FULL-SCALE OUTPUT IN ENGINEERING UNITS value
which you entered in Step 2.g will be displayed (having the decimal-
point precision specified in Step 2.d). If you now need to change this
number, you may use
and
as explained in Section 3.A to do so. Since
“ABSOLUTE TRANSDUC-
ER”
calibration was selected in Step 4.b, this is the instrument reading
in
ENGINEERING UNITS—normally other than VOLTS—that is to cor-
respond to a full-scale analog output of +5.000 volts.
Then press
TO AVOID POSSIBLE DAMAGE TO THE TRANSDUCER, YOU
SHOULD NOT ENTER A FULL-SCALE OUTPUT THAT IS GREATER
THAN THE TRANSDUCER FULL-SCALE RANGE VALUE ENTERED
IN STEP 4(AX).d.
The entered full-scale output should also be greater than 20% of the
value entered in Step 4(AX).d
, to avoid possible nonlinearity and hys-
teresis effects.
NOTE: The 3000PLUS will now calculate a MODULE SCALING FAC-
TOR (MSF)
from the three numbers you have just entered (as
explained in Section 4.E and Appendix B, the
MSF is used as a gain
factor for the instrument’s full-scale input range). If this calculation
yields a gain that is too low (less than 1.0000, given the
FULL-SCALE
RANGE
value established in Step 2.b), you will see a display of

If the calculated gain is too high (greater than 1.5999, given the current
RANGE value), you will see a display of
alternating with
Press
