The 8000 will be ready to receive the first measured current value
when, after a TEC:CAL:ITE? query is sent, a "1" is returned.
c.
Input the actual current (as an <nrf value>) via the TEC:ITE <nrf
value> command. The 8000 will then drive the current to 25% of the
initial set point.
The 8000 will be ready to receive the second measured current value
when, after a TEC:CAL:ITE? query is sent, a "1" is returned.
d.
Input the second actual current (as an <nrf value>) via the TEC:ITE
<nrf value> command. The 8000 will then drive the current to the
negative current value of the initial set point.
The 8000 will be ready to receive the third measured current value
when, after a TEC:CAL:ITE? query is sent, a "1" is returned.
e.
Input the third actual current (as an <nrf value>) via the TEC:ITE <nrf
value> command. The 8000 will then drive the current to 25% of the
negative current value of the initial set point.
The 8000 will be ready to receive the fourth measured current value
when, after a TEC:CAL:ITE? query is sent, a "1" is returned.
f.
Input the fourth actual current (as an <nrf value>) via the TEC:ITE
<nrf value> command.
If, at any time prior to the last TEC:ITE, a command other than
TEC:ITE or TEC:ITE? is sent to the 8000, the 8000 will cancel the
calibration mode and then process the command(s).
Once the TEC:ITE value is sent, 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.
