1. INTRODUCTION

Thank you for purchasing an AEMC®Instruments Megohmmeter Model 1015.

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

Signies that the instrument is protected by double or reinforced insulation

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

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

Indicates a risk of electric shock. The voltage at the parts marked with this

symbol may be dangerous

Important information to acknowledge

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 installa-

tion at the distribution level.

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

CAT II corresponds to measurements performed on circuits directly con-

nected to the electrical distribution system.

Example: measurements on household appliances and portable tools.

Megohmmeter Model 1015

1.1 PRECAUTIONS FOR USE

These safety warnings are provided to ensure the safety of personnel and

proper operation of the instrument.

Read this instruction manual completely and follow all the safety

information before attempting to use or service this instrument.

Safety is the responsibility of the operator!

Tests are to be carried out only on dead circuits! Check for live circuits

before making resistance measurements (safety check).

Always make connections from the instrument to the circuit under test.

These megohmmeters are sources of high voltage, as is the sample

connected to them. All persons performing or assisting in the tests must

follow all safety precautions to prevent electrical shock to themselves

and to others.

AEMC considers the use of rubber gloves to be an excellent safety

practice even if the equipment is properly operated and correctly

grounded.

When testing capacitance samples, make sure that they have been

properly discharged and that they are safe to touch. Dielectric insulation

samples should be short-circuited for at least ve times the amount of

time they were energized.

Never open the back of the instrument while connected to any circuit or

input.

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 car-

rier and notify your distributor at once, giving a detailed description of any

damage. Save the damaged packing container to substantiate your claim.

2. PRODUCT FEATURES

2.1 DESCRIPTION

The Megohmmeter Model 1015 is a True Megohmmeter®analog instru-

ment with four easy-to-read scales.

The MΩscale is an easy-to-read log scale graduated from 0.1 to 1000

MΩ(yellow background) at 500 V and 1000 V. The Ωscale is linear with a

range from (0 to 10) Ω(white background).

To use the (0 to 1000) Ωscale, take the reading on the (0 to 10) Ωrange

and multiply the reading by 100. The AC voltage scale is linear with a

range of (0 to 600) VAC (white background). Continuity tests are done with

a test current of 200 mA.

The colored battery scale has a range of green for a good battery and a

range of red or lower for a defective battery.

A built-in battery tester is provided by simply pressing the yellow push

button when the selector switch is in the OFF position.

Voltmeter (safety check) with a range of (0 to 600) VAC is standard and

works when the selector switch is in the 500 V position or the 1000 V posi-

tion.

2.2 FEATURES

• Measures insulation at 1000 V

• (0 to 1000) Ωresistance range

• Push button for battery check

• Designed for harsh environments: o󰀨shore, mining, heavy-duty eld,

industrial, commercial electrical and military use

• (0 to 10) Ω+ and (0 to 10) Ω- continuity ranges

• Continuity 200 mA test current

• Small and lightweight

• Large, direct-reading, colored scale

• 600 V test voltage range (safety check)

• Yellow non-slip shockproof case

• True Megohmmeter®
