|The last PentaScanner left the factory back on 31 de março de 2004. We regret to say support ended 31 de março de 2008. It's replaced by the Versiv familly of testers|
Perda de retorno
If (Over range) is displayed, the Return Loss is less than 20 dB.
If (Over range) is displayed, the Impedance is greater than 200 ohms, the cable is less than 40 feet long, or the cable/pair is not connected.
Count indicates the cumulative count of impulses detected since the start of the measurement. When the Count exceeds 65535, (Over Range) is displayed. In an Over Range condition, the last average CPS (Counts Per Second) recorded is displayed.
If the Peak-to-Peak noise level exceeds 3.000 mV, (Over Range) is displayed.
Resistência de Loop DC
If (Over Range) is displayed, the Loop Resistance is greater than 10K ohms.
If (Over Range) is displayed, the Capacitance is greater than can be measured or the cable is properly connected.
