1. PRELIMINARY AND SAFETY
WARNING
For your own safety as well as that of the apparatus, you are recommended
to follow the procedures described in this instruction manual and carefully
read all the notes preceded by the symbol
. No compliance with the
Warnings and/or Instructions may damage the apparatus and/or its
components or injure the operator.
1.1.
Preliminary instruction

Read this instruction m
anual and the instrument’s one before starting use.

Any instruction preceded by the caution symbol must be observed in order to avoid
accidents or damages.

This product must be used only by qualified personnel practicing applicable safety
precautions, wear protective clothing and gloves as required.

Do not effect any measurement under conditions beyond the limits specified in this
manual.

Always connect electronics unit to display device before installing the flexible
measuring head.

Do not install the clamp around cables where the current flowing is greater than the
maximum measurable current (overrange).
WARNING
Hazardous potentials may exist in the vicinity of the desired current
measurements. Use locally approved safety procedures when working near
hazardous potentials. It is recommended not to install the clamp around a live
bus that is at a hazardous potential. If installation is not possible when the bus is
inactive or power is turned off, always use appropriate gloves and/or equipment
approved for working around hazardous potentials when installing the FLEX3 in
the vicinity of these hazardous potentials.
The FLEX3 transducer and interconnection cable use double insulation to protect the
operator from possible hazardous potentials of the bus. Make sure the electronics package
is well away from the bus. The current probe is rated for Installation Category III, Pollution
Degree 2. The maximum voltage to earth rating for the transducer and cable is 1000V
AC
.
1.2.
During use

Always de-energize circuit under test before installing flexible measuring head. Always
inspect the connecting cable and flexible measuring head for damage before using this
product.

Do not use product if damaged.

Do not use the clamp on non-insulated conductors whose potential to earth exceeds
1000V and for frequencies over 5kHz.

Do not use the clamp outdoor.

Do not use the clamp at altitudes exceeding 2000 meters.

Do not expose the clamp to water splashes.

Keep the clamp gap perfectly clean.
