The HP E1312A 6.5-digit multimeter is a B-size, 2-slot, message-based VXI module. It is identical in electrical design to the HP E1412A, differing only in size. It delivers the widest functionality in HP’s DMM line. It also delivers high performance and HP high quality at prices you’d expect to pay for a 5.5 digit DMM.
This multimeter’s wide product functionality includes volts, amps,
ohms, and frequency with advanced tests including limit checks to
drive a TTL output and dc voltage ratios. Standard measurements
include AC/DC voltage, AC/DC current, 2- & 4-wire Ohm, plus
frequency/period. When measuring DCV, this multimeter can deliver
65 range changes/sec and 30 function changes/sec.
Note: Configuration software that allows you to easily select
compatible interfaces, controller platforms, and VXI test system
components is available on CD ROM. Order the
"Test System
and VXI Products Catalog and CD ROM" from
the Test & Measurement Catalogs available on this web site.

Measuring Characteristics
Measurement Method: Reciprocal-counting technique. AC-coupled input using the AC voltage measurement function. Voltage Ranges: 100 mV rms full scale to 300 V rms. Auto or manual ranges. Gate Time: 10 ms, 100 ms, or 1 s Settling Considerations: Errors will occur when attempting to measure the frequency or period of an input following a dc offset voltage change. The input blocking RC time constant must be allowed to fully settle (up to 1 s) before the most accurate measurements are possible. Measurement Considerations: All frequency counters are susceptible to error when measuring low-voltage, low-frequency signals. Shielding inputs from external noise pickup is critical for minimizing measurement errors.
