Detail
| • |
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. |
 |
| * 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. |
