To set the Alarm limits
1.
Select MENU/UTIL/ALARM LO LIMIT or ALARM HI LIMIT
2.
Press ENTER to display the Digits Edit Box and adjust to the desired value
3.
Press OK to confirm or ESC to cancel.
15.3 POLARITY
Your gauge is equipped with an option to select the polarity, or phase +/- of the waveform.
For instructions on when to adjust the polarity, see “Interpreting the Waveform” on page 28.
To adjust POLARITY:
1.
Set the measurement screen view to RF
2.
Select MENU/TUNE/POLARITY
3.
Use LEFT and RIGHT to toggle POLARITY between NEGATIVE and POSITIVE
4.
Press MEAS to return to the measurement screen.
15.4 PULSE WIDTH
Your gauge has an adjustable pulse width option. Pulse width refers to the duration of time the pulser is
switched on. Pulse width determines the amount of energy transmitted into the material being tested.
There are three pulse width options:
Spike
The Spike option is used for high resolution and general applications and can be considered as the standard
setting.
Thin
When additional energy is needed for more penetration, the Thin option may be necessary.
Wide
When even more energy is needed for more penetration, the Wide option may be necessary.
High frequency applications, where resolution is a requirement, may require the Spike or Thin settings to
achieve optimal results. Low frequency applications, where more penetration is a requirement, may require
the Thin or Wide settings, offering increased penetration. The variety of transducer frequencies and
diameters used in conjunction with the pulse width setting, enable you to fine tune the gauge to your
application needs.
To adjust the Pulse setting:
1.
Press MENU/TUNE/PULSE
2.
Use LEFT and RIGHT to adjust the value of PULSE (SPIKE, THIN, WIDE)
3.

16 MEASUREMENT - RECORDING YOUR READINGS
Your gauge is equipped with a data logger - an essential feature for improving the efficiency of product
inspection. With a data file open, all your readings values are saved into the file, therefore eliminating the
need to manually record measurements during the inspection process. Once all the measurements have
been taken, the gauge can then be connected to a computer or serial printer to save and print the results
of the inspection.
16.1 ABOUT THE DATA LOGGER
With a data file open, as you take measurements, the measurement data is stored in a group in the gauge
memory. A group can have up to 250 bolts, each bolt containing one reference length, and up to 51
elongations. The location in a group is specified by giving a row and column coordinate. The rows are
numbered from 1 to 99 and the columns are labelled from A to Z, then AA to ZZ giving a maximum of 52
possible columns. You should always save the reference length in column A.
