2 in 1: Cable fault meter and line qualifier!
The KE3700 CT is the tool for fault analysis in the DC and AC range with cable multimeter function incl. resistance fault localisation, TDR function for cable fault location and measurements for line qualification up to 31 MHz.
The device allows the qualification of a copper wire pair to the service to be transmitted. Predefined or manually editable filters are available for xDSL or telephony services in the frequency range up to 31 MHz.
To simplify measurement tasks, manual and automatable test sequences are available to the user in combination with the electronic remote line switch KE905 Remote, which is included in the scope of delivery of the KE3700 CT.
Measurement results can be stored on a USB storage device, to electronic order processing systems via QR code or to the included KE Manager PC software for data evaluation and the creation of measurement protocols in PDF form.
The security glass protects the screen from impact and ensures good readability even in sunlight.
