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 (1000A AC/DC) 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. Connect clamp's output terminal to the inputs of the instrument to be used as indicator
2. Press and hold the ON/OFF selector on "Test" position for 10s and verify the red LED on. Replace the battery (see Fig. 2) if the
red LED is off. In the event that the LED is turned on for less than 10s are not guaranteed 72 hours of operation
3. Power on the meter by move the selector on "On" position. The red LED should be fixed on. Verify the zero at display of
instrument to be used as indicator. If no move ZERO regulation trimmer on clamp before start the measurement
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. Always consider the correct connection of clamp (see Fig. 1)
5. Read the current value in the indicator's display. Turn off the meter at the end of measurements
CAUTION: this symbol indicates that equipment and its accessories shall be subject to a separate
collection and correct disposal

Fig. 2: Battery replacement operation
Consider the herewith steps to replace internal battery (for
voltage <6V) (see Fig. 2):
1. Perform a little pressure on the hole on the top of battery
cover by using e.g. a small screwdriver
2. Shift and detach the battery cover
3. Remove the battery and replace with a same type new one
considering the correct polarity which is shown on clamp
handle
4. Replace with a click the battery cover
