POWERING THE FIRST TIME
The TT is supplied with a set of Nickel Metal Hydride 4xAAA re-
chargeable batteries. For safety reasons during transportation the
batteries are shipped discharged. To obtain maximum battery life
we recommend that you charge them with the supplied charger/
adaptor for at least 14-16 hours when you first receive the instru-
ment.
Battery Indicator
If battery level shows empty, a “ battery empty” message will be
displayed and the tester will power down automatically.
Important: Only use the adaptor/charger supplied.
USING THE TT
Fitting Accessories
If power torque tools are used, the rundown adapter provided can
be inserted to the torque transducer head. For wrench and torque
screwdrivers, you may need a matching adapter.
Power Up
To power up the tester press the ON/OFF key. A short self-test
runs during which the display will show the capacity in Newtons.
The TT re-zeroes itself during the self-test routine.
After the self-test, providing no load has been applied to the in-
strument, the display will show all zeroes.
* Do not overload the load sensor. This will cause irreparable
damage. Torques greater than 120% of full-scale will produce an
audible beep and OL symbol will blink on the display until the load
is released and the RESET key is pressed.
To power down the tester press the ON/OFF key.
*All the current settings are saved when the tester is turned off. The
tester will function in the same mode when powered up again.
Basic Functions
Clock-Wise(CW) torque is displayed by the right pointing arrow
symbol (see image below). Counter Clock-Wise torque is dis-
played by the left pointing arrow symbol (see image below).
