Torque Meter Frequently Asked Questions

1. Front panel

(1) POWER Switch
This is the main power switch of the device. Pressing the upper side of the switch turns the power on.
(2) POWER LED
The green LED lights up when the main power is supplied.
(3) TRQ LED
The green LED lights up when measurement signals SIG1/SIG2 from the torque detector are both input.
(4) REV LED
The green LED lights up when signals from the rotation detector, such as MP-981, are input.
(5) TQR ZERO Switch
This is a digital switch for setting the zero value of torque.
(6) ANALOG ADJ TRQ ZERO / FULL
This potentiometer is used to adjust the calibration of the analog output for torque data.
(7) ANALOG ADJ REV ZERO / FULL
This potentiometer is used to adjust the calibration of the analog output for rotation data.
