Input Impedance: 10MΩ .
Overload Protection: 1000V DC or 750 AC peak value.
Frequency Response: (50~200) Hz
Display: Average value response (RMS of sine wave).
2-2-3. DCA
A) Insert the black test lead into the “COM” input terminal and
red test lead into the “mA “ input terminal. (Max 400mA), or
“10A “input terminal (Max 10A).
B) Rotate function switch to Current setting. The initial state of
the meter is in automatic range status, which shows “DC”
symbol. Then connect the test lead to the tested circuit in
serial, the tested current value and the current polarity of the
point where the red pen is contacted will be displayed on the
screen simultaneously.
Caution:
1. If “OL” is displayed on LCD, it indicates the tested current
value has exceeded the present range limit, please select
higher range to complete the measurement.
2. The Max input value is 400mA or 10A. (Depending on the
terminal where the red test lead is contacted)

Max measurement voltage drop: Full Range mA is 0.4V, A is
100mV;
Max input current: 10A (less than 15 seconds);
Overload Protection: 0.4A/250V resettable fuse, 10A/250V
fuse.
