Filter
The Filter parameter allows the user to change the bandwidth of
the output signal. It functions as a low pass filter, meaning
frequencies above the selected value are attenuated. This allows
the user to reduce the amount of high frequency data on the
output signal (i.e., reduce noise) and effectively average the output
value. Selectable values are 500, 250, 120, 60, 30, 15, 8, 4, 1 Hz.
NOTE: Changing the Filter settings also changes the reception
error rate detection threshold. This means that using a lower Filter
setting may improve data integrity in an electrically noisy
environment (where RF interference is present).
Input AutoZero
The Input AutoZero parameter provides an easy way to
compensate the output for any offset from the gage or sensor.
When turned On ("Input AutoZero: On"), the existing input from the
TX10K-S becomes the input zero. Before adjusting the Gain,
apply the AutoZero to the input signal. In this way, the zero (0V)
output will not change when the Gain setting is adjusted. When
the AutoZero is off ("Input AutoZero: Off"), no offset correction is
applied to the output signal.
To turn the AutoZero On, press and hold the
ADJUST
▲ key for 2
seconds. To turn the AutoZero Off, press and hold the
ADJUST
▼ key for 2 seconds. In order for AutoZero to properly zero the
output, the displayed output number must be stable. Switching the
Filter to a lower frequency setting may help stabilize the signal to
enable an effective AutoZero. The Filter may then be returned to
its original setting for normal operation. The AutoZero function will
not work properly if there are 1) too many “Tx
Rx Data” errors, 2)
the signal from the TX10K-S is over or under range, or 3) the Input
parameter is not set to “Transmitter”.
