Service manual

The value in the "Measurement Uncertainty" column of Table 4-1 is
derived from the specifications for the source used for the test, and
represents the expected accuracy of the source. The value in the "Test
Accuracy Ratio (TAR)" column of Table 4-1 is the ratio of multimeter
accuracy to measurement uncertainty.
Verification Test
Examples
Each Performance Verification Test includes an example program to
perform the test. Each example uses address 70903 for the multimeter, and
an HP 9000 Series 200/300 computer running BASIC and Standard
Commands for Programmable Instruments (SCPI) commands. You may
need to change the multimeter address and/or command syntax to perform
the examples for your setup.
As required, see the mainframe or command module user’s manual for
information on address selection and cabling guidelines. See the
E1326A/E1411A User’s Manual or the E1326B/E1411B User’s Manual for
information on multimeter SCPI commands.
Functional
Verification
Test
The functional verification test for the E1411 multimeter consists of the
multimeter self-test. You can perform this test to verify the multimeter is
functional and is communicating with the mainframe, external computer
and/or external terminal.
Self-Test Procedure This test verifies the multimeter is communicating with the mainframe,
external controller, and/or external terminal by performing a multimeter
self-test. Do the following steps to perform the self-test:
1. Verify the multimeter is correctly installed in the mainframe.
2. Connect a power cable to the mainframe and set mainframe
power ON. Verify proper mainframe power-up sequence. (See
the mainframe user’s manual for additional information.) If
correct, proceed with step 3. If incorrect, troubleshoot the problem
before proceeding.
3. Execute the multimeter functional verification test using the
*TST? command. See the following example which uses an HP
9000 Series 300 computer with BASIC and a multimeter
address of 70903.
4. A "0" returned means no failure, while "1", "2", "3", or "4" returned
means a failure was detected. See Chapter 8 - Service for trouble-
shooting information.
