10 HP E1411A/E1411B Service Manual

Chapter 1
General Information
Introduction This manual contains information required to test, adjust, troubleshoot, and
repair the HP E1411A and HP E1411B C-Size VXI 5 1/2-Digit Multimeters
(HP E1411 multimeter). See the HP E1326A/E1411A User’s Manual or the
HP E1326B/E1411B User’s Manual for additional information on the HP
E1411 multimeter. Figure 1-1 shows the HP E1411A and E1411B
multimeters.
Safety
Considerations This product is a Safety Class I instrument that is provided with a protective
earth terminal when installed in the mainframe. The mainframe, multimeter,
and all related documentation should be reviewed for familiarization with
safety markings and instructions before operation or service.
Refer to the WARNINGS page (page 4) in this manual for a summary of
safety information. Safety information for testing, adjusting, and service
follows and is also found throughout this manual.
Figure 1-1. HP E1411A/B Multimeters
Chapter 1 General Information 11

Warnings and
Cautions This section contains WARNINGS which must be followed for your
protection and CAUTIONS which must be followed to avoid damage to the
equipment when performing instrument maintenance or repair.
WARNING SERVICE-TRAINED PERSONNEL ONLY. The information in this
manual is for service-trained personnel who are familiar with
electronic circuitry and are aware of the hazards involved. To
avoid personal injury or damage to the instrument, do not
perform procedures in this manual or do any servicing unless
you are qualified to do so.
CHECK MAINFRAME POWER SETTINGS. Before applying
power, verify that the mainframe setting matches the line
voltage and the correct fuse is installed. An uninterruptible
safety earth ground must be provided from the main power
source to the supplied power cord set.
GROUNDING REQUIREMENTS. Interruption of the protective
(grounding) conductor (inside or outside the mainframe) or
disconnecting the protective earth terminal will cause a
potential shock hazard that could result in personal injury.
(Grounding one conductor of a two-conductor outlet is not
sufficient protection.)
IMPAIRED PROTECTION. Whenever it is likely that instrument
protection has been impaired, the mainframe must be made
inoperative and be secured against any unintended operation.
REMOVE POWER IF POSSIBLE. Some procedures in this
manual may be performed with power supplied to the
mainframe while protective covers are removed. Energy
available at many points may, if contacted, result in personal
injury. (If maintenance can be performed without power applied,
the power should be removed.)
USING AUTOTRANSFORMERS. If the mainframe is to be
energized via an autotransformer (for voltage reduction) make
sure the common terminal is connected to neutral (that is, the
grounded side of the main’s supply).
CAPACITOR VOLTAGES. Capacitors inside the mainframe may
remain charged even when the mainframe has been
disconnected from its source of supply.
12 General Information Chapter 1

WARNING USE PROPER FUSES. For continued protection against fire
hazard, replace the line fuse(s) only with fuses of the same
current rating and type (such as normal blow, time delay, etc.).
Do not use repaired fuses or short-circuited fuseholders.
CAUTION Static electricity is a major cause of component failure. To prevent
damage to the electrical components in the multimeter, observe
anti-static techniques whenever working on the multimeter.
Multimeter
Description The HP E1411 multimeter is an "instrument" in the slots of a VXIbus
mainframe. As such, it is assigned an error queue, input and output buffers,
status registers, and is allocated a portion of mainframe memory for reading
storage.
NOTE Instruments are based on the logical addresses of the plug-in modules. See
the HP 75000 Series C Installation and Getting Started Guide to set the
addresses to create an instrument.
The instrument may consist of a multimeter only (stand-alone operation), or
can include relay or FET multiplexers (scanning multimeter operation). The
instrument is operated from a computer using Standard Commands for
Programmable Instruments (SCPI) language.
In stand-alone operation, input signals are connected to the multimeter’s
external (faceplate) terminals. In scanning multimeter operation, input
signals are connected to the multiplexer channels. The multimeter is linked
to relay multiplexers via an analog bus cable. The multimeter is linked to
FET multiplexers via an analog bus cable and a digital bus cable.
Multimeter
Specifications Multimeter specifications are listed in Appendix A of the HP
E1326A/E1411A User’s Manual or the E1326B/E1411B User’s Manual.
These specifications are the performance standards or limits against which
the instrument may be tested.
Chapter 1 General Information 13

Multimeter Serial
Numbers Multimeters covered by this manual are identified by a serial number prefix
listed on the title page. Hewlett-Packard uses a two part serial number in the
form 0000A00000, where 0000 is the serial prefix, A is the country of
origin (A=USA) and 00000 is the serial suffix. The serial number prefix
identifies a series of identical instruments. The serial number suffix is
assigned sequentially to each instrument.
If the serial number prefix of your instrument is greater than the one listed
on the title page, a Manual Update (as required) will explain how to adapt

