N20Z

AC parameter digital panel meter for measurements of a.c. voltages, a.c. currents, or frequency.

  • AC voltage, AC current or frequency input
  • Wide voltage, AC/DC control
  • 3 Colour, 5 digit display. Red, green and orange

Product description

APPLICATION
The N20Z meter is a digital programmable panel instrument destined for measurements of a.c. voltages or a.c. currents, or frequency.

FEATURES
– three-colour display: red, orange, green, facilitating the observation of measured value changes,
– readout field: 5-digit LED, 14 mm digit height,
– 2 alarm outputs of OC type (4 types of alarms),
– signaling of alarm states through the highlight of the alarm index,
– housing protection level: IP 65,
– programming possibility of chosen meter parameters with the use of the PD14 programmer and free delivered LPConfig software:
- display colour, individually in three intervals,
- thresholds of displayed overflows
- display precision of the result (decimal point),
- highlight of the unit,
- kind of measured signal a.c. or a.c. + d.c. (True RMS),
- averaging time of the measurement,
- recalculation of indications (individual characteristic),
- two alarms of OC type operating in six working modes.
