電參數(shù)波形數(shù)據(jù)捕獲： 捕獲快速變化的 RMS 數(shù)據(jù)，顯示半周期和波形來(lái)描述電氣系統(tǒng)動(dòng)態(tài)特性（發(fā)電機(jī)起動(dòng)、UPS 切換等等）。
能量損失分析器： 通過(guò)對(duì)標(biāo)準(zhǔn)的有功和無(wú)功功率測(cè)量、不平衡和諧波功率進(jìn)行量化，以確定電能損失造成的財(cái)務(wù)成本。
實(shí)時(shí)故障排除： 使用光標(biāo)和縮放工具分析趨勢(shì)。
安全級(jí)別： 引入線額定使用 600 V CAT IV/1000 V CAT III。
測(cè)量所有三相和中性線： 內(nèi)置 4 個(gè)柔性電流探頭，增強(qiáng)的細(xì)柔性設(shè)計(jì)以適合緊密的位置。
自動(dòng)趨勢(shì)分析： 每次測(cè)量都會(huì)自動(dòng)記錄，無(wú)需進(jìn)行任何設(shè)置。
系統(tǒng)監(jiān)測(cè)器： 根據(jù) EN50160 電能質(zhì)量標(biāo)準(zhǔn)，在一個(gè)屏幕上顯示 10 個(gè)電能質(zhì)量參數(shù)。
記錄儀功能： 可配置任何測(cè)試條件，可按用戶(hù)定義的間隔記錄最多 600 個(gè)參數(shù)。

電池壽命： 鋰離子電池組每次充電可運(yùn)行 7 小時(shí)。
The main features
400 Hz measurement: by increasing the power frequency to 400 Hz, transformers and motors are smaller and lighter than at 50 and 60 Hz, making them more useful for aircraft, submarines, spacecraft and other military equipment and hand-held tools. The model 437 II enables the measurement of power quality for such aviation and military systems.
Power inverter efficiency: the ac output power and dc input power of a power electronic system are measured simultaneously (using an optional dc current clamp).
Electrical parameter waveform data capture: capture rapidly changing RMS data, display half cycle and waveform to describe electrical system dynamic characteristics (generator starting, UPS switching, etc.).
Energy loss analyzer: the financial cost of power loss is determined by quantifying standard active and reactive power measurements, unbalanced and harmonic power.
Real-time troubleshooting: analyze trends using the cursor and zoom tools.
Safety level: rated 600 V CAT IV/1000 V CAT III for lead-in line.
Measure all three phases and neutral lines: four flexible current probes are built in, with an enhanced thin flexible design for tight positions.
Automatic trend analysis: each measurement is automatically recorded without any setting.
System monitor: according to EN50160 power quality standard, 10 power quality parameters are displayed on one screen.
Recorder function: any test conditions can be configured, and up to 600 parameters can be recorded at user-defined intervals.
View graphics and generate reports: comes with analysis software.
Battery life: the lithium-ion battery pack can run for 7 hours on each charge.
