7. Measuring Method 

 

    7.1 Notes in Measurement  

    ■ TD‑35 is a strain measuring instrument primarily for the static strain (DC

〜about 3Hz).

 

The A/D sampling frequency of TD‑35 is 6Hz. For the strain measurement of a 

higher frequency component, use the dynamic strain measuring instrument 

instead. 

 

    ■ Because the signal from the strain gauge or sensor is minute, pay special 

attention to noise intrusion.

 

For the signal cable from the sensor, use the dedicated 4‑wire shielded cable.

 

    ■  Use it where the signal cable does not touch or run parallel to the power line.   

Also keep the signal cable away from any strong magnetic field generating 

devices such as a motor or a power transformer. 

 

    ■ During operation, avoid direct sunlight, high temperature, high humidity, or 

places where dew condensation may occur such as rapid temperature or humidity 

changes. 

 

7.2 Wire Connection 

This is a strain indicator for measuring the strain gauge type sensor gauge output 

such as a load‑cell. For the strain measurement of an individual strain gauge, 

use the BX‑100 strain gauge bridge box with the 1‑gauge or the 2‑gauge method.

 

 

    7.3 Measurement   

 

     7.3.1 Strain Measurement 

Connect a sensor to ⑥  INPUT in the rear panel, switch ④  INDICATION to STRAIN, 

and ⑤  ZERO SET to OFF, then turn on the power. It is now ready in strain display 

mode.

 

 

   ■ Zero 

Adjustment

 

Switch ⑤  ZERO SET in the rear panel to ON, press ⑨  (↓Key) ZERO RESET while 

holding ⑬  SELECT button in the operation panel, and the display changes to 

zero and it is now ready for zero adjustment. The range of zero adjustment 

is ±10000×10

−6 

strain.  

When it exceeds the range, the LCD displays [OFF OVER] and you will not be 

able to return to the previous display for the zero adjustment.

 

When you wish to make a zero adjustment, set it to within ±10000×10

−6
