1. Safety Warnings This instrument has been designed, manufactured and tested according to IEC 61010: Safety requirements for Electronic Measuring apparatus, and delivered in the best condition after passed the inspection. This instruction manual contains warnings and safety rules which must be observed by the user to ensure safe operation of the instrument and retain it in safe condition. Therefore, read through these operating instructions before using the instrument.
DANGER ¡ Never make measurement on the circuit in which voltage over AC300V exists. ¡ Do not attempt to make measurement in the presence of flammable gasses. Otherwise, the use of the instrument may cause sparking, which can lead to an explosion. ¡ Transformer jaw tips are designed not to short the circuit under test. If equipment under test has exposed conductive parts, however, extra precaution should be taken to minimize the possibility of shorting.

(1) Continuous recording mode ¡ Sampling period and RMS calculation The input signal obtained via the connected sensor is sampled (at 50Hz,approx 0.222mS; at 60Hz, approx. 0.185mS) just for 2-cycle (180 data). Then RMS value is calculated by the sampled 180 data. The instrument goes into stand-by mode till next recording interval comes. ¡ Recording The channels to which each sensor is being connected are switched in sequence at recording interval.
(2) Event recording mode ¡ Current detection and RMS calculation Sampling is performed consistently at 1.6ms intervals. Current is detected by comparing the 1/√2 times of the peak value of sine wave and the preset current value. At the same time, RMS is calculated at 100ms based on the sampling data at every 3.3ms.
(3) Max. value recording mode ¡ Current detection and RMS calculation Sampling is performed consistently at 1.6ms intervals. Current is detected by comparing the 1/√2 times of the peak value of sine wave and the preset current value. At the same time, RMS is calculated at 100ms based on the sampling data at every 3.3ms.
(4) Capture recording mode ¡ Current detection and RMS calculation Sampling is performed consistently only at Channel 1 at 1.6ms intervals. Current is detected by comparing the 1/√2 times of the peak value of sine wave and the preset current value. ¡ Recording When the preset current detection value is exceeded (Point A),the instrument records instantaneous values with corresponding time information for 200ms(10 to 12 waveforms) including 50ms prior to and subsequent to the cross over point.

8. Data transfer to PC ¡IInstall PC software "KEW LOG Soft" on your PC before using the instrument. Please refer to the instruction manual for "KEW LOG Soft" which shows how to install the software. (The instruction manual for "KEW LOG Soft" is contained in the supplied CD; or click "Start" → "Program" → "KEW" folder. ¡When connecting the logger to PC for the first time, your PC will recognize this new hardware and install the USB driver.
8-2 Preparation for data transmission (1) Power on the instrument, and get the instrument ready for a measurement. (Note: Data cannot be transferred while the instrument is performing a recording.) (2) Start up the PC software: KEW LOG Soft. 8-3 Operation of PC software Refer to the supplied instruction manual for "KEW LOG Soft" and transfer the data to your PC.
9. Battery replacement WARNING ¡In order to avoid electrical shock, remove sensors from the instrument when replacing batteries. CAUTION ¡Do not mix new and old batteries. ¡ Install batteries in the orientation as shown inside the battery compartment, observing correct polarity. When only the leftmost segment of the Battery mark is flashing on the LCD , it means battery voltage is low. Replace the batteries with new ones.
