Figure B-1. Verification and Calibration Test Setup
Performing the Verification Tests
The following procedures assume you understand how to operate the dc source from the front panel as
explained in chapter 5. Also, 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
Turn-On Checkout
NOTE: The dc source must pass turn-on selftest before you can proceed with the verification
tests.
Perform the Turn-On Checkout as directed in chapter 4.
