the input accurately and the display changes from one reading to

the next at the voltage half way between the two values. Hence,

with dropping voltage the display will change at

4.95 V from 5.0 to 4.9V.

Lower-limit calibration. This is what you may choose to set if you

want the voltage alarm to trigger as soon as that voltage is reached.

Using this approach, at 4.90 V the display will change

from 5.0 to 4.9V. In practice, flight pack and receiver voltage alarms

are intended to alert you to when the voltage has dropped to a critical level. Lower-limit calibration

will do that; whereas mid-point calibration will not trigger the alarm until the voltage has dropped by

another 0.05Volts.

Bottom line: Use lower limit calibration to achieve most accurate alarms.

Setting lower-limit calibration is easy. For example, with a known voltage of 5.00V, adjust the

calibration until it is just flickering between 5.0 and 4.9V. Mid-point calibration is set by putting the

pot halfway between where the display flickers at the lower and

upper value. The values used are just examples for illustration, and

the principles above apply to whatever actual voltage you are

calibrating against.
