3. The status display reads INPC. Connect the reference voltage used to define full scale out-
put current as described in PAR 3.7 .
4. When the reference voltage is at the desired value, click the PRESS TO ACCEPT button to
accept the value. When the calibration is saved, this voltage value will be equivalent to full
scale output current. NOTE: The full scale output current is determined by the virtual
settings in effect.
5. The status display will not change. Proceed to PAR. 4.4.4 to exit calibration.
4.4.4 CALIBRATION EXIT (VISA DEMO)
NOTE: Clicking the Calibrate CLOSE button on the main panel will exit calibration WITHOUT
saving any calibration data.
1. Click the SAVE CALIBRATION button on the calibration window to save this calibration.
2. The Calibration window automatically closes and the Virtual Model window automatically
opens.
3. The virtual model settings can be changed after the password has been properly entered.
NOTE: The virtual model is always reset following calibration. If voltage calibration is com-
pleted (regardless of whether or not current calibration is completed), the virtual model
voltage is set for maximum rated voltage, and current is set to the value corresponding
to 1200 Watts. If a current calibration is completed, but no Voltage calibration, the vir-
tual model current will be set for maximum rated current and voltage is set to the value
corresponding to 1200 Watts.
4.5 CHANGING THE CALIBRATION PASSWORD
The 4-digit password is required for to enter calibration mode. The factory default password is
listed in Table 4-1. To change the password from the front panel proceed as follows:
1. If the status display shows SET, tap either the CURRENT or VOLTAGE controls to take the
unit out of setpoint mode (status display goes from SET to blank)
2. Hold the PROTECT switch in and use a thin tool (e.g., a paper clip), to press the FUNCTION
switch. Status display reads PASS.
NOTE: To exit this procedure without changing the password, rotate the VOLTAGE control.
3. Tap the DC OUTPUT switch. Status display reads OLD?.
4. Rotate the CURRENT control until DC AMPERES display shows old password. Tap the DC
OUTPUT switch to enter. Status display shows NEW?.
5. Rotate the CURRENT control until DC AMPERES display shows new password. Tap the DC
OUTPUT switch to enter. Status display shows RPT?.
6. Rotate the CURRENT control until DC AMPERES display reads new password. Tap the DC
OUTPUT switch to enter. Status display reads DONE and the unit returns to setpoint mode.
