Each ASG-DTT meter is designed to give convenient and accurate torque
measurement in a portable unit.
The unit can be used with most torque setting devices including Hand torque
screwdrivers, Electric torque screwdrivers, and pneumatic screwdrivers.
Do not use this unit with impact tools. The purpose of the unit is for setting the

CHARGING THE BATTTERY AND PREPARING THE UNIT FOR USE
Before using the DTT-100 make sure, the batteries have been charged for at least 4
hrs. If the batteries are low, the LCD may not function. A "Low battery" warning may
also be displayed on the LCD when the unit is turned on. The words "battery empty"
will be displayed briefly before the unit automatically shuts down.
If the battery is dead and you wish to use the meter, it is acceptable to occasionally
use the unit with the battery charger plugged in while the battery is charging. If the
battery dies during use, the on/off switch will need to be cycled to use the unit after
the charger is connected. Allow the battery to fully charge then detach the charger.
The battery will be fully charged after up to 4 hrs of charging.
CAUTION
If the battery overheats during charging a thermal fuse will open. The unit will not
operate until the fuse resets. Allow the DTT meter to sit for up to 30 minutes with the
charger disconnected then turn the unit back on.
Only use the charger supplied with the DTT meter. The supplied charger is a battery
charger only. It is not to be used as an AC adapter to power the DTT meter in place of
using the batteries in normal operation.
