CHAPTER 1

INTRODUCTION

Warning

● Read the user manual before operating and

follow all safety information.

● Only use the meter as specied in this user

manual.

● Never use this meter on a circuit with volt-

ages greater than 600Vrms @ 50/60Hz.

● Never measure current while the test leads

are connected to the input jacks.

● Do not operate the meter if the body or test

leads look damaged.

● Only use factory supplied leads.

● Check the rotary range switch and make

sure it is at the correct position before each

measurement.

● Do not perform resistance and continuity

test on a live circuit.

● Use extreme caution when measuring live

systems with voltages greater than 60VDC or

30VAC.

● Use extreme care when working around bus

bars and bare conductors.

● Do not use the meter in over range/overload

conditions (OL).

● For accurate readings, change the battery

when the symbol appears.

1.1 International Electrical Symbols

This symbol signies that the instrument is pro-

tected by double or reinforced insulation.

This symbol on the instrument indicates a

WARNING and that the operator must refer to the

user manual for instructions before operating the

instrument. In this manual, the symbol preceding

instructions indicates that if the instructions are

not followed, bodily injury, installation/sample and

product damage may result.

Risk of electric shock. The voltage at the parts

marked with this symbol may be dangerous.

1.2 Receiving Your Shipment

Upon receiving your shipment, make sure that the con-

tents are consistent with the packing list. Notify your dis-

tributor 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 descrip-

tion of any damage. Save the damaged packing container

to substantiate your claim.
