Max measuring voltage drop：200mV.
Max Input current: 20A (less than 10 seconds).
Overload protection：0.2A/250V fast-blow fuse, 20A/250V
quick-action fuse for range 20A.
Frequency response: 40Hz-200Hz.
Display: Sine wave RMS (AVG value response).

Open voltage: less than 3V.
Overload protection: 250V DC or AC peak value.
NOTE:
1. At 200Ω range, the test leads should be short-circuited, and
measure the lead to lead resistance, then, subtract from the
real measurement.
2. It is normal to display 10MΩ when the test leads shorted in
range 2000MΩ, it will not effect the accuracy and shall be
subtracted from the value measured. For example: The object
resistance is 1000MΩ, the reading value is 1010MΩ, then the
correct value shall be 1010-10=1000MΩ
3. Lagged display of value is normal when measuring
resistance higher than 1MΩ. Please wait until the display is
stable.
