Specifications; Measurement Procedure - HT HT4003 Bedienungsanleitung

USER MANUAL

This note must be read in full. Any operations on live conductors can be dangerous.

The operator is expected to be fully aware of all necessary electrical safety regulations and
procedures. Safe operation is this responsibility.

Never exceed the limit of Voltage (600V) or current (400A) indicate in this manual.

When measuring current, if strong current nears to the clamp jaw, it will affect the
accuracy.

While measuring current, always put the tested conductor in the center of clamp jaw so as
to obtain a more accurate reading.

It is up to the user to ensure that the equipment is at all times in its original safe conditions.

Strong vibrations and impacts may cause damage to the instrument..

MEASUREMENT PROCEDURE

1. Before start the test, take all precautionary measures for operator's safety (electrical protection gloves,
etc.).
2. Even if it is possible to insert / remove energized conductors from the jaws (symbol
possible) the conductors under test.
3. Connect clamp's output terminals to the inputs of the instrument to be used as indicator.
4. Open the clamp and put the tested conductor in the center of the clamp jaws, (no gap is allowed between
the connections of clamp jaws).
5. Read the current value in the indicator's display.
CAUTION: this symbol indicates that equipment and its accessories shall be subject to a
separate collection and correct disposal.
