Chapter 1
Getting Started with the HP E1326B/E1411B
Multimeter
About This Chapter
This chapter introduces you the B-size HP E1326B and C-size HP E1411B
51⁄2- Digit Multimeters. The main sections of the chapter are:
•Multimeter Overview. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Page 13
•Introduction to Operation. . . . . . . . . . . . . . . . . . . . . . . . . . . . Page 16
Note This manual is to be used with the HP E1326B or HP E1411B installed in
the HP 75000 Series B or Series C mainframe, and when the multimeter is
programmed using Standard Commands for Programmable Instruments
(SCPI) language or when it is programmed at the register level.
Multimeter Overview
The HP E1326B/E1411B multimeter is a register-based VXI instrument.
There are two different methods of programming the multimeter based on
the system configuration that it is used in.
If the HP E1326B is used in an HP E1300/E1301/E1302 B-size VXI
mainframe, or if the HP E1326B/E1411B is used in a C-size VXI
mainframe with an HP E1405/E1406 Command Module or with a computer
which has HP Compiled SCPI software, then it may be programmed using
SCPI language. This is the method described in Chapters 1 through 5.
If the HP E1326B is in a VME mainframe or the E1326B/E1411B is in a
C-size VXI mainframe and no HP Command Module or computer with
Compiled SCPI is present, then the multimeter must be programmed at the
register level. Appendix C covers register level programming.
The HP SCPI driver provides an error queue, input and output buffers,
status registers, and is allocated a portion of mainframe memory for reading
storage. This "instrument" may consist of the multimeter, or it can also
include multiplexers such as the HP E1345A/46A/47A/51A/53A and the
HP E1460A/76A. The instrument is operated from the mainframe front
panel or from a computer using the SCPI language.
Instruments are based on the logical addresses of the plug-in modules. The
HP VXIbus Systems Installation and Getting Started Guide explains how to
Chapter 1 Getting Started with the HP E1326B/E1411B Multimeter 13
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

set the addresses in order to create an instrument. The guide should be your
starting point toward using the multimeter. The functions and features of
the multimeter are presented in the following functional, electrical, and
physical descriptions.
Functional
Description The 51⁄2- digit multimeter can be used stand-alone, or combined with
multiplexers (for example, HP E1345A/46A/47A/51A/52A/55A/56A/
57A/58A or HP E1460A/76A) to form a scanning multimeter.
In stand-alone operation, input signals are connected to the multimeter’s
external (faceplate) terminals. In scanning operation, input signals are
connected to the multiplexer channels. The multimeter is linked to relay
multiplexer(s) via an analog bus cable. The multimeter is linked to FET
multiplexers via an analog cable and a digital bus cable.
Measurement
Functions The multimeter’s measurement functions are shown below. These functions
are typical of those required for many data acquisition and computer aided
test applications.
–DC Voltage
–RMS AC voltage
–2-Wire Resistance (scanning multimeter only)
–4-Wire Resistance
–Temperature (thermistors, RTDs, thermocouples)
Configuring the
Multimeter With MEASure or CONFigure, the multimeter is configured for
measurements using a single command. When necessary, low-level
commands are available to set configurations for unique applications. Such
commands, for example, allow you to enable autozero or offset
compensation, or change various analog-to-digital (A/D) converter
parameters.
Triggering the
Multimeter The multimeter’s trigger system allows it to be internally or externally
triggered. The system enables you to scan a multiplexer channel list
multiple times, or in the stand-alone configuration, take multiple readings
per trigger. An on-board timer allows you to pace measurements.
Reading Storage Readings are returned directly to the multimeter’s output buffer or are
stored in mainframe memory. The total number of readings which can be
stored (all multimeters combined) depends on the amount of memory
available. Each reading stored will consume four bytes of memory.
Saving Configurations To minimize repeated programming, up to 10 stand-alone multimeter
configurations can be saved and recalled. The configurations remain in
memory until a new configuration is saved or until power is cycled.
Electrical
Description The electrical performance of the multimeter is summarized in Table 1-1.
Refer to Appendix A for a complete table of specifications.

Physical
Description The 51⁄2- digit multimeter occupies one B-Size or one C-Size mainframe
slot. However, the faceplate of the B-size multimeter covers up an
additional slot in the B-Size mainframe. This prevents another B-size card
from being installed in the slot directly above the multimeter. An internal
installation kit, discussed in Chapter 2, enables you to install the multimeter
internal to the HP 75000 Series B mainframe. This saves two externally
accessed slots.
Input Terminals There are four input terminals on the faceplate of the multimeter
(see Figure 2-7 on page 29). The terminals, which are isolated from chassis
ground, are used to connect input signals when the multimeter is used
stand-alone.
A high-to-low TTL pulse applied to the External Trigger port externally
triggers the multimeter. The Analog Bus and Digital Bus ports allow relay
and FET multiplexers to be connected to the multimeter.

