a) Positive signal polarization
Suppose we test a probe (load cell) with sensitivity of 2mV/V, powered at 10V.
The input signal range is 0 to 20mV. From unloaded to loaded cell you should see a value from 0 to 1000.
Set scale limits: L.S. = 0; H.S. = 1000. Calibration procedure: U.C. = 3.
Phase F1: unload the cell (equal to applying input voltage of 0mV). Wait 2 seconds for the signal to stabilize. Press key F.
Phase F2: load the cell with a sample weight: for example, 80% of total weight (equal to applying input voltage of 80% of
20mV (2mV*10V) = 16mV). On display, set a value equal to 80% of H.S. = 800.
Press key F.
Phase F3: unload the cell (equal to applying input voltage of 0mV). Wait 2 seconds for the signal to stabilize. Press key F
(calibration finished).
b) Suppose we test a probe (force sensor) with sensitivity of 2mV/V, powered at 10V.
The input signal range is -20mV to 20mV. From maximum compression to maximum traction you should see a value from -
1000 to 1000. Set scale limits: L.S. = -1000; H.S. = 1000.
Calibration procedure: U.C. = 4.
Phase F1: do not apply any traction or compression to the sensor (equal to applying input voltage of 0mV).
Wait 2 seconds for the signal to stabilize. Press key F.
Phase F2: apply compression equal to 80% of total compression (equal to applying input voltage of 80% of 20mV
(2mV*10V) = 16mV). On display, set a value equal to 80% of H.S. = 800.
Press key F.
Phase F3: do not apply any traction or compression to the sensor (equal to applying input voltage of 0mV).
Wait 2 seconds for the signal to stabilize. Press key F (calibration finished).
