back to zero , enter into relative

measurement ,LCD display “

” symbol, press it again, out from

the relative value measurement

function .when at Hz range, can

switch to frequency or duty cycle

(0.1~99.9%) measurement mode.

2. ANGE key :selecting operation

mode of auto range or manual

range .the default mode of this

meter is auto range , LCD display“

” symbol, press this key will

change to manual range, press it

3

one more time to increase a new

range, from low to high cycle in

turn .press the key for more than 2

seconds, will back to auto range

mode.
