Note:
A. At range 200Ω, short-circuit the test leads to measure the resistance of the wire, then subtracts

** it from the real measurement.
B. At range 200 MΩ, when the test leads short circuit, LCD displays 1.0 MΩ. In the same way, the reading 

** is 10 MΩ while the test leads short at range 2000 MΩ. It’s normal and does not affect the accuracy. 
** Please deduct the value from the real measurement.
C. The reading will be displayed slowly when the measurement is more than 1 MΩ. Please wait until stable.
