IMPORTANT SAFETY INFORMATION
•
When using electrical appliances basic safety precautions should always be
followed.
•
Check the clamp ammeter and test pen before use. If there is any damage or any
abnormalities, do not use it.
•
Do not use the clamp ammeter if the battery cover and rear cap is not in place, as
there is a risk of electric shocking.
•
Keep fingers within the scope of the test pen finger protection. Do not contact the
bare wire and connector, the unused input terminal or the circuit being measured
when the clamp ammeter is in operation.
•
Ensure that function switches are set at the correct position prior to measurement.
Do not perform gear conversion in measurement to guard against damage to the
meter.
•
Do not apply over 1000VDC or 750VAC between the clamp ammeter terminals
and ground, to guard against damage to the meter.
•
Be careful in measuring RMS voltage higher than 30V DC or AC, as there will be
electric shocking.
•
Do not measure voltage or current higher than the allowable input value. Set the
function range switch at the maximum range position if the scope of the measured
value cannot be defined.
•
Before measurement of online resistance and diode or circuit on-off measurement,
the power to the circuits being measured must be switched off and all capacitors
should be completely discharged to assure measurement accuracy.
•
When the LCD displays the low battery symbol, replace the battery immediately in
order to ensure measurement accuracy.
•
Remove the battery when the clamp meter is not in use for a long period of time.
•
Do not change the internal wiring in the clamp ammeter, in order to guard against
damage to the meter.
•
Do not store or use the clamp ammeter in an explosive or flammable environment
with high temperature, high humidity or a strong electromagnetic field.
•
Clean the clamp meter case with a soft cloth and a neutral detergent.
•
Do not use any chemicals, abrasives or solvents to avoid causing damage to the
instrument.
