PRODUCT DESCRIPTION

AC Parameter Digital Panel Meter, N20Z

The N20Z meter is a digital programmable panel instrument destined for measurements of a.c. voltages, a.c. currents, or frequency. The readout display is a LED display which enables the exposition of results in red, green or orange colour.

Parameters of the N20Z meter:

  • input:
    – a.c. current: 1 A, 5 A,
    – a.c. voltage: 100 V, 250 V, 400 V
    – frequency: 20…500 Hz.
  • 2 alarm outputs of OC type (4 types of alarms) signaled by highlight of the alarm index,
  • protection level ensured by the housing: IP65,
  • readout field: 5 three-colour LED displays of 14 mm height,
  • highlighted measuring units,
  • supply: 85…253 V a.c./d.c. or 20…40 V a.c./d.c.
  • overall dimensions: 96 x 48 x 64 mm.

For the configuration of the N20Z is destined LPConfig program. The meter must be connected with the PC computer through a PD14 converter.
Parameters which can be reprogrammed are as follows:

  • display colour, individually in three intervals,
  • thresholds of displayed overflows,
  • display precision of the result (decimal point),
  • highlight of the unit,
  • kind of the measured signal a.c. or a.c. + d.c. (True RMS),
  • averaging time of the measurement,
  • recounting of indications (individual characteristic),
  • two alarms of OC type operating in six working modes.
