Calibration Setup
1. Disconnect the supply's AC power.
2. Disconnect the load from the power supply you want to calibrate.
3. Remove the cover to access the GPIB Interface PCB calibration potentiometers.
4. Ensure the power supply is connected for local sensing (factory default).
5. Connect a digital voltmeter (DVM) for voltage or OVP calibration, or, a current
shunt rated for the full output current of the supply and a DVM for current
calibration. See
Figure 4.1, Voltage Calibration Setup or Figure 4.2, Current
Calibration Setup .
6. Ensure the correct IEEE primary address has been set (rear panel switches
SW1-8 to SW 1-4). See “IEEE-488 Primary Address Selection” on page 24 for
information on address selection.
7. Set the power supply to REMOTE mode (rear panel switch SW1-1 ON).
8. Connect the IEEE controller to the power supply at connector J8.
9. Reconnect the AC power. Turn unit ON and allow the unit to warm up for 30
minutes.
