Press the ENTER key to start the motor and advance to the calibration interval count down screen. The default
interval will be 60 seconds. Pressing the ENTER key will terminate the calibration interval and take the user
immediately to the next screen. All other keys abort the calibration.

Based upon your drawdown interval and volume dispensed, observe the final flow rate on your flow meter at the
end of the interval as it must be entered in the next step.

Set point Calibration and Range Setup
Set point calibration and range setup will allow the user to scale and calibrate the 4-20 mA current input for speed
or flow, depending upon whether the system is open or closed loop. This calibration and setting of range can be
done wet or dry. To perform a
Wet
calibration the signal-generating device must be active and capable of
generating the full range (4-20 mA) of current input signals.
Dry
calibration requires no input signal.
To perform a
Wet
set point calibration, you must first correctly wire an external current signal source, to Analog
Input #1. Refer to
Section 5.3.3.7.2 Set point
(Analog Input 1).
Set point Range/Calibration for Open Loop Systems (Speed Control)
Set points, applied remotely to Analog Input #1 are used to
adjust motor speed in RPM
when the system is
configured for open loop speed control. In the example shown below the user has scaled/calibrated the 4ma signal
to correspond to 180 RPM and 20 mA to correspond to 1800 RPM. This scaling configuration uses the full range of
pump motor speed available and maximizes the available pump flow rates.