Introduction to Operation
This section contains information on checking communication between the
multimeter, mainframe, and computer. It includes information on returning
the multimeter to a known operating state should programming errors occur
or if you simply want to start over. It also shows how to send a command to
configure the multimeter and make a measurement.
Note The HP E1411B has a "Failed" annunciator and an "Access" annunciator on
the faceplate. The "Failed" annunciator turns on if the multimeter does not
properly respond during the mainframe’s power-on sequence. If this
occurs, return the multimeter to Hewlett-Packard for service. The "Access"
annunciator turns on each time the multimeter receives a command.
Multimeter Self-Test Once the mainframe completes its power-on sequence, the multimeter is
ready for use. Sending the self-test command is an easy way to verify that
you are properly addressing the multimeter. Also, the self-test is useful in
locating intermittent problems that might occur during operation. The
command used to execute the self-test is:
*TST?
You can also run the self-test by selecting “TEST” from the multimeter’s
front panel menu on the HP E1301A mainframe. Upon execution, the
self-test resets the multimeter, performs the test, and returns one of the
codes listed in Table 1-2.
The following program executes the self-test. The program assumes the
mainframe (command module for C-size systems) is at primary HP-IB
address of 09 and the multimeter is at secondary address 03. The program
also assumes an HP 9000 Series 200/300 computer is used.
10 !Send the self-test command to the multimeter.
20 OUTPUT 70903;"*TST?"
30 !Enter and display the self-test code.
40 ENTER 70903;A
50 PRINT A
60 !Reset the multimeter.
70 OUTPUT 70903;"*RST"
80 END
After the test passes, always reset the multimeter to return it to a known state.

Table 1-2. HP E1326/E1411 Self-Test Codes
Self-Test
Code Description
0 Test passed.
1 Multimeter does not respond to the self-test.
2Invalid communication between the multimeter’s two on-board processors.
3 Data line test between the multimeter and the mainframe command module failed.
4 Invalid communication between the multimeter and mainframe command module.
If self-test code 1, 2, 3, or 4 occurs, return the multimeter to Hewlett-Packard for repair.
Note If the multimeter did not respond to the self-test, the address you specified
may be incorrect. Refer to Chapter 2 in this manual and the HP VXIbus
Systems Installation and Getting Started Guide.
Resetting the
Multimeter During operation, programming errors and other conditions may occur
making it necessary to reset the multimeter. This section shows you how to
reset and clear the multimeter, and read its error queue.
The multimeter is reset with the command:
*RST
which can be sent from an HP 9000 Series 200/300 computer as:
OUTPUT 70903;"*RST"
The multimeter can also be reset by pressing the green “Reset Instr” key on
the HP E1301A mainframe front panel. Note that the multimeter must first
be selected from the mainframe menu.
When resetting the multimeter:
•A front panel reset (“Reset Instr” key on the HP E1301A mainframe)
returns the multimeter to the idle state from the busy state and sets the
multimeter’s power-on configuration (Table 1-3). A front panel reset is
equivalent to clearing the multimeter followed by a reset.
•A reset from the computer (*RST) returns the multimeter to the idle
state from the busy state if the multimeter is busy due to a command
entered from the front panel. If the multimeter is busy due to a
command sent from the computer, you must clear the multimeter
before sending the reset. The reset sets the multimeter’s power-on
configuration.

Clearing the Multimeter When the multimeter is selected from the HP E1301A mainframe menu, the
multimeter is cleared by pressing the “Clear Instr” key on the front panel.
The multimeter is also cleared by sending the following command from an
HP 9000 Series 200 or Series 300 controller:
CLEAR 70903
Clearing the multimeter:
–allows you to regain control without cycling power and without
setting the power-on configuration.
–with the HP E1301A “Clear Instr” key terminates any
command entered from the front panel. A command sent from
the computer will still continue to execute.
–from the computer (CLEAR 70903) terminates any command
sent from the computer. A command entered from the
HP E1301A front panel will still continue to execute.
–erases any pending commands. For example, if commands are
sent from the computer to the multimeter while the multimeter is
waiting for an external trigger, the commands are buffered until
they can execute after the trigger is received. Clearing the
multimeter (from the computer) erases those commands.
Similarly, clearing the multimeter from the HP E1301A front
panel erases any pending front panel commands.
–if cleared from the HP E1301A front panel, the display buffer is
cleared. If cleared over HP-IB, the data in the output buffer is
erased.
The Error Queue When an error occurs during operation, an error code and corresponding
message are stored in the multimeter’s error queue. If the Series B
mainframe has a display (HP E1301A) and the multimeter is being
monitored, the "err" annunciator will turn on.
Since many mainframes may not have a front panel display, the other way
to determine if an error has occurred is to read the error queue. This is done
with the command:
SYSTem:ERR?
The following program shows how the command is used to read and clear
the error queue.
10 !Declare a string variable in the computer to store the error message.
20 DIM Message$[256]
30 !Read the error queue until no errors remain.
40 !Print the error codes and messages.
50 REPEAT
60 OUTPUT 70903;"SYST:ERR?"
70 ENTER 70903;Code,Message$
80 PRINT Code,Message$
90 UNTIL Code=0
100 END
