The calibrated offset of the 3410 may be changed using the tare function. To set:
1. Press TARE button.
2. Display will flash “TARE” and the unit will take the current value of the torque input and
make it the new zero.
Note:
In order to reset the tare value, the power to the unit must be turned
OFF.

Built-In Test Equipment (BITE) has been programmed into the 3410 in order to test the system and
make sure all devices are connected and running properly. When the BITE function is activated the
software will turn on an NPN transistor internal to the 3410 that is in an open collector configuration.
This output, or collector, is found on pin 12 of the 14-pin connector on the back of the unit. This
signal is routed to the transducer and will activate internal circuitry to output a test signal. In the
case of a TM series transducer, the output will be 5 volts (full scale) in addition to any offset value.
As for the TF series, the output will be about 4 volts (about 80% of full scale) in addition to any
offset value. To activate:
1. Press SELECT and TARE buttons simultaneously.
2. The display will flash “BITE”, then provide the full-scale voltage at the input of the unit.
