3.4 Input Setup
Setting A/E Mag and Zero for Air Gage
If the gage tooling is an airplug or air ring using an A/E module use the following
procedure to set zero and magnification using a set of max and min masters.
1) Press MODE until “LIVE RDG” mode is selected.
2) Load the
MAX master into gage position.
3) Refer to the master calibration report to determine the master value of the MAX
master.
4) Adjust the ZERO knob on the E8303 module until the digital display reads the master
value of the MAX master from the calibration report.
5) Remove the MAX master and load the MIN master into gage position.
6) Calculate the difference between the reading with the MIN master loaded and the
reading with the MAX master from step 4.
a) If the calculated difference is
less than the actual difference between the MAX and
MIN master values from the calibration sheet for the check being setup, the
magnification needs to be increased. This is done by
turning the mag knob
clockwise .
b) If the calculated difference is greater than the actual difference between the MAX
and MIN master values from the calibration sheet for the check being setup, the
magnification needs to be decreased. This is done by
turning the mag knob counter
clockwise .
NOTE: Use a factor of 3X for adjusting the display readings. For example: If the
displayed reading is +.0005 and the calibrated value is +.0001 the difference is .0004
greater. Therefore, you turn the
"MAG" knob counter clockwise so that the reading
changes by .0012.
IMPORTANT: THE DIRECTION YOU TURN THE MAG KNOB DETERMINES
WHETHER YOU ARE INCREASING OR DECREASING THE
MAGNIFICATION. YOU SHOULD BE CONCERNED WITH HOW MUCH THE
DISPLAY CHANGES, NOT THE DIRECTION THE NUMBERS CHANGE!
For example, for the above example after turning the mag knob the displayed reading
may be (+.0005) + (.0012) = +.0017 or it could read (+.0005) - (.0012) = -.0007. This
depends on the polarity of the check.
7) After adjusting the mag knob, turn the zero knob in the same direction as the mag knob
to adjust the displayed reading to equal the deviation of the MIN master value on the
calibration sheet.
8) Remove the MIN master and load the MAX master onto the gage.
9) Repeat steps 3 through 8 until the displayed readings for the each master corresponds to
the max and min master values on the calibration sheet for the check being setup.
