5.5.1 Tension Tare
The tare function is a way to zero a small displayed tension value. Care should be
taken when using the tare function as the displayed value does not reflect actual line
tension but rather line tension minus the tare value. Any alarms that are set to
monitor the tension input will be triggered by the actual line tension value, not the
displayed value. The tare function can be deactivated at any time, returning the unit
to its normal tension display.
