CHAPTER 4
The TEC:ENABle:OUTOFF? query returns the value of the status outoff enable register of the TEC
operations (things which will turn the TEC output off).
Notes The enabled TEC outoff events and conditions (which can turn the TEC output off) can be set by
using the TEC:ENABle:OUTOFF command.
Examples "TEC:ENAB:OUTOFF?" −response: 258, means that a Sensor Type Change Condition or a Voltage
Limit Condition will cause the TEC output to be turned off.
"Radix Hex; TEC:Enab:Outoff?" −response: #H17FB, means that all of the above conditions will
cause the TEC output to be turned off.
"Radix Bin; TEC:Enab:Outoff?" −response: #B1001, means that the High Temperature Limit and TE
Current Limit conditions will cause the TEC output to be turned off.
The TEC:EVEnt? query returns the value of the status event register of the TEC operations.
Notes The TEC conditions which are reported to the status byte are set via the TEC:ENABle:EVEnt
command.
The TEC event status is only cleared when the event status is read or a *CLS command is issued,
while the condition status is constantly changing.
Examples "TEC:EVE?" −response: 513, means that the Output went In or Out of Tolerance and the TE
Current Limit events have occurred since the last TEC:EVEnt? query.
"Radix Hex; TEC:Event?" −response: #H82, means that the Voltage Limit and TE Module Open
events have occurred since the last TEC:EVEnt? query.
