Thank you for purchasing a Model 605 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 symbol may
be dangerous.

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

1.5 V battery

The CE marking indicates compliance with European directives

Double insulation or reinforced insulation

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 flammable

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

adjustments 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.

MEASUREMENT CATEGORIES

Definitions of the measurement categories:

CAT IV: Circuits supplying the low-voltage installation of the building.
Example: power lines, meters, and protection devices.

CAT III: Power supply circuits in the installation of the building.

Example: distribution panel, circuit-breakers, fixed industrial machines or
devices.

CAT II: Circuits directly connected to the low-voltage installation.

Example: power supply to household electrical appliances and portable tools.

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, file 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.

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. This makes navigation simple and intuitive
when reviewing measurement results.

 It is possible, for example, to either look up in sequence the MAX, MIN, etc.

values of the RMS voltage alone, or look up in sequence all of the MAX (or
MIN, or PEAK) values of all power measurements (W, VA, var, etc.).

In this section, the icon represents the possible posit i ons of the switch for the
button’s functionality.
