Description
The Agilent Technologies E1412A
6.5-Digit Multimeter is a C-size,
1-slot, message-based VXI module.
It is identical in electrical design
to the E1312A, differing only in
size. It delivers the widest functionality in Agilent’s DMM line.
It also delivers high performance
and Agilent 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- and 4-wire Ω,
plus frequency/period. When
measuring dcV, this multimeter
can deliver 65 range changes
per second and 30 function
changes per second.

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.
