CALIBRATION

6.2RECHECKING ZERO

It is recommended that the zero is checked regularly. The frequency of re-calibration is dependent on the process. However, it is suggested that this be done at least every 6 months.

6.3AUTO CAL - ZERO SETTING PROCEDURE

AUTOCAL is a simple step by step calibration routine in which the user is guided through the calibration process by a series of user friendly screens. AUTOCAL is the recomended calibration proceedures.

The attenuation of the ultrasonic signal in dean liquid varies slightly from sensor to sensor. For optimum system accuracy it is important to set up this zero loss accurately. When the system has been installed, immerse the sensors in the clearest liquid available. If this is not practical, choose a point in the cycle when the liquid in the gap between sensors has the lowest possible % suspended solids. For example on sewage treatment plants wash water would be acceptable.

Firstly enable access using the “TOGGLE RUN” command in the MAIN MENU.
