It is one of the most useful tools that you might have to configure your plate. This device is connected between the parabolic antenna. And its receptor and allows you to find the satellite, without having to use the meter on your TV. Features: brand new and high quality. With H/V and 22KHz indicators. Indicator lights for verifying that your receiver is set to Horizontal or Vertical polarity and if 22KHz tone is on or off. Green H/V light indicates Vertical Polarity. Red H/V light indicates Horizontal Polarity. Red 22KHz light indicates 22KHz is ON. When aligning a C-band dish do not use your meter in front of the dish to avoid full scale readings. When connecting to a LNBF with gain higher than 65dB, insert a 5dB attenuator between the meter and the LNBF. If a attenuator is not available you may use a long coax (60 feet or more) between the meter and the LNBF. If the meter needle is jumping the sensitivity is too high. Adjust the S.A. level on the back of the meter by punching through the label where marked. Be very careful not to damage the adjustment by turning it too far or too hard.
