2.10 Battery Low Warning
2.11 Beep Tone
･
When this indication appears, the battery is depleted.
During which time accuracy cannot be guaranteed.
Replace the batteries as soon as possible.
･
To check remaining battery life, check the bar graph,
when powering on or by pressing OUTPUT . The
bar graph provides a rough approximation of
remaining battery life. Be careful for the battery life
especially before using an output function for a long
term or when using the REC function.
･
Batteries tend to increase in voltage somewhat when
left unused for a long period. Even if the battery
warning annunciator becomes temporarily off after
the period, replace the battery as soon as possible.
If the battery is not replaced at this point in time,
the annunciator may not light up immediately on the
next occasion. Replace a new battery before it ruins
a measurement or causes some other inconvenience.
(See Chapter 4: Battery replacement)
To disable the beep tone, hold RANGE when
turning the unit on by pressing
