Overview HP 4338B

Overview

HP 4338B Milliohmmeter is a precise, reliable, and high speed test tool for measuring low

resistance.

Features

Low and selectable test signal current: 1Ato10mA

Wide measurement range: 10 to 100 k

10 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 oers selectable low level ac

test signals (1A to 10 mA), so now low current conditions can be characterized. A high

resolution of 10 allows you to determine the slightest dierences 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 eects 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 signicant

factor in the test, the auto measurement function allows the HP 4338B to select the

appropriate test signal level and measurement range.

Incoming Inspection

Warning

Inspect the shipping container for damage. If the shipping container or cushioning material

is damaged, it should be kept until the contents of the shipment have been checked for

completeness and the HP 4338B has been checked mechanically and electrically. The contents

of the shipment are as follows:

HP 4338B LCR Meter

Power Cable

Operation Manual(This Book)

User's Guide

If the contents are incomplete, if there is mechanical damage or defect, or if the analyzer does

not pass the power-on selftests, notify the nearest Hewlett-Packard oce. If the shipping

container is damaged, or the cushioning material shows signs of unusual stress

carrier as well as the Hewlett-Packard oce. Keep the shipping materials for the carrier's

inspection.

To avoid hazardous electrical shock, do not turn on the HP 4338B when

there are signs of shipping damage to any portion of the outer enclosure

(for example, covers, panel, or display)

, notify the

Ventilation Requirements

To ensure adequate ventilation, make sure that there is adequate clearance of at least 400 mm

behind, 100 mm sides and 15 mm above.

Instruction for Cleaning

For cleaning, wipe with soft cloth that is soaked with water and wrung tightly without undue

pressure.

Getting Started 1-9

Overview HP 4338B

Power Cable

In accordance with international safety standards, this instrument is equipped with a

three-wire power cable. When connected to an appropriate ac power outlet, this cable grounds

the instrument frame. The type of power cable shipped with each instrument depends on the

country of destination. Refer to Figure 1-1 for the part numbers of the power cables available.

Warning

For protection from electrical shock, the power cable ground must not be

defeated. The power plug must be plugged into an outlet that provides a

protective earth ground connection.
