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 5
1
⁄
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.
