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