TAWM SERIES
When length of an offset (or sum of head minus offset for interchangeable head) is negative, maximum
fastener target is limited by following formulas:
STD
135 Nm wrench:
Maximum Target Torque = offset *4,1 + 135
Offset (cm) Max Target (Nm)
-1 131
-2 127
-3 123
-4 119
800 Nm wrench:
Maximum Target Torque = offset *7,6 + 800
Offset (cm) Max Target (Nm)
-1 792
-2 785
-3 777
-4 770
SLIM
10 Nm wrench:
Maximum Target Torque = offset * 0.435 + 10
Offset (cm) Max Target (Nm)
-1 9.57
-2 9.13
-3 8.70
-4 8.26
Note: When using a negative offset, entering a target torque greater than maximum values
above may cause an overtorque error before reaching fastener target torque and possibly
damage wrench.
VIEWING STORED TORQUE AND ANGLE DATA
Torque data is stored in memory after each torque cycle if applied torque has reached target value.
Torque and angle data is stored in memory after each angle cycle if applied angle has reached target
value. Memory Indicator is displayed when data is stored in non-volatile memory.
1. To view stored torque and angle data, from target torque or angle screen, press and hold ENTER
button for 3 seconds.
2. Highlight SHOW DATA menu selection by pressing UP/DOWN buttons then press ENTER button to
display Show Data screen.
3. In Show Data screen, scroll through each stored data record by pressing UP/DOWN buttons.
340 Nm wrench:
Maximum Target Torque = offset *6,1 + 340
Offset (cm) Max Target (Nm)
-1 334
-2 328
-3 322
-4 316
30 Nm wrench:
Maximum Target Torque = offset * 1.3 + 30
Offset (cm) Max Target (Nm)
-1 28.70
-2 27.40
-3 26.10
-4 24.80
Example:
0002 = Show Data List Counter: TQ = Peak torque value
0001 = Show Data List Counter: TQ = Peak torque value: ANG = Peak angle value
4. Pressing ENTER button while on Show Data screen returns to main menu.
STD
SLIM
Note: A maximum of 1500 data records can be stored. Memory full icon will be displayed when
full and no more data is stored until memory is cleared (on STD wrenches only).
Note: A maximum of 1500 data records can be stored in memory. Memory full icon will be
displayed when full. When full, a new data record will become record number 1500 and all older
data is shifted down one record number. Record 0002 becomes 0001 and old 0001 is dropped.
DELETING STORED TORQUE AND ANGLE DATA
1. From target torque or angle screen, press and hold ENTER button for 3 seconds.
2. Highlight CLEAR DATA menu selection using UP/DOWN buttons then press ENTER button to
display CLEAR ALL DATA screen.
3. In CLEAR ALL DATA screen, highlight YES menu selection to delete all stored data, or NO menu
selection to exit without deleting data.
4. Press ENTER button after making selection.
