6.
Run wire over pulley.
7.
Attach the 50g hook weight. Add additional 50g (for total of 100g) to the
hook weight.
8.
Start the motor. Motor will make 1 turn at low speed to initialize.
9.
Remove hook weight. 0g should now be on the string. Wait 10 minutes to
allow for motor warm-up. Do not stop motor during GEL calibration.
10.
On the touchscreen in the box labeled LOW DATA POINT input 0 on the
touchpad. Wait a moment for stabilization and select SAVE LOW VALUE.
11.
Carefully replace the hanger and 550g weights for total of 600g. Steady the
load on string; make sure there is not excessive movement. Wait 10 minutes
to allow the motor to warm up.
12.
On the touchscreen inside the box labeled HIGH DATA POINT input 600
on the touchpad. Wait a moment for stabilization and select SAVE HIGH
VALUE.
13.
On the bottom of the screen, ensure that the CALIBRATED VALUE is
reading 600g ±25 and press SAVE.
14.
Remove the weight and the string, calibration is finished.
Hysteresis is introduced when the torque is suddenly changed by
a large amount. Use care when removing/adding weight to
system. If calibration result is unsatisfactory, repeat with care and
allow motor to warm-up for a longer period. This warm-up time is
necessary as the motor has not been running. During a test, the
motor runs to simulate placement before the gel strength
measurement is made. This is similar.
