Initial Operation

General Information The HP E1312A is not recommended for use in the HP E1300A or HP E1301A B-size mainframe.

The HP E1312A (VXI B-size) and HP E1412A (VXI C-size) Multimeters are VXIbus message-based slave devices.

Programming the multimeter can either be through a command module using an HP-IB interface or an embedded controller. You use the Standard Commands for Programmable Instruments (SCPI; see Chapter 3) with the Standard Instrument Control Language (SICL) or VISA (Virtual Instrument Software Architecture).

Maximum current is 3A ACrms or DC.

Resolution is from 4½-digits for fast measurements to 6½-digits for

more accuracy. Resolution is set by specifying the integration time in number of power line cycles (NPLCs) or corresponding aperture time. Table 1-1 shows the correlation between NPLCs and resolution.
