Thickness Mode" on page 129 for details).
6. In the HOLD BLANK text box, configure the instrument to either continue to
show (HOLD), or not hold (BLANK) the last measured thickness and waveform
while a loss of signal (LOS) occurs.
NOTE
The MIN/MAX and HOLD BLANK functions are mutually exclusive. You must set
MIN/MAX to OFF in order to change the HOLD BLANK function. Similarly, you
must set HOLD BLANK to BLANK in order to change the MIN/MAX function.
7. In MEASURE RATE, adjust the measurement update rate (see "Adjusting the
Measurement Update Rate" on page 48 for details).
8. For single element transducers only, set AVERAGING to OFF in order to turn
thickness averaging off, set AVERAGING to ON to perform a running average of
the last five thickness readings, or set AVERAGING to On-QBar to display a
quality measurement Q-bar below the measurement screen, indicating the
stability of the averaged reading.
9. Set ID OVERWRITE PROT to ON (with the Datalogger option only) if you want
to see a confirmation message in the help bar when attempting to save a
measurement reading in an ID that already contains a value (see "Setting the ID
Overwrite Protection" on page 115 for details).
10. For single element transducers only, set QUICK SETUP RECALL to ON in order
to activate the quick recall of the first four custom setups by using a combination
of the [2nd F] and arrow keys (see "Quickly Recalling a Custom Setup for Single
Element Transducers" on page 184 for details).
11. For single element transducers only, set AGC to ON to configure the automatic
gain control (AGC) function to automatically bring all measured back-wall echoes
to the same amplitude.
TIP
The AGC function works well for most standard thickness gage applications, and is
turned on by default. In some thickness applications, the receiver gain is set at or near
its maximum value. In such cases, turn off the AGC function to prevent reading
instability.
