FT. LBS. Nm
Straight 147.5 200
"V" 196.2 266
"X" 312.7 424
In order to calculate the calibration value for the system in % full scale, the following formula may be used:
% FS = Rbr 1 1
------------------ X ----- X -----
2(Rcal) + Rbr Vo
2
Where Rcal = Calibration Resistor Value in ohms of the torque monitor used.
The following is an example of a 75 series right angle tool, a "V" head and a torque monitor with a 110,000ohm calibra-
tion resistor.
The values are: FS = 196.2 ft. lbs.
Rbr = 700ohm
Vo = .002
Rcal = 110,000ohm
700ohm 1 1
% FS = --------------------------- X ------ X ----- = 79.3%
2(110,000ohm) + 700ohm .002
2
Calibration Value = 196.2 (.793) = 155.6 ft. lbs.
*Calculated calibration value should be doubled if a torque monitor designed for use with a 350ohm bridge resistance
transducer is used.
