GOM-802 DC MILLI-OHM METER

USER MANUAL

⎯ ⎯

This cable/appliance should be protected by a suitably rated and

approved HBC mains fuse: refer to the rating information on the

equipment and/or user instructions for details. As a guide, cable of

0.75mm

should be protected by a 3A or 5A fuse. Larger conductors

would normally require 13A types, depending on the connection

method used.

Any mounded mains connector that requires removal /replacement

must be destroyed by removal of any fuse & fuse carrier and disposed

of immediately, as a plug with bared wires is hazardous if a engaged

in live socket. Any re-wiring must be carried out in accordance with

the information detailed on this label.

1. PRODUCT INTRODUCTION

1-1. Description

GOM-802 is a high precision programmable DC Milli-ohm meter suitable

for the low resistance measurements of switches, relays, connectors, PCB

tracks and variety of other devices. With the easy-to-use features, superior

performance, and automatic test interfaces described as below, GOM-802 is

obviously a reliable and handy instrument for the low resistance

measurements.

Easy-to-use features:

Utilizing the arrow key for setting the percentage of upper and lower limit based on

the normal value can make it easier to execute the HI-LO-GO

comparator

function.

Besides, through the Alarm Buzzer setting can indicate the PASS/FAIL status, and

all kinds of output status can be indicated through Handler Interface output.

The RELATIVE feature that enables GOM-802 to remove the stray resistance easily,

and the 20 sets of Normal/Hi/Lo setting memories can satisfy with different kind of

test condition. Also, the last setting will be recalled every time when the GOM-802

is turned on.

Superior Performance:

There are nine measurement ranges from 30mΩ to 3MΩ selected automatically or

manually with the constant current between 1μA and 1A, 0.05% high accuracy,

1μΩ resolution and four terminals Kelvin connection to make a reliable and

consistent test result.

The flexible choice for a high measurement accuracy at speed of 7 sampling/sec

(full scale at 30000) or a less measurement accuracy at speed of 30 sampling/sec

(full scale at 3000) can match with the speed requirement of test.
