such as cast iron, or high surface noise materials such as aluminum,
this procedure may result in a decrease in gain. In the case of hot
materials with rough surfaces or other highly attenuating but low
noise materials, this procedure may produce an increase in sensitivity.
To Perform Automatic Material Gain Sensitivity Optimization:
Step 1: From the Measure mode, press [2
nd
F],[ENTER](GAIN
OPT). The gage will display 0.000.
Step 2: Use the [ ], [ ], [ , and ] keys to slew to the
approximate wall thickness. It is best to guess low if you are
uncertain.
Step 3: Couple the transducer to the material sample and press
[MEAS]. Optimization will be performed and the gage will
return to the Measure Mode. The gain flag will indicate that
the gain is not at default gain by displaying "GO" (Gain
Optimized).
Return to Default Gain:
Note: Return to Default Gain when the optional waveform is
active. Default Gain may be restored directly by pressing
[2
nd
F], [ ](Gain) and then [2
nd
F], [ ](Gain) again
and then the [MEAS] key.
4.5 Measurement Setup
The measurement setup menu allows the user to turn on/off many of
the additional measurement features of the MG2 Series gages.
Measurement setup features include:
• Meas Option (MG2-XT and MG2-DL only)
