Please tell me how to install the weight sensor.

TTS series, and LTS series are manufactured to the desired specifications, so tapping holes for fixing can be machined at any location.

There are two types of fixing methods for the STS series, and you can choose from them.
(1) Remove the cover fixing screws, and there are two fixing tap holes on the lower plate, so fix from below
(2) Since there is a large hole in the upper plate at the tap hole position, fix it via the hole in the upper plate
