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 by 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.
The contents of the EDL175 case are shown in Figures 1-1 through 1-4. Instrument dimensions are
shown in Figure 1-5.
Section 2 of this manual provides installation instructions, including wiring mode, CT and PT setup,
as well as connection of voltage probes and current sensors. Section 3 provides information on the
internal battery and an explanation of the EDL175 indicator lights.
