UMG 96-PA www.janitza.de4613. 3 Frequency measurementTo perform this measurement, the devicerequires the network frequency, which can beeither supplied by the user or automaticallydetermined by the device (cf. Section "Con-figuration").• The device can only determine the networkfrequency if there is a voltage L1-N great-er than 20 Veff (4-wire measurement) or avoltage L1-L2 greater than 34 Veff (3-wiremeasurement) at the voltage measurementinput V1.• The network frequency needs to be withinthe range of 45 Hz to 65 Hz.• If the measurement voltage is not suffi-ciently high, the network frequency can-not be determined, and subsequently nomeasurement can be performed.More information can be found in Section 12Configuration / Rated frequency"13. 4 Rotary field directionCheck the direction of the voltage rotary fieldon the measurement value display of thedevice.• A "right" rotary field is usually available.UL1-UL2-UL3 = right rotary fieldUL1-UL3-UL2 = left rotary fieldFig. Presentation of the phase sequenceaccording to the rotary field direction.To do this, open the menu display "Phasordiagram":• If you are not in the measurement valuedisplay "Overview," switch to this view byrepeatedly pressing key 1 (Esc).• Open the main menu with key 1 (Esc).• With keys 3 () and 4 (), select "Pointerdiagram" and confirm your selection withkey 6 (Enter).Fig. Main menu,Selection "Phasor diagram"
