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。
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.

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。
