10 µΩ resolution
1 kHz ac measurement
High speed measurement: 34 ms
Built-in comparator
Auto measurement mode

■	Precise Low Resistance Measurement

Contact failure of electro-mechanical components in
low current circuits is a key issue in determining
these components’ reliability. The HP 4338B offers
selectable low level ac test signals (1 µA to 10 mA),
so now low current conditions can be characterized.
A high resolution of 10 µΩ allows you to determine
the slightest differences in contact resistance testing
of relays, switches, connectors, PC board traces, and
cables. The 1 kHz test signal eliminates potential
errors introduced by thermo-electric effects across
the DUT contacts. The 1 kHz ac test signal is the
best solution for evaluating the internal resistance
of batteries because it avoids dc energy consumption.

■	High Speed Measurements

The high speed (34 ms), built-in comparator, and
HP-IB/handler interfaces makes it possible to construct
a measurement system using an automatic handler and
an external computer to minimize production test time.

■	Auto Measurement Mode

When performing gross continuity testing where the
test signal level is not a significant factor in the
test, the auto measurement function allows the HP 4338B
to select the appropriate test signal level and measurement
