Discontinued products
• Can measure Flicker in accordance to IEC 61000-4-15 and EN50160 standards. Using our Flicker sensor, available as optional accessory, Pst value (short term severity in 10 minutes value) and the Plt value (long term severity in 2 hours value) can be measured.
• 12 kinds of Power Measurements for Power Control and Applicable to Power Quality Control including Harmonics Analysis.
• One click easy-to-use operation helps complicated setting and processing of large data through the setting / analyzing software provided as accessory.
• Direct communication with PC via USB cable
• Built-in Input / Output Function of external signal enables the signal transmission to alarms.
• 2-way power supply by AC and Battery, and Nickel hydrogen battery usable with rechargeable function.
• Pull / Insert of CF card possible whenever on recording under the function of memory backup device.
• Can monitor insulation at leakage current by using optional leak clamp sensors.
• Built-in Print Screen Function enables to record display screen
(Records 512 screens by using CF card: 1 screen 40KB).
• Can display Waveform and Vector, and can confirm the wiring connection, too.
• Complies fully with International Safety Standards IEC 61010-1 CAT III 600V.
  • TRUE RMS

* Attention for KEW6310 customers:
Flicker measurements are possible with firmware of KEW6310 upgrade (Ver.2.01), PC software PQA Master upgrade (Ver. 2.01) and an optional accessory Flicker sensor KEW8325F.