Installation
Introduction This chapter provides information to install the HP E1411 multimeter,
including initial inspection, preparation for use, environment, storage and
shipment.
Initial
Inspection Inspect the shipping container for damage. If the shipping container or
cushioning material is damaged, keep the container until the shipment
contents have been checked and the instrument has been checked
mechanically and electrically. See Figure 1-1 in Chapter 1 - General
Information for shipment contents. See Chapter 4 - Verification Tests for
procedures to check electrical performance.
WARNING To avoid possible hazardous electrical shock, do not perform
electrical tests if there are signs of shipping damage to any
portion of the outer enclosure (covers, panels, etc.).
If the contents are incomplete, if there is mechanical damage or defect, or if
the instrument does not pass the electrical performance tests, notify your
nearest Hewlett-Packard Sales and Support Office. If the shipping container
is damaged or the cushioning material shows signs of stress, notify the
carrier as well as Hewlett-Packard, and keep the shipping materials for the
carrier’s inspection.
Preparation for
Use See Chapter 2 of the HP E1326A/E1411A User’s Manual or the
E1326B/E1411B User’s Manual to prepare an HP E1411 multimeter for
use. See the appropriate mainframe user’s manual(s) to prepare your
mainframe. If your mainframe is not manufactured by Hewlett-Packard,
consult the manufacturer for a list of available manual(s).
Recommended operating environment for the HP E1411 multimeters is 0oC
to +55oC with relative humidity <65% (0 oC to +40oC). The instrument
should be stored in a clean, dry environment. For storage and shipment, the
temperature range is -40oC to +75oC with relative humidity <65% (0oC to
+40oC).
Chapter 2 Installation 15

Shipping the
Multimeter If you need to return an HP E1411 multimeter to Hewlett-Packard,
first remove any adapters or connectors before packaging the instrument for
shipment. When you return the instrument to Hewlett-Packard, attach a tag
to the instrument identifying the owner and indicating service or repair
required. In any correspondence, refer to the instrument by model number
and full serial number.
When shipping the instrument, we recommend using containers and
materials identical to those used in factory packaging, which are available
through Hewlett-Packard Sales and Support Offices. Mark the shipping
container "FRAGILE" to assure careful handling.
If you use other (commercially available) shipping materials, wrap the
instrument in heavy paper or plastic. Use a strong shipping container. A
double-wall carton of 2.4 MPa (350 psi) test material is adequate.
Use enough shock-absorbing material (75 to 100 mm layer; 3 to 4 inches)
around all sides of the instrument to provide firm cushion and prevent
movement in the container. Protect the front panel with cardboard. Seal the
shipping container securely and mark the container "FRAGILE" to assure
careful handling.

including:
•Multimeter operation
•Operator’s check (self-test)
Multimeter
Operation See the HP E1326A/E1411A User’s Manual or the E1326B/E1411B User’s
Manual for multimeter operation, including:
•Getting started
•Configuring the multimeter
•Using the multimeter
•Understanding the multimeter
•Multimeter command reference
•Multimeter specifications
•Multimeter error messages
•Register-based programming
Operator’s
Check The Operator’s Check for the HP E1411 multimeter consists of sending the
self-test (*TST?) command and checking the return. The operator’s check
can be used to verify the multimeter is connected properly and is responding
to the self-test command.
As required, see the mainframe user’s manual for information on address
selection. See the HP E1326A/E1411A User’s Manual or the
E1326B/E1411B User’s Manual for information on multimeter SCPI
commands.
Self-Test Procedure 1. Verify the multimeter is properly installed in the mainframe and
the mainframe has passed its power-on sequence test.
2. Execute the multimeter functional test using the *TST? command
(see example following).
3. A "0" returned means no self-test failure, while "1", "2", "3", or "4"
returned means a failure was detected. See Chapter 8 - Service for
troubleshooting information (see NOTE following).
Chapter 3 Operating Instructions 17

NOTE Test failures can be caused by improper cabling, improper selection of the
interface select code, primary, and/or secondary address setting. Verify
proper connection and address selection before troubleshooting.

Verification Tests
Introduction The three levels of test procedures described in this chapter are used
to verify that the HP E1411 multimeter:
•is functional (Functional Verification)
•meets selected testable specifications (Operation Verification)
•meets all testable specifications (Performance Verification)
WARNING Do not perform any of the following verification tests unless
you are a qualified, service-trained person and have read the
WARNINGS and CAUTIONS in
Chapter 1 - General Information .
Test Conditions /
Procedures For valid tests, all test equipment and the multimeter must have a one hour
warmup, the line voltage must be 115/230 Vac ±10%, and multimeter Auto
Zero must be set to ON. See Table 1-1, Recommended Test Equipment, for
test equipment requirements.
For best test accuracy, the ambient temperature of the test area should be
between 18oC and 28oC and stable to within ±1oC. You should perform the
Performance Verification tests at least once a year. For heavy use or severe
operating environments, perform the tests more often.
The verification tests assume the person performing the tests understands
how to operate the mainframe, multimeter and specified test equipment. The
test procedures do not specify equipment settings for test equipment, except
in general terms. It is assumed a qualified, service-trained person will select
and connect the cables, adapters, and probes required for the test.
Performance Test
Record Table 4-1, Performance Test Record for the HP E1411 Multimeter, at the
end of this chapter, provides space to enter the results of each Performance
Verification test and to compare the results with the
upper and lower limits for the test. You can make a copy of this form,
if desired.
Chapter 4 Verification Tests 19

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 HP 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 HP
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 HP 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 HP 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.
