Example #2: Programming a 3 point calibration for a 0-10mV input to a
recorder. The calibration points entered would be:
cal point #1 0 (%)
cal point #2 50 (%)
cal point #3 100 (%)
zero point 0 (mvolts)
full scale point 10 (mvolts)
Utilizing Calibration Points
Once calibration points have been enabled in the Setup Menu, they are
activated by simply pressing the INC or DEC key after selecting the
appropriate output function. The INC key steps forward through the
calibration points list, and the DEC key steps backwards. If you attempt
to step beyond the limits, the list will wrap around from the last to first
when incrementing, or the first to last when decrementing. To
automatically step through the selected calibration points, press the
AUTO Key. The steps will continue until the AUTO Key is pressed again.
Percent of Scale
The percent of scale function allows the user to specify a fixed
percentage that the output will change each time the INC or DEC key is
pressed.
Since the temperature scales have various ranges that would be
difficult to remember, the temperature functions are setup to change
by a fixed number of degrees. The range of values for percent are .01%
to 100.00%; the range of values for temperature are .1 degree to
1000.0 degrees.
The top line of the display lists the functions affected by the
increase/decrease value. The second line shows whether the value is a
percent of full scale or degrees. The current value is also shown.
