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 device fulfills the requirements of III installation’s category for the products designed to industrial application – see the video presenting, how important it is.

N20Z仪表是一种数字式可编程的面板仪表，用于测量交流电压、交流电或频率。读出显示是一个LED显示屏，它能显示出红色、绿色或橙色的结果。

该设备满足了为工业应用设计的产品的III安装的要求——看视频展示，它有多重要。

·         input:
– a.c. current: 1 A, 5 A,
– a.c. voltage: 100 V, 250 V, 400 V

·         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.

特性

•输入:

- A .c电流:1 A, 5 A，

For the configuration of the N20Z is destined LPConfigprogram. 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.

对于N20Z的配置是命中注定的lpconfig程序。仪表必须通过PD14转换器与PC机连接。

可重新编程的参数如下:

·         显示颜色，每隔三次，

·         显示溢出的阈值，

·         显示结果的精度(小数点)，

·         单元的亮点，

·         测量信号a.c或a.c. + dc(真有效值)，

·         平均测量时间，

·         重新叙述适应症(个人特征)，

·         在六种工作模式下使用OC类型的两个告警。
