PRECAUTIONS FOR USE
The protection assured by the current sensor can be compromised if it is used in a
way that is not recommended by the manufacturer.
Comply with the rated maximum voltage and current and the measurement cat-
egory. Do not use your current sensor on networks where the voltage or category
exceeds those stipulated.
Comply with the conditions of use, that is to say temperature, humidity, altitude,
degree of pollution and location of use.
Do not use the current sensor if its housing is open, deteriorated, or incorrectly
reassembled. Before each use, check the integrity of the insulation of the core or
of the arms of the clamps, of the housing, and of the leads.
Do not subject the current sensor to sprayed or falling water or other liquids.
Keep the gap of the clamp absolutely clean.
Use suitable personal protective equipment when parts at hazardous voltages may
be accessible in the installation where the measurement is made.
Any repairs must be carried out by accredited skilled personnel.

2. USE
Current clamps, MiniFlex® and AmpFlex® exible current sensors are used to measure
the current owing in a cable without opening the circuit. They also insulate the user
from dangerous voltages in the circuit.
The choice of current sensor to be used depends on the current to be measured
and the diameter of the cables.

* : The measurement ranges are those of the sensors. In some cases, they may differ
from the ranges that can be measured by the analyser with which they are associated.
For three-phase measurements, start by marking the accessories using the col-
oured rings supplied with the device: a different colour for each current terminal.
Connect the current sensors to the current terminals of the device.
For the PAC93:
Set the switch to “1 mV/A”; the “ON” indicator lights.
Once the PAC93 is connected to the device, adjust the zero by turning the poten-
tiometer with no conductor in the jaws of the clamp.
93
At the end of the measurement, remember to switch off the PAC93.

For the clamps:
Press the trigger on the clamp to open the jaws.
Then clamp the cable that is to be measured. Where possible, the cable should
be centred in the jaws of the clamp.
I
Release the trigger.
For the MiniFlex® models:
Press on the yellow opening device to open the exible coil.
Open it and place it around the conductor carrying the current to be measured
(only one conductor in the sensor). Where possible, the cable should be centred
in the sensor.


or
Close the coil. You must hear the click.
For the AmpFlex® models:
Press simultaneously on both sides of the opening device.
Then clamp the cable that is to be measured. Where possible, the cable should
be centred in the sensor.
14

31
Close the sensor by forcing the moving part into the connector until you hear a click.
For details of the measurement conguration and technical characteristics,
refer to the user manual of the analyser with which you are using the current
sensor.

4. MAINTENANCE
Except for the batteries, the instrument contains no parts that can be
replaced by personnel who have not been specially trained and accredited.
Any unauthorized repair or replacement of a part by an “equivalent” may
gravely impair safety.
4.1. CLEANING
Disconnect the current sensor completely.
Use a soft cloth, dampened with soapy water. Rinse with a damp cloth and dry
rapidly with a dry cloth or forced air. Do not use alcohol, solvents, or hydrocarbons.
Keep the air gaps of the clamps perfectly clean.
See to it that no foreign body interferes with the operation of the snap lock device
of the sensor.
4.2. REPLACING THE BATTERY OF THE PAC93
Disconnect the PAC93 completely and turn the rotary switch to OFF.
Turn the PAC93 over.
Use a screwdriver to unscrew the screws and remove the battery compartment
cover.
Withdraw the battery from its compartment without pulling on the wires.
18

35
Disconnect the old battery without pulling on the wires and connect the new one
in its place, observing the polarity.
Spent batteries must not be treated as ordinary household waste. Take them
to the appropriate recycling collection point.
Put the battery into its compartment.
Put the cover back in place and screw the screws back in.
5. WARRANTY
Except as otherwise stated, our warranty is valid for twelve months starting from
the date on which the equipment was sold. Extract from our General Conditions of
Sale provided on request.
The warranty does not apply in the following cases:
Inappropriate use of the equipment or use with incompatible equipment;
Modications made to the equipment without the explicit permission of the manu-
facturer’s technical staff;
