For field measurements, HI 98703 is powered by 4 AA batteries.
The battery life is enough for 1500 normal measurements.
When the instrument is started, the remaining battery life is
estimated and reported in percents.
To preserve the battery it is better to use normal instead of
averaged measurements.
Continuous measurements keep the lamp on and should be used
with caution if the battery life is an issue.
To further save the battery life, the instrument will turn off after
15 minutes of non-use. The backlight will be turn off after
25 seconds since the last key was pressed.
The battery life is measured each time the lamp is turned on and
if the remaining battery life is less than 10%, the battery tag will
be displayed blinking on the LCD to warn the user that the
batteries need to be replaced.
When the batteries are completely discharged, “0% bAtt” message
will be displayed for one second and the instrument will turn off.
In order to use the instrument again, replace the batteries with
new ones or use an AC adapter.
