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 HP-IB 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
