1. INTRODUCTION

Thank you for purchasing an AEMC®Instruments Ground Tester Model 6422 or

6424.

For the best results from your instrument and for your safety, you must read the

enclosed operating instructions carefully and comply with the precautions for use.

Only qualied and trained operators should use this product.

Symbols and Denitions

CAUTION - Risk of Danger! Indicates a WARNING. Whenever this symbol

is present, the operator must refer to the user manual before operation

CAUTION - Indicates a risk of electric shock. The voltage at the parts

marked with this symbol may be dangerous

Indicates important information to acknowledge

Ground/Earth

Current Clamp

The product has been declared recyclable

Battery

This product complies with the Low Voltage & Electromagnetic Compatibility

European directives (73/23/CEE & 89/336/CEE)

In the European Union, this product is subject to a separate collection

system for recycling electrical and electronic components in accordance with

directive WEEE 2002/96/EC

Denition of Measurement Categories (CAT)

CAT IV corresponds to measurements performed at the primary electrical supply

(< 1000 V).

Example: primary overcurrent protection devices, ripple control units, and

meters.

CAT III corresponds to measurements performed in the building installation at the

distribution level.

Example: hardwired equipment in xed installation and circuit breakers.

CAT II corresponds to measurements performed on circuits directly connected to

the electrical distribution system.

Example: measurements on household appliances and portable tools.

Ground Resistance Testers Models 6422 & 6424

1.1 PRECAUTIONS FOR USE

This instrument is compliant with safety standard IEC 61010-2-030 for voltages

up to 600 V in category IV. Do not use the instrument for measurements on

circuits that are not in measurement categories II, III, or IV or that might be

connected inadvertently to circuits that are not in measurement categories II, III,

or IV.

The operator and/or the responsible authority must carefully read and

clearly understand the various precautions to be taken in use. Sound

knowledge and a keen awareness of electrical hazards are essential when

using this instrument.

If you use this instrument other than as specied, the protection it provides

may be compromised, thereby endangering you.

Do not use the instrument on networks of which the voltage or category

exceeds those mentioned.

Do not use the instrument if it seems to be damaged, incomplete, or poorly

closed.

Before each use, check the condition of the insulation on the leads,

housing, and accessories. Any item of which the insulation is deteriorated

(even partially) must be set aside for repair or scrapping.

Before using your instrument, check that it is perfectly dry. If it is wet, it must

be thoroughly dried before it can be connected or used.

The use of leads (or accessories) of a lower voltage or category limits the

voltage or category of the combined instrument and leads (or accessories)

to that of the leads (or accessories).

Use personal protection equipment systematically.

When handling the leads, test probes, and alligator clips, keep your ngers

behind the physical guard.

All troubleshooting and metrological checks must be performed by

competent and accredited personnel.

1.2 RECEIVING YOUR SHIPMENT

Upon receiving your shipment, make sure that the contents are consistent with

the packing list. Notify your distributor of any missing items. If the equipment

appears to be damaged, le a claim immediately with the carrier and notify

your distributor at once, giving a detailed description of any damage. Save the

damaged packing container to substantiate your claim.
