Relative Measurement; Data Hold Operation - Lutron Electronics DM-9961 Manual

Remark :
Under the ACV measurement ( 5-2 ) or ACA
measurement ( 5-4 ), if push the " Hz/DUTY
Button " ( 3-6, Fig. 1 ) once a while , will also
can measure frequency value or DUTY value of
the measured ACV or ACA.

5-9 Relative Measurement

1)During the measurement, the circuit will memorize the
last measured values if push the " REL. Button " ( 3-4,
Fig. 1 ) at once, then LCD will show zero value & a "
REL " indicator.
2)The input measured values will deduct last measured
values " automatically, then show those new value on
the display.
3)It will cancel the relative measurement function if
push the REL. button at once again, at same time the
" REL " marker will disappear.

5-10 Data Hold Operation

1) During the measurement, pushing the " Hold button "
( 3-2, Fig. 1 ) once a while will freeze the measured value
& the LCD will indicate " HOLD " symbol.
2)Push the " Hold Button " again to cancel the data hold
function.
