Calibration and Adjustment

Calibration and Adjustment

Background During calibration, a check weight is used to determine how much the displayed value deviates from the actual measurement value. This deviation is compared with an entered target value and this deviation is then eliminated by a subsequent adjustment of the balance. During linearization, the deviation of the values from the ideal characteristic curve is cleared.

Not all functions/settings can be selected on balances used in legal metrology!

When and how often Calibration/Adjustment should be carried out on a regular basis, e.g., daily after the balance is turned on. In addition, it should be done after each leveling and always when the ambient conditions have changed (temperature, humidity or air pressure), and when the balance has been set up in another location.

isoCal All Cubis balances are equipped with the automatic calibration function isoCal (time and temperature-controlled). You can adapt this function according to your requirements. You can set up a memory function that triggers a prompt for calibration/adjustment at specified intervals.

hThe process for the calibration/adjustment function may differ depending on the presets (see System Settings/Configuring Calibration/Adjustment). The factory settings have not been changed for the procedure described here.
