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 (100A) 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
conductors under test
3. Connect clamp's output terminal to the inputs of the instrument to be used as indicator
4. Select the 10A or 100A desired range on clamp. The yellow LED "ON" should be on. Verify that "Low Bat" red LED
it's off. If no, open the back battery cover and replace the batteries.
5. Verify the zero at display of instrument to be used as indicator. If no, press ZERO key on clamp before start
measurement
6. Open the clamp and put the tested conductor in the centre of the clamp jaws. No gap is allowed between the
connections of clamp jaws. Always consider the correct connection of clamp (see above picture)
7. 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
