SAFETY PRECAUTIONS!

1 – 0

The following safety precautions must e o served during all phases of operation, service, and

repair of this instrument. By purchasing this equipment the purchaser assumes all lia ility for the

operation and use of this equipment. The intended use of the instrument, its design and

manufacture, is to e conducted within the precautions or other specific warnings located within

this manual. Failure to comply with these precautions and other specific warnings violates safety

standards of design, manufacture, and intended use. Raytech assumes no lia ility for the

operation and use of this equipment.

SAFE OPERATION

Only qualified knowledgea le persons should e permitted or attempt to operate this test

equipment. All test personnel should fully familiarize themselves with the correct application and

operation of this and all test equipment prior to operation. Persons directly and indirectly

engaged in the operation of this test equipment should keep clear of all high voltage apparatus

while conducting tests and measurements.

BEFORE APPLYING POWER

Read this manual carefully efore operating the system. The Micro Junior 2 is attery operated.

The attery pack is charged via an external power supply which can handle input voltage from

100 to 240 vac 50/60Hz (auto-sense).

DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE

Do not operate the instrument in the presence of flamma le gases or fumes.

KEEP AWAY FROM LIVE CIRCUITS

Operating personnel must not remove instrument covers. Component replacement and internal

adjustments must e made y qualified service personnel. Do not replace components with

power ca le connected. To avoid injuries, always disconnect power, discharge circuits, and

remove external voltage sources efore touching components.

DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT

Because of the danger of introducing additional hazards, do not install su stitute parts or perform

any unauthorized modification to the instrument. Return the instrument to a Raytech USA

service department for service to ensure proper operation and that safety features are maintained.

Instruments, which appear damaged or defective, should e made inoperative and secured against

unintended operation until they can e repaired y qualified service personnel.

TEST WARNINGS!

1. Do not use on live circuits.

2. Do not use test probes when testing inductive loads (Motors, transformers).

1. The Micro Junior 2 Fieldcase is a waterproof design that may incorporate a pressure relief valve. This

valve should e slightly open when encountering atmospheric changes; i.e... Airplane Travel, High

altitudes, etc... Close the valve when transporting the equipment in wet conditions.

INTRODUCTION 3 – 0

Raytech Digital Micro ohm meter, Micro Junior 2 was designed for high degree of accuracy for

the measurement of very low resistance. This technology was then packaged into a porta le test

system for use y apparatus manufacturers, re uild shops, and electrical maintenance crews.

Ease of use: This intelligent system has an easy to use operation screen, which allows quick

selection of the current level and resistance level to e measured. The system has the a ility to

reverse current flow automatically and provide extremely accurate results.

Impressive Accuracy: The Micro Junior 2 is a high precision, fully automatic, microprocessor

ased system. This system is designed for highly accurate readings on-site with la oratory precision.

Unique Measuring Technique: This newly designed technique of measurement incorporates a

high precision measurement circuit which will automatically measure with current flow in one

direction, then the system will reverse the current flow and display very accurate results to 0.1µ

Ohm. The system allows long term measurements at 10 amperes without frequent recharging.

Operation: The Micro Junior 2 applies a preset current level and resistance range selected y the

user. The results of the test are displayed within a few seconds automatically. The results are

reported on the easy to read liquid crystal display.

Compact Design: The Micro Junior 2 is a lightweight system that comes complete with its own

rugged waterproof Fieldcase.

Simple Maintenance: There is No maintenance required. There is No cali ration procedure (No

potentiometers to turn). This is due to the utilization of high precision components in the design.

Advanced Protection: Upon powering on the system initializes itself with a self-cali rating,

circuit checking sequence. If any pro lems are detected during this initialization period, or

during operation, the operator is immediately notified. The system constantly monitors the

condition when turned on. The Micro Junior 2 has extensive protection uilt in to the circuitry.

This is one of the many reasons we can extend our warranty to 5 years.
