Protective FunctionAnalog Multimeter

There is no OFF position on the dial knob, how do I turn off the multimeter?

When the instrument needs to be shut down after use, or when it is not used for a long time, please set it to the three settings of "AC voltage" or "DC voltage" or "DC current".
No battery power is consumed when the dial is turned to these positions.
However, if the knob is in the "resistance position" or other positions, although it has not been tested and used, it will still consume a certain amount of battery power, just like turning on the TV but not watching it will waste power.
