REPLACING BATTERY
For models ALH, ALHV, and ALHV-G if the battery is low, the LED will be illuminating on the front of
the instrument.
For model ALGR, if the battery is low, the LCD will display “ERROR BATTERY LOW”.
If the instrument operates erratically, try replacing the batteries. (Fig.15)
1. Remove the battery tray by unscrewing the plastic nut around the mounting thread
on the bottom of the instrument.
2. Remove the old batteries and replace with 4 new “D” cell Alkaline batteries.
3. Replace the battery tray. Make sure the battery contacts between the battery pack
and the instrument compartment are aligned.
NOTE:
Extreme temperatures and the use of batteries with different levels of charge can reduce
the operating time of the instrument. Always use batteries with the same power rating and
from the same manufacturer. For the proper disposal of the used batteries, see the section
“Environmental Protection”.

Rechargeable Battery Pack
If you are using a rechargeable battery pack (Cat #57-NMB700), your instrument will provide
approximately 14 hours of intermittent use with each full charge. The batteries will begin to
perform optimally after five full charges and discharges. You may charge the battery pack within
the instrument.
Ensure the power is off, and connect the charging plug to the appropriate charging jack on the
bottom of the battery pack. Then plug the charger into the appropriate 120/230V AC outlet. Charge
time is typically around 8 hours . The instrument can be charged and used at the same time, but
only a minimal charge will be applied to the battery pack.
