OPERATION
1) Powering by Satellite Receiver or Internal Battery
The two power switches select between powering the meter from the satellite
receiver and simultaneously monitoring its LNB voltage and tone presence; or,
powering the meter and LNB from the internal nicad battery with the ability to
generate a 22KHz tone when required.
Note: Leave both switches in the "BATTERY OFF" position so as not to drain
the battery when:
a. The meter is not in use.
b. The battery is being charged.
2) Battery Check
Verify the condition of the battery by pressing: "BATTERY POWERED" plus
"18V" plus "V" on one meter. If the indication is "recharge" or in the yellow
position, it will be necessary to recharge the unit before use with the internal
battery is possible. A further battery test should be made under load (with the
LNB connected). It is recommended that the unit is charged overnight after
approximately three (3) hours use. Always charge with the 24VDC source as
supplied.
3) Wiring Diagram
A short cable should be used between the LNB and meter. Ensure the wiring is
completed before the satellite meter or receiver are switched on. Be careful to
avoid short circuits when the coaxial cables are connected or disconnected.

CAUTION: To prevent reverse powering the satellite receiver, never
connect the satellite receiver to the meter's LNB connector or
damage to the satellite receiver may result.
b. LNB powered from built-in battery.

4) 13/18V Selection
This button only functions in the battery powered mode. Press the13/18V switch
to select the desired LNB voltage.
Note: Avoid using the 13V position for extended periods. The 18V position
provides cooler operation.

5) 0/22KHz Selection
This button only functions in the battery powered mode. The 22KHz mode must
only be used with certain kinds of integrated LNB/multiswitch to select the
"alternate satellite" where direct access to the LNB is not possible.
Note: The instantaneous voltage at the "trough" of the 22KHz waveform will
be 0.3V lower than the indicated voltage.
The presence of a 22KHz tone from either the satellite receiver or internal
generator is indicated by the 22KHz LED.
6) LNB Voltage Measurement
Press the "V" switch. It indicates the DC voltage supplied to the LNB.
Note: The 13V and 18V LEDs provide a further indication of LNB voltage. The
LNB voltage is greater than 15V when the 18V LED glows and less than 15V
when the 13V LED glows.
7) LNB Current Measurement
Press the "mA" switch. It indicates the DC current supplied to the LNB.
8) Antenna Peaking
Coarse align the antenna using instructions supplied with your system. After
switching on, press the "level" (and tone switch if required). Adjust the dish
azimuth and elevation for maximum meter indication or highest pitch tone. Use
the gain control to maintain 80-100% of full scale deflection where meter resolu-
tion is optimum.
CAUTION: Note the LNB volts, LNB current and signal level switches
are interlocked. Never attempt to press more than one of these switch-
es in at the same time or damage to the meter may result.

1) Use 1008IFD battery power (not Sat Rx power) as the Sat Rx may not be able
to power 2 LNBs simultaneously. The tone feature is best switched off in this
application.
2) For each LNB, connect an LNB output to an LNB connector on the 1006IFD using
a short (less than 30 feet) coax cable.
3) For each LNB, select 13V, 18V, 13V/22 KHz, 18V/22 KHz as required.
4) Check the current to each LNB in turn (typically 170mA for a twin LNB).
5) Coarse align the antenna using instructions supplied with your system.
6) Adjust the dish azimuth and elevation for maximum meter indication on both meters
simultaneously. Use the gain controls to maintain 80-100% of full scale deflection.
In some installations, a slight compromise may be required between
optimum position for both satellites.
