Calibration
c.
Input the actual voltage, in mV, measured by the external voltmeter (as
an <nrf value>) via the TEC:R <nrf value> command.
If, at any time prior to TEC:R, a command other than TEC:R or
TEC:R? is sent to the 8000, the 8000 will cancel the calibration mode
and then process the command(s).
Once the TEC:R 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.
Measure and record the exact resistance of your 100 Ω metal film
a.
resistor. With the TEC output off, connect the metal film resistor to the
sensor input of the TEC Module.
b.
Go to the single module display by first pressing the MENU button,
then the Modules soft key, then the slot soft key that corresponds to the
module to be calibrated.
c.
Press the Setup soft key and select the RTD as the Sensor Type. Press
the Prev soft key to return to the single display.
d.
Go to the Calibration Screen. This is done by pressing the Menu
button, Config soft key, Calibrate soft key; then the soft key(s) that
correspond to the module to be calibrated.
d.
Enter the TEC sensor calibration mode by pressing the Sensor soft key.
Follow the on-screen instructions to complete the calibration. The
calibration can be canceled without affecting the stored constants if the
Cancel soft key is pressed at any point prior to completing the
calibration.
Measure and record the exact resistance of your 100 Ω metal film
a.
resistor. With the TEC output off, connect the metal film resistor to the
sensor input of the TEC Module.
b.
Enter the TEC:CHAN command to select the channel [,suchannel] to
be calibrated. Send TEC:SENS 5 to select the RTD sensor, followed
by the TEC:CAL:SEN to enter sensor calibration mode.
