Calibration procedures
4.4 Calibrating agitation speed
1. Touch the top of the Agitation module on the Touchscreen Console
Home screen to open the Agitation Settings screen. Touch
Calibration
.
2. A screen will appear prompting you to measure the actual motor
speed (in Hz) using a tachometer, and enter the speed in the field
provided. After entering the actual motor speed, touch
Done
.
3. A 1-point offset adjustment complete screen will appear when
calibration is complete. Touch
Done
in the lower right corner of the
screen to return to the Agitation Settings screen.
4.5 Calibrating mass
1. Touch the top of the Mass module on the Touchscreen Console
Home screen to open the Mass Settings screen. Touch
Calibration
.
2. Select the type of calibration you would like to use (
1-point
,
2-point
, or
3-point
).
3. The steps below detail the process for 2-point calibration.
Note:
1-point and 3-point calibration use the same steps, with
slight differences: 1-point calibration does not include step “b,” and
3-point calibration will repeat step “b” for the third calibration point.
a. After touching
2-point calibration
, the first calibration point
screen appears prompting you to enter the first mass sensor
value in kg. Place a calibrated weight—or an amount of liquid
through a calibrated flow meter—in the vessel, enter the sensor
value on the screen, and touch
Calibrate
.
b. A screen will appear for the second calibration point. Add a
heavier weight to the vessel. Enter the total mass sensor value
in kg, then touch
Calibrate
.
c. After the Mass Calibration Complete screen appears, the
calibration is complete. Touch
Done
in the lower right corner of
the screen to return to the Mass Settings screen.
