Keterangan :

3 channel inputs for the simultaneous recording of Leakage Current, Load Current and Voltage
• Power Quality analysis
( only on KEW 5020)
( Power Quality: Reference voltage, Swell, Dip, Short power Interruptions)

Large Capacity for storing 60, 000 data points
60, 000 data points can be recorded when 1ch is used, and when all the three channels are used, 20, 000 data points per channel can be recorded

Lowpass Filter will filter out the harmonics
( Cutoff Frequency = Approx. 160Hz)

LED flickers when the preset current / voltage value is exceeded

CALL: Confirmation of recorded data
• The following can be displayed: number of recorded data points, ( max+ min+ peak) value for each channel complete with time/ date information in the Normal recording mode. ( Detected values ( i.e. when values are outside preset limits ) can be displayed in other recording modes)
• RECALL: The last 10 recorded data points including time/ date can be recalled on the logger display

Selection of One-time mode or Endless mode
• One-time on: Recording will stop when memory is used up
• One-time off: Overwrite the old data, and store the latest data

Non Volatile Memory
Recorded data will be retained even if the batteries are exhausted or replaced due to the presence of a nonvolatile memory ( guaranteed for 10 years)

Battery power indicator
Indicates battery voltage in 4-levels
( It is possible to use the logger for a further approx. 24 hours even after the warming symbol is flashing)

The userfriendly PC software " KEW LOG Soft 2" is supplied
• Supplied with the user friendly software " KEW LOG Soft 2" . This permits editing, analysis and graphical display of data.
• The recorded data is downloadable onto a PC via USB cable.
• Variation of the measured voltage and current data can be confirmed simultaneously on the PC display monitor. ( only on KEW 5020)
• Simplified Power Integration
( The " KEW LOG Soft 2" uses current and voltage recorded to calculate the integral power consumption)
• Continuous measuring time: Approx. 10 days ( Alkaline Battery)
