Calibration 2-9
2. Press ENTER to start short-circuit calibration. While the unit is calibrating, it will
display:
CALIBRATING
3. When the unit is done calibrating, it will display the following prompt:
OPEN CIRCUIT
4. Remove the calibration short, and press ENTER. During this phase, the CALIBRAT-
ING message will be displayed.
DC volts calibration
After the front panel short and open procedure, the unit will prompt you for the first DC volt-
age: +10V. Do the following:
1. Connect the calibrator to the Model 2015 as shown in Figure 2-2. Wait three minutes to
allow for thermal equilibrium before proceeding.

Connections for DC volts and ohms calibration
NOTE
Although 4-wire connections are shown, the sense leads are connected and discon-
nected 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 sensing is to be turned off,
and connect the sense leads when external sensing is to be turned on.
2. Set the calibrator to output DC volts, and turn external sense off.
