Taking the system into operation
To activate the weighing system, turn it on using the on/off button on the
terminal.
After 3 to 5 minutes the electronics and load cells have reached the
operational temperature. Before this, inaccuracies of up to ca. 0.3% may
occur.
Please note:
- It is recommended not to weigh loads before the zero-point correction has been executed.
- Temperature range: between -10 and +40°C the maximum inaccuracy is 0.1% of the weighed load. Outside this range inaccuracies up to 0.3% may occur.
- Fast temperature changes must be avoided because it can cause condensation in the electronics. During acclimatisation the weighing system must be switched off.
Maintenance
From time to time, every weighing system has to be calibrated. Yearly
maintenance of the weighing system is recommended. We strongly recommend that
approved weighing systems should be calibrated yearly, by a certified
institution.
Maintenance guidelines for a standard weighing beam or platform scale also
apply to the mechanical parts of the mobile weighing system. From experience
we know that the integrated weighing system still functions when the
mechanical parts are damaged by overloading.
Main guidelines:
- The electronics may only be cleaned with a moist cloth. Chemical cleansers and high pressure cleansing will cause damage
- Gathering dirt between the parts of the system can negatively influence the accuracy. Therefore, the system should be checked and cleaned regularly. Do not use high pressure cleansing.
- Only specialists may undertake any welding. This is to avoid damage to electronics and load cells.
Use

RAVAS WeightsApp
With the RAVAS WeightsApp you can read the data from your mobile weighing
system directly from your smartphone or tablet.
The app not only displays the weight in large digits on a smartphone or
tablet, it also stores the weighed gross weights, tare weight, product code,
date & time and the ID of the device or operator. The data can be sent to any
email address as a CSV file, after which it can be imported in a spreadsheet
program on a PC.
From the app you can:
- enter the ID of an operator or device
- enter tares (automatically or manually)
- zero the weighing system
Date and time are automatically generated. If your Android device has an
integrated barcode scanner, you can use it to enter product IDs.
In addition the app makes it possible to download a log file from the RAVAS
indicator and send it for technical analysis as a CSV file in the event of
malfunctioning.
The RAVAS WeightsApp can be downloaded for free from Google Play and the Apple
Store.
