Zero Calibration
To perform a zero calibration, click on the “Zero”
option. The circle will be filled in for the selected
option. The drop down list under “Range” will
allow the user to select the millivolt range of the
inputs being calibrated. When a range is
selected, the recommended value will also be
populated. For a zero calibration, the
recommended value is 0. The list of ranges is:
20 mV
40 mV
80 mV
160 mV
1.28 Volt
2.56 Volt
The recommended value can be changed either by using the up and down arrows to adjust the value, or
by clicking on the value, which will display the numeric keypad. The user can enter the new value in that
way. The user can also individually select each input (one through five) to calibrate, where Check = yes
(calibrate) and No Check = no (do not calibrate). Once an input is checked, its current value will be
displayed.
For a zero calibration, a value of 0 mV will need to be sourced to the input or inputs.
Click on the Calibrate button to begin the calibration.
A progress bar will be displayed along the bottom of the screen giving the progress of the calibration.
Span Calibration
To perform a span calibration, click on the
“Span” option. The circle will be filled in for the
selected option. The drop down list under
“Range” will allow the user to select the
millivolt range of the inputs being calibrated.
When a range is selected, the recommended
value will also be populated. For a span
calibration, the recommended value is 90 % of
the full range. For example, if the range is 80
mV, then the span should be 75. The
recommended value can be changed either by
using the up and down arrows to adjust the
value, or by clicking on the value, which will
display the numeric keypad. The user can enter
the new value in that way.
Note: If the user is
