Torque Meter Frequently Asked Questions

1. Front Panel

(1) POWER switch
This is the main power switch for this device. Press the top of the switch to turn on the power.
(2) POWER LED
The green LED lights up when the main power is supplied.
(3) TRQ LED
The green LED lights up when both measurement signals SIG1 and SIG2 from the torque sensor are input.
(4) REV LED
When a signal is received from a rotation detector such as the MP-981, the green LED lights up.
(5) TQR ZERO Switch
This is a digital switch for setting the zero torque value.
(6) ANALOG ADJ TRQ ZERO / FULL
When calibration the analog output of torque data, adjust it using this potentiometer.
(7) ANALOG ADJ REV ZERO / FULL
When calibration the analog output of rotational data, adjust it using this potentiometer.
