except current measurements.

7. Rotary Switch: Turn to power the meter on and off and select the desired

measurement function. To save battery power, turn to the

“OFF”

position when

the meter is not in use. See

“ROTARY SWITCH”

section for function descriptions.

8. MAX/MIN Button: Press to enter or exit the Min/Max recording mode.
