Quick Manual DIGITAL POWER METER KEW 6305
Preface KEW6305 ● Preface This Quick manual is a simplified version of the full instruction manual which can be found in the supplied CD-ROM. This manual is intended only as a handy reference guide and should only be used after having read the full instruction manual which contains full details on each function of this instrument and the items contained in the package.
KEW6305 Instrument Overview 1. Instrument Overview Features This is a digital Power meter that can be used for various wiring systems and can measure up to 3 systems on single-phase 2-wire circuit. That is, this instrument does the jobs of three just by one. It can be used for measurements of instantaneous, integration and also demand values. Measured data can be saved in SD card or the internal memory, and the data can be transmitted to PC via USB.
Functional Overview KEW6305 Functional Overview SET UP Configures KEW6305 and makes settings for measurements. WIRING CHECK Performs a check for proper connection. See (Section 10) “Wiring check” for further details. [W] Instantaneous value measurement Measures average, max, min values of instantaneous values of current, voltage and electric power. See (Section 6) “Instantaneous value measurement” for further details.

Preparations KEW6305 3. Preparations Battery KEW6305 operates either an AC power supply or batteries. Capable of performing measurements in an event of AC power interruption, power to the instrument is automatically restored by the batteries installed in the instrument. Size AA alkaline dry-cell batteries (LR6) can be used. If an AC power supply is interrupted and batteries have not been installed, the instrument will be powered off and the measuring data may be lost.

Measurement Ranges KEW6305 5. Measurement Ranges KEW6305 can perform the following three different measurements. (a) Instantaneous value measurement (W Range) (b) Integration value measurement (Wh Range) (c) Demand measurement (DEMAND Range) Select a desirable Range according to the steps below. 1. Set the Function Switch to W/ Wh/ DEMAND Range. Set the switch to W/ Wh/ DEMAND position. 2. Select a Range Any one of following symbols blinks on the LCD to show which Range has been selected. e.g.
Instantaneous value Measurement: W Range KEW6305 6. Instantaneous value Measurement: W Range 6-1.
Selecting/switching display contents KEW6305 6-2. Selecting/switching display contents Three parameters (max) can be displayed in one screen. (In the example 1-A below, V, A and P are displayed.) Display screen will be different depending on wiring systems. ● e.g.
