Tare function
6.1 What is Tare function?
This function is a second load indicator with a temporary zero. When making a Tare, measuring Load calculations will not be aff ected. Press key (cid:1) T to set a Tare in the display when the display is showing the Load measured. Tare LED switched ON indicates, that the Tare function is active, and at that stage, the display may show “00000”. To exit tare function, keep pressing (cid:1) T .
6.2 What is Tare for?
This function is meant to control directly the loading and unloading regardless of the actual load of the tank. In case of a loading being done when the tank is not completely discharged. The function tare avoids the need of taking values to calculate the weight of an added loading. ● Example: Let say we have a 6000kg capacity silo storing a load of 1000kg. We plan to load the silo with 3000kg, therefore we should activate the tare function to set the display to Zero “00000” and then, the MLS displayed load will increases as the Tank is been fi lled. Once the load is fi nished the display will show 3000kg. This is a temporary function so when deactivating the tare function, the load indicator will show 4000kg.
Device Update
7.1 Firmware update
