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.
The TEC:GAIN command sets the TEC control loop gain.
Parameters An <nrf value> between 1 - 300, the value will be stored to the nearest of: 1, 3, 10, 30,
100, or 300.
Notes If the user enters a gain value which is greater than 300, a value of 300 will be stored. If
the user enters a gain value which is less than 1, a value of 1 will be stored.
If the user enters a value which is not legal, the LDC-3700C Series Laser Diode
Controller will round that value to the nearest legal value, if possible.
Examples "TEC:GAIN 100" -action: the TEC control loop gain is set to 100.
"Tec:gain 3" -action: the TEC control loop gain is set to 3.
"TEC:Gain 200" -action: the TEC control loop gain is set to 100 (the LDC-3700C Series
Laser Diode Controller rounds 200 to the nearest valid number).
