full scale) and then zero the display. Press the zero keys even if the display shows
“000.0” This will compensate for small amounts of hysteresis (hysteresis is a natural
characteristic of steel).

Torque transducers are designed to give years of reliable operation if treated properly.
Torque transducers are sensitive electro-mechanical measurement devices and should
be handled with care.
Never over-torque a transducer beyond its usable range. It is good practice, when
possible, to select a transducer that is at least 25% greater in range than the expected
torque it will apply. This may help avoid accidental over-torque.
The torque transducers that are supplied with the torque meter will accept up to 50%
over torque without damage. However, if this should occur we recommend that you
return the unit for a calibration check.

The torque meter has an audible warning system that will alert you if you have
exceeded the usable range of the transducer. A constant beeping sound will occur.

non-torque noise or vibration that may be input
from a high speed power tool. Use a lower filter
setting if you are getting occasional spikes in the
reading.
