KEW6315 Feature

1.InstrumentOverviiiew

Feature

This is a Clamp-type Power Quality Analyzer that can be used for various wiring systems.

It can be used for simple measurements of instantaneous/ integration/ demand values, and also for analysis of harmonics and events related to power quality and for the simulation of power factor correction with capacitor banks. Moreover, it can display waveforms and vectors of voltage and current. Data can be saved either in the SD card or the internal memory, and can be transferred to PC via USB, or in real time via Bluetooth communication.

Safety construction

Designed to meet the international safety standard IEC 61010-1 CAT.IV 300V/ CAT.III 600V/ CAT.II 1000V. Power quality analysis

KEW6315 is designed to meet the international standard IEC61000-4-30 Class S and can measure frequency and r.m.s. voltage with high accuracy, and also can analyze harmonics. Moreover, it can measure swell, dip, interruption, transient, inrush current and flicker all at once without a gap.

Power measurement

KEW6315 measures active/reactive/apparent power, electrical energy, power factor, r.m.s. current, phase angle and neutral current simultaneously.

Wiring configuration

KEW6315 supports: Single-phase 2-wire (4ch), Single-phase 3-wire (2ch), Three-phase 3-wire (2ch) and Three-phase 4-wire.

Demand measurement

Electricity consumption can be easily monitored so as not to exceed the target maximum demand values. Waveform/ vector display

Voltage and current can be displayed by waveform or vector.

Saving data

KEW6315 is endowed with a logging function with the preset recording interval. Data can be saved by manual operation or by specifying date & time. Screen data can be saved by using the Print Screen function.

Dual power supply system

KEW6315 operates either with AC power supply or with batteries. Both dry-cell batteries (alkaline) and rechargeable batteries (Ni-MH) can be used. To charge the rechargeable battery, use the charger which is manufactured by the same company as the batteries. In the event of power interruption, while operating with

AC power supply, power to the instrument is automatically restored by the batteries in the instrument. Large display

TFT color display with large screen.

Light & compact design

Clamp sensor type, compact and light weight design.

Application

Data in the SD card or the internal memory can be saved in PC via USB. Analysis of the downloaded data and instrument settings are possible by using the special software “KEW Windows for KEW6315”. Real-time communication is available via Bluetooth.

Input/ Output function

Analog signals from thermometers or light sensors can be measured simultaneously with electrical power data via 2 analog inputs (DC voltage); when any events related to power quality occur, signals can be transmitted to alarm devices via one digital output.

Self-diagnosis

Self-diagnosis

If “NG” judgment is given frequently, there might be something wrong with the instrument. Stop using the instrument and refer to “Troubleshooting” in the instruction manual.

Sensor detection

If the detection result is NG, each sensor type will be displayed in red.

Criteria of judgment and cause

		Causes			Causes
		Check
		Type of			- Types of the connected current sensors are harmonized? Types of the current
		current sensor			sensors used for measurrements should be the same.
	???				- Current sensors are firmlly connected to the instrument?
		(cause unknown)			- If any failures are in doubt:
					Exchange the connecttions of the sensors and test again.
					Connect the current sensor, for which "NG" is given, to the CH on which
					another sensor is propperly detected.
					If the result "NG" is givven for the same CH, a defect of the instrument is
					suspected. A defect of sensor is suspected if "NG" is given for the same
					sensor connected to another CH.
					Stop using the instrument and the sensor, if any defects are in doubt, and refer

KEW6315								Operating procedure
Switching of displayed parameters
Basically, the	Cursor		Key		is used for selectting an item, the	ENTER	Key	is for confirming the
selection, and the		ESC		Key	is for canceling the alternation. Taking the procedures in “Quick Start

Guide” as an example, Key operations are explaineed as follows.

Press the Cursor Key to move the blue highlight, showing the item is being selected, over the items in blue letters. In the screen at the left is the Recording start screen. Press the Cursor Key and move the blue highlight on the desirable recording method, and press the ENTER Keyy to confirm the selection. To quit the start guide, press the ESC Keey.

If the display of the selectable items is similar to the one shown to the left, thhen the up, down, right and left Cursor Keys can be used. Use thhe Cursor Keys to select the proper wiring system and press the ENNTER Key to confirm the selection. To return to the previous screen and cancel the changes, press the ESC Key.

To alter the numbers such as Date/ Time, move the blue highlight over digits with the right and left Cursor Keys and alter the number with the up and down Cursor Keys.

In the screen to the left, the tenth place of the day is being selected. The number can be increased or decreased by 1 with the up/ down Cursor Keys. Press the ENTER Key to confirm the selection, or press the ESSC Key to return to the previous screen and cancel

the changes.
