1. GENERAL INSTRUCTIONS

1.1. Precautions and safety measures

1.1.1. Before using

You have just acquired a 4,000-count multimeter clamp. We
thank you for your confidence.
This multimeter clamp complies with the IEC 61010 norms
concerning electronic measuring instruments. For your own
safety and to prevent damage to the instrument, you must
follow the instructions given in this manual.

∗ This instrument can be used for measuring category III

installation circuits, in an environment with a pollution
degree of 2 and with a voltage no higher than 600 V in
relation to the earth.

∗ Definition of the installation categories

(see IEC 61010-1 publication):
CAT I: CAT I circuits are circuits protected by low level

transient -voltage surge limiters
Example: protected electronic circuits

: CAT II circuits are household or similar appliance

CAT II
power circuits, which may carry medium-level transient
voltage surge.
Example: household appliance and portable tool power
supplies

CAT III : CAT III circuits are high-power appliance power
circuits, which may carry high-level transient voltage
surges.
Example: industrial machinery or instrument power
supplies

CAT IV : CAT IV circuits are circuits which can carry very
substantial transient -voltage surges.
Example: power feeders

For safety reasons, you should only use leads that comply with
the IEC 61010 standard.
Before using, always check that they are in perfect working
order.

1.1.2. When using the instrument

• Never exceed the protection limit values indicated in the

specifications for each type of measurement.

• When the multimeter clamp is linked to the measurement

circuits, do not touch any unused terminals.

• Before changing the function, disconnect the measure-

ment leads from the circuit measured.

• Never measure resistances on a live circuit.

1.1.4. Instructions

• Before opening the instrument, disconnect it from the
measuring circuits and make sure that you are not charged
with static electricity, which could irreparably damage the
instrument's internal elements.

• A "qualified person" is someone who is familiar with
the installation, the construction, the application and the
dangers at hand. This person is authorised to power up and
power down the installation and equipment, in compliance with
safety regulations.

1.1.5. Cleaning

Turn off the power supply. Clean with a damp cloth and soap.
Never use abrasive products or solvents.

1.2. Warranty

This equipment is guaranteed against any material or
manufacturing defects, in accordance with the general
conditions of sale.
During the warranty period (1 year), the instrument can only be
repaired by the manufacturer, who reserves the right to repair
the instrument or to exchange all or part of it. If the equipment
is returned to the manufacturer, the outgoing transport costs
are borne by the customer.

The warranty is not applicable in the following cases:

1. improper use of the equipment or use of it in conjunction
with incompatible equipment;

2. modifications to the equipment without the explicit
authorisation of the manufacturer's technical department;

3. work carried out on the instrument by a person not
approved by the manufacturer;

4. adaptation for a specific application, not included in the
definition of the equipment or the user's manual

5. knocks, falls or flooding.

The contents of this manual must not be reproduced in any
form without our consent.

1.3. Maintenance

Return your instrument to your distributor for any work to be
done within or outside the guarantee.

1.4. Unpacking - Repacking

All the equipment was checked mechanically and electronically
before shipment. Every precaution was taken to ensure that
you receive the instrument undamaged. It is a good idea to
check quickly to detect any damage that may have occurred
during transport. If there is any damage, immediately notify the
transporter of the customary reservations.

Caution! If you ship this instrument on elsewhere,
use preferably the original packaging and indicate the
reasons for reshipment as clearly as possible in a note
enclosed with the equipment.
