The EDL175 Portable Event & Data Logger - Extended Range measures, records and analyzes events and data of electrical network parameters. Being mobile, it enhances efficiency by enabling onsite identification of power problems. The EDL175 meets the requirements of a wide range of applications, from events analysis to energy auditing and load profile recording over a period of time. The EDL175 parameters include all the measurement and logging capabilities of the PM175 Powermeter in a convenient, portable package. The manufacturer's PAS software package included in the EDL175 provides graphic data display and analysis capabilities. The EDL175 is suitable for direct measurement of voltages up to 660V (or greater when using a Potential Transformer). The EDL175 is equipped with standard clamps with secondary current of 1A. It is also possible to use FLEX sensors with secondary voltage of 2VAC or 3VAC or standard clamps with secondary voltage up to 2VAC or 3VAC. The EDL175 can measure low currents in the range of 100mA to 10A, in addition to the standard ranges, with a high degree of accuracy, using standard high current clamps. This additional measurement capability is made possible with the combination of standard current clamps and the manufacturer's special cables and electronic circuit. One application is using standard current clamps to measure the standard 5A output CTs. The EDL175 has an internal DC battery which enables it to continue working even when the power supply is disconnected for short intervals, as in a power failure.
