  • Page 5: Application

    1. APPLICATION The N14 meter is a programmable digital panel instrument destined for the measurement of 3-phase, 3 or 4-wire power network parameters, in balanced or unbalanced systems with the simultaneous display of me- asured quantities and digital transmission of their values.

  • Page 6: Basic Requirements, Operational Safety

    3. BASIC REQUIREMENTS AND OPERATIONAL SAFETY In the security scope, the meter meets the requirements of EN 61010-1 standard. Remarks concerning the operator safety: All operations concerning the meter installation and connections should be carried out by qualified skilled personnel and national regulations for the prevention of accidents must be observed.

    Fig. 1. Overall meter dimensions 5. METER DESCRIPTION 5.1. Current inputs All current inputs are galvanically isolated (internal current transformers). The meter is adapted to co-operate with external measuring current transformers. Displayed current values and derived quantities are automatically re-counted by the quantity of the introduced external transformer ratio. Current inputs are defined in the order as 1 A or 5 A.

  • Page 14 6.4. Parametr preview Quantities are displayed in the measurement mode acc. to the set- tled tables. The pressure of the push (left) or push (top) causes the transition between displayed quantities. The preview of 3-phase values: mean, minimal and maximal is acces- sible after pressing the acceptation (Enter) push.

    6.5. Setting of parameters The entry in the programming mode is carried out by pressing and hol- ding during ca 3 sec. pushes. The entry in the programming mode is protected by the access code. In case when there is no code, the program transits into the programming option.
  • Page 16 Following values are set by means of pushes: Posi- tion of the decimal digit is selected by the push, the digit value is increased by the push. The active position is signalled by the cursor. The value is accepted by the push or abandoned by pres- sing the push.
