TEC Calibration
This chapter describes how to calibrate the TEC modules.
7.3.1
Recommended Equipment
Recommended test equipment for calibrating the module is listed in Table 11.
Equipment other than that shown in the table may be used if the specifications meet
or exceed those listed.

h.
Once the actual voltage value is entered via the LAS:LDV command,
the 6000 leaves the current calibration mode.
If, at any time prior to the second LAS:LDV, a command other than
LAS:LDV or LAS:CAL:LDV? is sent to the 6000, the 6000 will
cancel the calibration mode and then process the command(s).
The *OPC? query may be used to determine when the calibration is
completed.
The operation complete flag (bit 0 of the Standard Event Status
Register) may be used to trigger an interrupt. This type of interrupt is
enabled by setting bit 0 of the Service Request Enable register and
using the *OPC command.
