BATTERIES MANAGEMENT
For field measurements, HI 93414 is powered by 4 x 1.5V
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
blinking battery tag will be displayed 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 on the LCD 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.
