Press the TEST button from the Idle Screen and select the desired test. |
The OpenMeter first measures Voltage, then Resistance, and finally Capacitance of each terminal. If voltage or resistance is found the reading is displayed in reverse video, otherwise the distance is displayed. The screen shot to the left shows voltage between T and R while showing the cable length of the Tip and Ring conductors. |
Ring Ground Fault. |
Leakage tests are made only on the selected terminal. Press F1, F2, or F3 to select the desired terminal. |
Metallic (TR) noise should be less than -70dbm. The higher the negative number the lower the circuit noise. Excessive ground noise, Longitudinal Noise, is usually an indicator of poor bonding or shielding. |
