Shock sensor calibration

Hello, I'm trying to use the Sensor calibration option for my shock sensor but no matter which numbers I enter, (from 0.3 to 930.00), after clicking update, nothing changes on sensor measurements. Can you provide me with calibration directions?



I need to do it as I have one sensor that says it detects from 0.85 to 0.95 G, but a new shock sensor installed just 0.5 cm to the left of the 1st one, is detecting from 0.2 to 0.3 G. Can it be calibrated or it's a failing sensor?

Unfortunately as of the moment, offset values can't be set on the shock sensor
