11. 001010 A APPENDIX C Determining Proper Span Gain The Span Gain parameter specified in F2 of the Setup Menu is directly related to the A D integration time Therefore the lower the number the higher the span gain value to use in the Setup Menu for F2 The first involves looking up a value in the table below saving that value then calibrating the system measurements per second Disregarding digital filter length a span gain of 25 produces about 25 to 30 measurements per second while a span gain of 200 produces only about 3 or 4 measurements per second If the first step does not yield a successful calibration then the second step allows the technician to view the actual internal count to determine the proper value for the span gain and check the system for linearity There are two steps to determining the proper To determine the initial value for span gain in the setup menu 1 Determine the number of desired external graduations and choose the corresponding value under the number closest to your full scale input range in millivolts 2 Enter the Setup Menu and save this number for the Span Gain parameter in F2 3 Performa system calibration If the calibration proves unsuccessful or you wish to view the internal count proceed to the next set of instructions To view the internal count during the calibration procedure 1 Enter the zero calibration menu F16 and follow steps 1 to 3 but do not save the zero point 2
