cable pin configure). Also be sure that the Baud rate is identical on both

pieces of equipment.

NOTE: The headend unit’s channel plan does not have to

be downloaded to the Stealth field unit to achieve sweep.

Only the telemetry has to be the same. The channel plan

affects the other measurement modes.

NOTE: If a channel plan is made on the SDA field meter

and copied to the Tx, the Tx will freeze up and must be

shut off to reset. Only copy channel plans from field unit to

field unit or Tx to field unit.

On the receiver, select (Configure; Channel Plan; Copy Remote Plan) and

enter the forward plan for the system you are working on. The Tx then

downloads the plan you have built, but "sweep points" don’t show up in the

hand-held channel plan.

On the receiver, select (Configure; Sweep Receiver) and set the forward

sweep telemetry frequency to be the same as the Tx. Set for "Stealth" sweep

mode instead of "Sweepless".

Field Unit Settings

Select (Configure; Measurement) and insert all the required information

(Temperature Units, Signal Level Units, Fundamental Hum Frequency, Scan

Rate, etc.).

NOTE: Select “func” and “7” to enter the Test Point

compensation. There is a toggle button to select forward or

reverse Test Point compensation.

Before You Leave the Headend

Be sure the Tx is in the sweep mode.

When at the headend, ensure that your forward tilt channels are working

correctly by pressing the “Tilt” key. Then check the sweep. The sweep

direction can be changed on the receiver by using the left and right diamond

keys or selecting the following sequence: (Configure; Sweep Receiver;

Sweep Direction).
