Figure 1.3 Setting the Spin Safety Threshold
2. Remove the sample, or activate the sample lift, and annotate the “empty” spin volt-
age.
3. Insert, or lower the sample, and switch on the spin (either from the BSMS panel or
from the Web server).
4. Repeatedly read the spin voltage and annotate the two values that can be read
while the sample is spinning.
5. Set the “sample down threshold voltage” to about halfway between the lower of the
two “black/white” spin voltages, and the “empty” spin voltage.
Everything is set correctly when the spin does not cut off during normal operation, but
cuts off immediately when the lift is activated.
Note: The “Spin DC Voltage Counter” sets the number of times the value has to be
below the threshold, before the safety shut off is activated. It should be set to 10 to avoid
the spin cutting off with just a single bad reading.
