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.
