•  When  the  resistance  above 1MΩ  is  measured,  the 

reading  on  the  meter  will  not  be  stable  until  several 

seconds have passed. This is normal for high-resistance 

measurement. 

• When the resistor is measured, do not input voltage 

value.  Never  input  the  voltage  above  the  overload 

protection, otherwise, the meter may be damaged and 

the operator may be hurt. 

•  After  the  measurement  is  over,  immediately 

disconnect the test probe from the tested circuit.
