Parameterization The flow meters type IZMSA supplied by Negele Messtechnik GmbH have been preset at the factory to the parameters (pulse value, flow range, etc.) desired by the customer. Modifications of the parameter settings can be carried out straight by the integrated display unit or the service terminal ST6X.
Inadvertent modifications of the parameter data might result in malfunctions thus requiring cost-intensive servicing. For that reason, the IZMSA is equipped with different safety devices against unintended changes. In principle, the calibration switch “CAL/MEAS” on the lower board serves for that purpose. In the normal measuring operation, the switch should be set to “MEAS”.
