The Kyoritsu 5020 is a compact three channel data logger, which can be used to simultaneously record leakage current, load current and voltage. With 4 recording modes, the Kyoritsu 5020 can undertake various measurements, and store up to 60,000 data points in it's non-volatile memory, meaning that even if power is lost, the recorded data is retained in the device. Setting up and configuration of the Kyoritsu 5020 is simple and can be performed in a few easy steps. The user has to simply connect the sensor, or sensors to the instrument, and confirm the recording mode to be used. These recording modes (Normal, Trigger, Capture and Power Quality Analysis) allow for various measurements to be made, depending on what parameters the user wishes to record. The data logger can also be fixed inside a metal distribution board with the magnet in it's rear side for ease of positioning and safety, and it's battery can allow for up to 10 days of recording (alkaline battery). An optional power supply is available separately, in the event that a longer recording is required. The LCD display makes most pertinent information available at a quick glance, such as mode, sensor connection status, max, min and average value for each channel, complete with time and date information (in normal mode). Detected values (for example when a parameter is outside of preset limits) can be displayed in other modes. Additionally, the last 10 recorded data points, including time/date can be recalled on the display. A LED on the front of the Kyoritsu 5020 flickers whenever the preset voltage/current value is exceeded. The Kyoritsu 5020 is also supplied with KEW LOG Soft 2, which is a Windows based software program used for analysing and processing of the recorded data with a PC. KEW LOG Soft 2 is an enhanced software program, which allows the user to configure data logger settings, process large data files, graph results, and display power quality issues, such as voltage swells, dips and interruptions.
