2. Features
KEW 5020 is a Data Logger capable of measuring Leakage Current,
Load Current and Voltage. (KEW5010 is for measuring Leakage Current
and Load Current).
Following sensors are used for measuring current & voltage.
* Leak/Load Current Clamp Sensor KEW 8146/8147/8148
* Load Current Clamp Sensor KEW 8121/8122/8123
* Voltage Sensor KEW 8309 (for KEW5020)
TRMS measurement & recording of AC Current (50/60Hz) & AC Voltage
(50/60Hz, only on KEW5020)
LED to indicate pre-set current/ voltage value is exceeded.
(Trigger/ Capture Recording, Power Quality Analysis modes)
Can store 60,000 data when using 1ch, and when using all 3ch, can
store 20,000 data at each channel. (Normal recording mode)
Data will not be lost at battery replacement or at low battery voltage as it
is stored in nonvolatile memory.
Long time recording is available by a use of external AC Adaptor
(optional parts) Installed batteries enables backup at a temporally
electricity failure. Size AA Alkaline Battery: about 10-day measurement.
Can transfer the recorded data to PC via USB cable.
Protected throughout by double (reinforced) insulation “ ”
This instrument provides 3 Recording modes and Power Quality Analysis
mode (only KEW5020). Various insulation monitoring are available with 4
recording modes. Understand characteristic of each recording mode and
select an appropriate mode.
