RLX (OR RXLIOR) TO REPEATER VOLTAGE AND CURRENT TEST
Summary: This procedure provides instructions for measuring DC voltage and DC current being
supplied by the RLX or RLXIOR module to the T1 span repeater. The V+, V–, I+, and I– jacks
provide monitor access to the voltage and current supplied to the repeater through the DS1 span.
Measurements are taken at the test jacks on the RLX module front panel across a 10 ohm
resistor.
Measure DC Voltage
1. Refer to Figure 567-1 for an RLX front panel drawing. Select –VDC on the VOM and, if so
equipped, select a voltage scale of 0 to 200 volts.
2. Insert the black test probe into the V– test jack, and insert the red test probe into the V+ test
jack. Record the DC voltage for future reference.
Measure DC Current
3. Select –VDC on the VOM and, if so equipped, select the millivolt scale. The voltage in mV
measured between the I+ and I– jack is equal to the current in mA.
4. Insert the black test probe into the I– test jack, and insert the red test probe into the I+ test
jack. The meter should read approximately –600 mV (60 mA).
Stop! You have completed this procedure.
