Offset Level Settings
The image displayed to the right shows the offset levels for both the
high and low frequencies. These values are used to normalize the
leakage readings to typical system levels.
Example:
If the transmitter is injecting 60 dBmV at the ground block
and typical system level is 0 dBmV, with a 60 dB offset, the leakage
readings will reflect what the leakage values would be as if the launch
level at the house were 0 dBmV.
If the “Enable Meter Entry” checkbox is checked within the Seeker
Setup software during configuration, these levels are adjustable on the leakage detector.
We recommend to uncheck this setting so that these values are not visible on the leakage
detector and can only be adjusted in Seeker Setup.
Press the
SELECT
button (middle right) once to view the offset level settings. The first digit
of the high-frequency offset levels will begin to flash. To adjust the value of the selected digit
upward, press the
CHANGE
button (upper right).
Press the
SELECT
button (middle right) again to move the selection to the next digit and
continue this process until you are finished entering the offset values. The offset value for both
the high and low frequencies can be set anywhere from 20 to 60 dB.
Input Level Settings
The image displayed to the right shows the input level setting that
should match the transmit level of the Seeker HL Source Transmitter.
The source transmitter operates at two different output levels of 60
dBmV (120 dBuV) and 40 dBmV (100 dBuV), as indicated on the
label on the back of the device.
Example:
If the output level of the transmitter is set to 60 dBmV (120
dBuV), the input level of the leakage detector should be set to 120
dBuV.
Within the input level setting mode, the PK icon in the upper middle side of the screen flashes.
If the “Enable Meter Entry” checkbox is checked within the Seeker Setup software during
configuration, this level is adjustable on the leakage detector.
Press the
SELECT
button (middle right) five times to view the input level setting. The input
level setting will begin to flash. To adjust the value of the input level, press the
CHANGE
button
(upper right). The input level value can be set to 120 dBuV or 100 dBuV.
