N20Z Digital Panel Meter

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. The LPCon program is destined for the configuration of the N20Z meter. 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.
The switching of the output alarm on is signaled by the highlight of the triangular alarm index, at the left side of the display for the suitable alarm digit
The highlight colour is always different from the colour of the displayed (measured) value. The protection level from the frontal side is IP 65. Meter overall dimensions: 96 ´ 48 ´ 64 mm (including terminals).
