:OUTOFF 0,0. To reset these registers to their default values send
ENAB:OUTOFF:DEF.
ENAB:OUTOFF 0, 7 action: sets the TEC Output-Off enable registers so that only a
Sensor Open (4) or an Upper or Lower Temperature Limit (1 and 2) condition will cause
the output to be automatically turned off.
