4. Do not input a current with an effective value higher than 600uA,
otherwise there is a risk of damaging the instrument.
A current
1. Insert the red probe into the " " jack and the black probe into the
jack.
2. Turn the knob switch to the " " position and press the key to switch
the AC current, DC current or frequency measurement.
3. Connect the measurement probe in series to the load, and the polarity of the red
probe connection will be displayed when the current value is displayed.
Warning：
1. Before turning the function rotary switch, leave the measurement probe
from the circuit under measurement.
2. When the screen only displays "OL", it means that the range has been
exceeded and the measurement shall be terminated.
3. Do not input a voltage with an effective value higher than 0V, otherwise
there is a risk of damaging the instrument.
4. Do not input a current with an effective value higher than 600uA,
otherwise there is a risk of damaging the instrument.
