WARNING
The voltage above 250V can’t be measured; otherwise the instrument
may be damaged.
Pay special attention to safety when measuring high voltage to avoid
electric shock or personal injury.
Test the known current with the meter before use; confirm the instrument
function is intact.
When measuring large current, continuous measurement should be no
longer than 15 seconds
Caution
To avoid damaging the instrument or equipment, check the fuse before
measuring and ensure that the measured current does not exceed the
rated maximum current; use the correct input.
