Figure B-1. Verification & Calibration Test Setup
Performing the Verification Tests
NOTE:
The verification procedure can only be performed using the SCPI language commands.
Use either the front panel
Address
key to access the LANG command, or use the
SYSTem:LANGuage command to change the programming language to SCPI.
The following procedures assume you understand how to operate the dc source from the front panel as
explained in chapter 5.
When performing the verification tests from an GPIB controller, you may have to consider the relatively
slow settling times and slew rates of the dc source as compared to computer and system voltmeters.
Suitable WAIT statements can be inserted into the test program to give the dc source time to respond to
the test commands.
Perform the following tests for operation verification in the order indicated.
1. Turn-On Checkout
2. Voltage Programming and Measurement Accuracy
3. Current Programming and Measurement Accuracy
