1.1. DURING USE
Always keep to the instructions contained in this manual:
•
Before changing the switch position, take off the clamp jaw from
the tested conductor or the electrical circuit to avoid any accident
•
When the clamp is connected to the circuits to be tested, never
touch unused terminals
•
When testing resistors, do not add voltage. Although there is a
protection circuit, excessive voltage would cause malfunctioning
•
Before measuring current, remove the voltage-resistance test
leads
•
When measuring current, any strong current close to the clamp
jaw will affect the accuracy
•
When measuring current, always put the tested conductor in the
middle of the clamp jaw to obtain a more accurate reading
•
If the reading value or the sign indication remains unchanged
during the measurement, check if the HOLD function is active
Noncompliance
instructions may damage the tester
components or injure the operator
1.2. AFTER USE
•
Once the measurements are completed, turn the rotary switch to
OFF.
•
If you expect not to use the clamp for a long time, remove the
battery
