Thank you for purchasing a Model 603 Clamp-on Meter.

For best results from your instrument and for your safety, read the enclosed
operating instructions carefully an d comply with the precautions for use. These
products must be only used by qualified and trained users.

Meanings of the symbols used on the device

CAUTION - Risk of Danger! Indicates a WARNING and that the operator

must refer to the user manual for instructions before operating the
instrument in all cases where this symbol is marked.

Risk of electric shock. The voltage at the parts marked with this s ymbol
may be dangerous.

Refers to a type A current sensor. This symbol signifi es that application
around and removal from HAZARDOUS LIVE conductors is permitted.

1.5 V battery

The CE marking indicates compliance with European directives

PRECAUTIONS FOR USE

This device complies with safety standards IEC-61010-1 and 61010-2-032 for voltages of
1000V in category IV at an altitude of less than 2000m, indoors, with a degree of pollution
not exceeding 2.
These safety instructions are intended to ensure the safety of persons and proper operation
of the device.

 The operator and/or the responsible authority must carefully read and clearly

understand the various precautions to be taken in use.

 If this ins trument is used other than as specified, the protection it provides may be

compromised, thereby endangering you.

 Do not use the instrument in an explosi ve atmos phere or in the pres ence of fl ammable

gases or fumes.

 Do not use the instrument on networks of which the voltage or category exceeds those

mentioned.

 Do not exceed the rated ma ximum voltages and currents between terminals or with

respect to earth.

 Do not use the i nstrument if it appears to be damaged, incomplete, or not properly

closed.

 Before each use, check the condition of the insulation on the leads, housing, and

accessories. Any element of which the insulation is deteriorated (even partiall y) must
be set aside for repair or scrapped.

 Use leads and ac cessories rated for voltages and categories at least equal to those of

the instrument. If not, an accessory of a lower category lowers the category of the
combined Clamp + accessory to that of the accessory.

 Observe the environmental conditions of use.
 Do not modif y the instrument and only use factory replacement parts. Repairs and

adj

ustments must be done by approved qualified personnel.

 Replace the batt eries as soon as the symbol app ears on the display of the unit.

Disconnect all leads before opening the battery compartment cover.

 Use personal protective equipment when conditions require.
 Keep your hands away from the unused terminals of the instrument.
 When handling the tes t probes, alligator clips, and clamp ammeters , keep your fingers

behind the physical guard.

 As a safety measure, and to avoid repeated overloads on the inputs of the device,

configuration operations should only be performed when the device is disconnected
from all dangerous voltages.

2 THE BUTTONS

The buttons respond differently to short, long, and sustained presses.
The , and keys provide additional functions as well as the
detection and acquisition of parameters complementary to the basic
measurements.

• Each of these buttons can be used independently of the others or in
conjunction with each other. T his makes navigation simple and intuit ive
when reviewing measurement results.

• It is possible, for example, to either look up in turn s equence the MAX,
MIN, etc. values of the RMS voltag e alone, then display relat ive values
in parallel

In this section, the icon represents the possible positions of the s witc h for the
button’s functionality.

2.1

BUTTON

This button is used to:

 Store and look up the last values acquired specif ic to each function (V, A,

Ω, T°, Adp) according to the spec ific m od es prev ious l y ac ti v ated (M A X/MIN,
Hz, ΔREL). The present display is then maintain ed while the detection and
acquisition of new values continues.

 Perform automatic lead resistance compensation (see § 3.6.1).
 Perform automatic zero correction in A

It can also be used to modify the default values in the configuration mode
(see § 3.4).
