Calibration
From this pop-up window, the Supervisor can calibrate the selected channel by setting the high
point or low point or both as shown in the following example:
Figure 47–Analog Inputs calibration example
Tap to Cancel or proceed through the screens in the example above. Apply or Discard the
calibration information as desired.
NOTE: a more detailed method of procedure can be found by visiting the Alpha
website at www.alpha.ca. Look under the Support menu item!

Static Calibration
Static calibration enables the Supervisor to calibrate controller analog inputs without the need
for a live signal at the input. This is especially useful for calibrating current inputs for systems in
the field. See Figures below:

Definitions
Load Voltage — The discharge voltage.
Load Current — The discharge current.
Battery Voltage — The charge or system voltage.
Battery Current — The charge current.
AC Mains — The average rectifier input voltage. AC Correction appears when AC Mains is
selected.
Total Rectifier Current — The sum of rectifier output currents.
Battery Temperature — The average of enabled sensors (if temperature sensors agree within
5%) or the peak value of enabled sensors (if temperature sensors do not agree within 5%).
Battery Run Time — The estimated time remaining before LVD.
Battery Capacity — A battery’s estimated ability to store charge.
Battery Depth of Discharge — An estimate of the energy removed from a battery during a
discharge.
Converter Load Voltage — The converter output voltage.
Converter Load Current — The converter output current.
The table below summarizes the default controller signal equations:

AC Mains Voltage Correction – provides the means to apply a correction factor to the reading
coming from the rectifier. There are correction factors for each ac input phase and for the
combined average ac voltage.
