Specification :

The N20 meter is a digital programmable panel instrument destined for measurements of d.c. voltages, d.c. currents or temperature. The readout display is a LED display which enables the exposition of results in red, green or orange colour.

Parameters of the N20 meter:

* input:
- d.c. current: 0/4...20mA; ±20mA
- d.c. voltage: 0...60mV; 0...10V; ±10V
- temperature: Pt100, J, K
* 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 N20 is destined LPCon 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.

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, 300 V, 500 V
- frequency: 20...50 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.
