[1] The rotary switch position is only for specific models.
[2] When measuring current, for 10 A to 15 A, the measuring duration should not be over 2
minutes within 10 minutes, and in this 10 minutes, no other current should flow through
except within the measuring duration; for 15 A to 20 A, the measuring duration should not be
over 10 seconds within 15 minutes, and in this 15 minutes, no other current should flow
through except within the measuring duration.
[3] When measuring capacitance, for the 20.00mF range, the measuring duration should be over
30 seconds.
[4] When measuring frequency, the typical waveform is Square or Sine. The signal meets the
following conditions.
[5] When measuring duty cycle, the typical waveform is Square.
Note: when measuring resistance and capacitance, the influence of the resistance reactance of
the pen itself on the measured value should be considered.
other current should flow through except within the measuring duration.
