PRE-LOCATION SCOPES : PCA100
The Adret PCA100 was developed to assist power and communication cable fault location technicians in pre-locating and pre-determining distances to faults existing in power cables. It gives a direct reading in meters to the fault distance. It is capable of locating low resistance (that is any fault lower than about 120 ohms or infinity ohms).
PRINCIPLES OF OPERATION
Operating Modes : TDR
In the TDR (Time domain Reflectometer) mode the instrument transmits a pulse which is reflected off the far end of the cable. Any impedance mismatches (i.e. Joints, open or short circuits) along the cable are also reflected. The waveforms are easy to analyze.
Features :
Locates faults quickly and easily
Automatically places cursors
Automatically selects range
Built in Backlight
Rechargeable Batteries
Simple keyboard
TESTS ARE POSSIBLE TO MOST WELL USED ISO SPECIFICATIONS
