15. BATTERY MANAGEMENT
For field measurements, HI83749 is powered by four AA batteries. The battery life is enough for 1500
normal measurements.
When you turn the instrument on, the remaining battery life is estimated and reported in percents.
To save the battery life, the instrument will turn off after 15 minutes of non use. The backlight will be
turned 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 blink on the LCD to advise the user to replace the batteries.
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 or use an AC adapter.
