plays and prompts which lead you through the calibration of the KLP. This VISA compliant driver
works with many GPIB cards from suppliers such as National Instruments and Hewlett-Packard.
The following calibration procedure uses the “soft” front panel which is part of the VXI plug&play
driver for the KLP which can be downloaded from the Kepco website at: www.kepcopower.com/
drivers/.
Unzip the files and doubleclick on setup.exe to install the driver. The Kepco\klp folder will be
added to the Start - Programs folder. Doubleclick KLPCTRL.exe to run the program, and refer to
the KLP Developer’s Guide in the Kepco\klp folder for details about using the soft front panel.
For voltage calibration all loads must be disconnected and the sense terminals connected to the
corresponding output terminals. The digital voltmeter will be connected to the output of the
power supply. For current calibration after disconnecting all loads an appropriate shunt resistor
will be connected across the output terminals and the digital voltmeter will be connected across
the sense terminals of the shunt resistor.
1. Turn off power supply and disconnect load from output bus bar at the rear of the unit.
2. Verify that power supply is configured for local error sensing (See PAR. 2.7.5.1) .
3. For voltage calibration connect DVM to (M+, S+) and (M–, S–) of terminal block at the rear of
power supply.
4. For current calibration connect an appropriate shunt resistor (see PAR 4.2) across the output
terminals and connect DVM to shunt resistor terminals.
5. Turn on power supply, and after the status display shows
SET
, start the KLP VXI plug&play
demo program.
6. Click the Calibrate Access button on the VXI plug&play demo main panel: the button label
changes to Calibrate Close and the Calibration Window (Figure 4-1) opens with all buttons
disabled (grayed out) and PASSWORD appears in the text box near the top of the window.
