Notes
i
A fresh pair of batteries has enough power either for about 1000
tests or for one year’s worth of tests. If you have changed the
brightness of the display to level 3 (high) or set Acoustic Mode to
on, the battery life will be shorter.
i
When you replace the batteries, your results always remain
saved.
i
The year, time and date settings only remain saved as long as
" you do not take longer than two minutes to change the bat-
teries,
" you do not press any button while the batteries are not
inserted,
" you do not open the drum compartment while there are no
batteries inserted.
" you turn the meter off before removing the batteries.
If one of the above conditions is not met you will need to re-enter
the year, time and date.
If you do not enter the year, time and date, all future results will
be displayed and saved without the time and date. In that case
