Series TT02 Digital Torque Tool Testers User’s Guide 2 POWER The TT02 is powered either by an 8.4V NiMH rechargeable battery or by an AC adapter. Since these batteries are subject to self discharge, it may be necessary to recharge the unit after a prolonged period of storage. Plug the accompanying charger into the AC outlet and insert the charger plug into the receptacle on the tester (refer to the illustration below). The battery will fully charge in approximately 8 hours.
Series TT02 Digital Torque Tool Testers User’s Guide 3 SETUP Caution! Do not use Series TT02 torque testers with pneumatic or impact tools. 3.1 Using manual torque tools Use a bit adapter of appropriate size and place the tool into the receptacle, as shown in Fig. 1 below. Gradually exert torque by hand until the desired status is achieved (ex. click, slip, etc.). Fig. 1 Typical manual torque tool test 3.
Series TT02 Digital Torque Tool Testers User’s Guide 3.3 Proper alignment Align the tool axially with respect to the square drive in the receptacle. Side loading or off-center loading may produce erroneous readings, and can damage the instrument. Note: It is normal to detect a small amount of mechanical play in the receptacle. 3.

Series TT02 Digital Torque Tool Testers User’s Guide 5 OPERATING MODES Caution! In any operating mode, if the capacity of the instrument has been exceeded by more than 110%, the display will show “OVER” to indicate an overload. A continuous audible tone will be sounded (if beeps are enabled) until the MENU key has been pressed or the torque has been reduced to a safe level). Five operating modes are possible with the TT02 torque tester. To cycle between the modes, press MODE while in the home screen. 5.
Series TT02 Digital Torque Tool Testers User’s Guide 7 DIGITAL FILTERS Digital filters are provided to help smooth out the readings in situations where there is mechanical interference in the work area or test sample. These filters utilize the moving average technique in which consecutive readings are pushed through a buffer and the displayed reading is the average of the buffer contents. By varying the length of the buffer, a variable smoothing effect can be achieved.
Series TT02 Digital Torque Tool Testers User’s Guide SET POINTS Upper Disabled * Upper Enabled 5.00 Lower Disabled * Lower Enabled 3.50 Either one, two, or none of the set points may be enabled. To toggle between the clockwise and counterclockwise directions, press the DIRECTION key. If two set points have been enabled, they are displayed in the upper left corner of the display. If only one set point has been enabled, the word “OFF” will appear in place of the value.
