便攜式和手持式儀器

Yokogawa橫河的便攜式和手持式儀器包含各式各樣的便攜式測試設備，以滿足各種短時間或連續測量應用的要求。我們種類齊全的產品包括：校驗儀、DMM、鉗式測試儀、便攜式鉗式功率計、便攜式數據記錄儀、絕緣測試儀、溫度計、便攜式電流/電壓表、照度計、高精度測量設備，等等。

便攜式鉗式功率計

能效問題已受到全球范圍內的普遍重視，需要有合適的產品來監視每個工廠的能量要求。CW240和CW120功率監視器系列允許客戶使用便攜式記錄裝置來測量電壓、電流、功率、Var、VA、PF、PA、頻率、諧波和需量。1P2W到3P4W功率監視器提供當前電力狀況的可視化報告，以防止發生重大能耗問題或電費超支。

CW10與其說是記錄儀，不如說是一款測試儀，可以測量單相AC和DC功率、電壓、電流、功率因數、頻率、諧波。該產品是用電設備維護人員的得力助手，也適用于太陽能和風力發電等可再生能源的設備。

Quick Start Guide Function:

The Quick Start Guide Function supports correct wiring and setting before measuring.
The Quick Start Guide Function automatically recognizes the type of current clamp probe.

Vector Display:

The Vector Display indicates Voltage and Current phase difference and values between input channels of voltage and current.
The Vector Display checks whether the wiring is correct or not.

Power Quality Measuring

Measure Temporary Malfunctions of the Power Line

The CW500 captures temporary malfunction phenomena of the power line that can cause malfunction or destruction of devices due to voltage swell, voltage dip, interruption, transient voltage over, and inrush current by using a high sampling rate of 24 µs and RUS calculation.
Event data contains the type of malfunction, occurred time or occurrence finish time, measured value and waveform of voltage and current of all channels for approx. 200 ms period.
This measurement method conforms to IEC standard 61000- 4-30 Class S

Measure Continuous Malfunction of the Power Line

Harmonics

Measure and display graphs and lists of up to the 50th Harmonic components of voltage, current, and power for each phase and total.

Flicker
