1. APPLICATION and DESIGN of the METER
The N20Z PLUS meter is a digital programmable panel instrument designed for
measurements of a.c. voltages, a.c. currents, or frequency. The readout display is a
LED display which enables the presentation of measurements results in red, green or
orange color
The N20Z PLUS meter has a built-in RS-485 interface and the MODBUS RTU
protocol provided, by means of which it is possible to configure the meter or read the
measured values. The meter is compatible with free E-Con software available for
download on the manufacturer's website. The meter should be connected to a PC via
the RS-485 to USB converter, e.g. PD10. Parameters that can be reprogrammed are
as follows:
- display color, individually in three colour versions,
- thresholds of displayed exceedings,
- result display precision (decimal point);
- backlight;
- rtype of the measured signa, AC or AC+DC (True RMS);
- averaging time of the measurement;
- recounting of indications (individual characteristic);
- operation modes of two OC type outputs, 6 operating modes to choose;
- RS-485 transmission parameters
- MODBUS bus settings
The meter is equipped with two OC type outputs. The activation of the output
is signaled by the backlight of the triangular alarm indicator on the left side of the
display with the corresponding alarm digit. The backlight color is always different from
the color of the displayed measured value.
The degree of protection of the meter from the front side is IP65. Dimensions
96 x 48 x 64 mm (including terminals). The housing is made of self-extinguishing
plastic.
