Tension Display
During normal operation, the tension meter displays the
tension measurement. The current measurement displayed
is indicated by the Total / No. 1 / No. 2 indicator light.
Pressing the S button cycles between displaying the total
tension measurement and the tension measurement on the
No. 1 or the No. 2 sensor.

Alarm Display
When the tension measurement exceeds the threshold of
an alarm trigger, the display will alternate between tension
measurement and one of the following alarm messages:

"HI":

The alarm signal is output when the tension value exceeds
the limit set for maximum tension.

“LO”:

The alarm signal is output when the tension value is
below the limit set for minimum tension.

“Un.b”: The alarm signal is output when the tension difference

between the No. 1 and No. 2 tension values exceed
the set limit.
