EXAMPLE 4:
To test the power supply and load on an IRS
installation
1. Disconnect the EV5-034 power supply from the DC auxiliary
input of the EV5 multiswitch.
2. Connect the power supply to the DC input (source) on the
meter.
3. Check the voltage reads 18V.
4. Connect the TV/SAT Power Meter DC out (load) to the Auxiliary
DC input of the multiswitch.
5. Press and hold the red "test" button.
6. Check the voltage remains at 18V when under load.
7. Add the current rating for each device on the system including
all multiswitches, the LNB and any amplifier.
8. Check the current displayed matches the total system load
9. If the voltage under load is below 18V check the power supply is
not faulty.
10. If the current displayed is significantly higher than the
calculated current, check for faulty connections (whiskers of
braid) and also for faulty equipment. Use a process of
illumination to check for faulty equipment.
