Data No.10 Calibration torque
The calibration value is set according to the tool type (capacity). However, depending on the applica-
tion characteristics or the prevailing torque generated external to the tool output shaft, the value of the
applied torque and the torque display by the Fusion unit may mismatch. In this case, it is possible to
adjust the FULL SCALE TORQUE (CAL) value, so the displayed torque matches the installation tor-
que registered by an external torque transducer (Master).
The CAL value can be adjusted up to
± 20 % of the FULL SCALE TORQUE value.
Example:
Consider the HFT-080M80-A tool . Nominal CAL value = 8.0 Kg.m.
Range of adjustment: from 6.2 Kg.m to 9.4 Kg.m.
Use the following formula on a collection of at least 10 fastenings when a calibration correc-
tion is necessary:
New CAL value = Master transducer mean/ FEC transducer mean x Existing CAL value
Note: The torque unit (Kgm, Nm, Ft.Lbs, etc.) must be the same for all terms. Do not
mix torque units in calculation or errors will result.
If the new CAL value is out of the adjustable range, the [Err] message will be displayed.
Example.
Tool Full Scale value (EXISTING CAL) is 78.4 Nm.
STD torque is 49.0 Nm.
Master transducer mean for 10 piece run is measuring only 47.5 Nm.
FEC transducer mean for 10 piece run is measuring 49.0 Nm.
The new CAL value is obtained as follows:
(47.5/49.0 x 78.4) = 76.0
The FULL SCALE TORQUE (CAL) value must be corrected to 76.0 Nm and en-
tered at [PARM} 1~16 [D-NO] 10.
Data No.11 Peak Torque Low Limit [Nm, Kgm...]
Data No.12 Peak Torque High Limit Nm, Kgm...]
Setting range: 0 ~ [10: Calibration torque] × 1.1
Setting points for the High and Low limits of the Peak Fastening Torque. If the High or Low limits are
exceeded the operation is rejected.
Data No.13 Standard Torque [Nm, Kgm...]
Setting range: 0 ~ [10: Calibration torque] × 1.0
Set point of the Fastening Standard (Target) Torque. This function is only available when Torque me-
thod is selected for [00: Fastening Mode].
