- 3 channel inputs for the simultaneous recording of Leakage Current, Load Current and Voltage
- 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 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.
- Continuous measuring time: Approx. 10 days (Alkaline Battery)
