Connect the calibrator to the Model 2790 as shown in
minutes for thermal equilibrium.
Although 4-wire connections are shown, the sense leads are connected and dis-
connected at various points in this procedure by turning calibrator external
sense on or off as appropriate. If your calibrator does not have provisions for
turning external sense on and off, disconnect the sense leads when external sens-
ing is to be turned off and connect the sense leads when external sensing is to be
turned on.
Perform the calibration steps summarized in
•
Set the calibrator to the indicated voltage and make sure the unit is in operate.
(Use the recommended voltage if possible.)
•
Send the indicated programming command. (Change the voltage parameter if
you are using a different calibration voltage.)
•
Wait until the Model 2790 completes each step before continuing.
Ensure the calibrator has settled to the final value. You can do so by verifying
that the "Settled" indicator is off or by using the *OPC? (operation complete)
query.
