NOTE As new firmware versions are introduced Energoform 3 1 operator interface may be slightly modified with respect to the order of displaying information The changes never affect metrological and technical characteristics of the Generator Observe the following rules when you use keyboard to change values of active modifiable fields within current window 1 Keys increase or decrease respectively the value of an active field The longer the key remains depressed the faster the active field changes its value 2 Suppose the active field can be changed cyclically like phase shift expressed in angular degrees When its growing value reaches maximum with key still hold down minimum value appears in the field and start growing again When you depress and hold gt key the value goes the other way round having dropped to its minimum it becomes maximum and start decreasing again 37 P MARS ENERGO 3 When value in the active field is not of cyclic nature it can only be changed in both directions within its permissible interval 4 By pressing number keys O to 9 you can immediately type in the desired value within permissible interval established for the field currently active 5 Suppose you modify the value of an active field formatted to have integer and fractional parts By pressing decimal comma key you terminate integer part of the number and change number entry mode accordingly Then you specify the fract
