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儀表是一種數(shù)字式可編程的面板儀表，用于測量交流電壓、交流電或頻率。讀出顯示是一個LED顯示屏，它能顯示出紅色、綠色或橙色的結(jié)果。

該設(shè)備滿足了為工業(yè)應(yīng)用設(shè)計(jì)的產(chǎn)品的III安裝的要求——看視頻展示，它有多重要。

·         input:
– a.c. current: 1 A, 5 A,
– a.c. voltage: 100 V, 250 V, 400 V
– frequency: 20…500 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.

特性

?輸入:

- A .c電流:1 A, 5 A，

- a.c電壓:100v, 250v, 400v。

-頻率:20…500 Hz。

?OC類型(4種報警器)的2個報警輸出信號通過報警指標(biāo)高亮顯示，

?住房保障水平:IP65，

?讀出場:5個3色LED顯示14毫米高，

?強(qiáng)調(diào)測量單位,

?供應(yīng):85…253 V交流/直流電。或20…40 V交流/直流電。

?整體尺寸:96×48x64毫米。

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.

對于N20Z的配置是命中注定的lpconfig程序。儀表必須通過PD14轉(zhuǎn)換器與PC機(jī)連接。

可重新編程的參數(shù)如下:

·         顯示顏色，每隔三次，

·         顯示溢出的閾值，

·         顯示結(jié)果的精度(小數(shù)點(diǎn))，

·         單元的亮點(diǎn)，

·         測量信號a.c或a.c. + dc(真有效值)，

·         平均測量時間，

·         重新敘述適應(yīng)癥(個人特征)，

·         在六種工作模式下使用OC類型的兩個告警。
