Configuring the Instrument
143
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.
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.
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.
12. Press
[MEAS]
to return to the measurement screen.
