Technical Data - Siemens 7MF4997-1BS Instrucciones De Operación

If the display capacity of the digital display DVM-LCD is exceeded, the display will show 9.9.9.9.9.. Applicable for all
modes: A new set value will be stored until the mode is changed or until the Module returns autonomously to the function
"Measuring value" approx. 2 minutes after the last key is pressed. In case of error the word Error and arrow up
