4.5 [ESB]:[0,1,2,*3,4,5]
The ESB (Error Sensitivity Bath) setting sets the error sensitivity level
for bath sensor runaway detection. This is designed to detect when
the bath sensor accidentally falls out of the bath, or is removed while
changing cells/dishes. Setting it to 0 disables the error detection
completely, and 1 is the least sensitive setting (so errors will not show
up unless the bath sensor cools significantly when it’s not expected to.)
Setting the value to 3 results in nominal sensitivity, and setting to 4 or
5 will make the error detection more sensitive, allowing the controller
to detect that something may be going wrong more quickly, but also
increasing the chance that it gives false-positive errors when the bath
sensor warms and cools slightly during normal testing.
4.6 [ESF]:[0,1,2,*3,4,5]
The ESF (Error Sensitivity Flow) setting sets the error sensitivity
level for stopped flow detection. This detects when the bath sensor
cools slowly over a long period of time when the controller wouldn’t
expect it to do so (usually because perfusion flow stops). Setting it to
0 disables the error detection completely, and 1 is the least sensitive
setting with the error enabled. Setting the value to 3 results in nominal
sensitivity, and setting to 4 or 5 will make the error detection more
sensitive, allowing the controller to detect that something may be
going wrong more quickly, but also increasing the chance that it gives
false-positive errors when the bath sensor warms and cools slightly
during normal testing.
4.7 [SAFE]:[50.0…85.0]
The SAFE parameter adjusts the maximum temperature limit for the
heater. This is the upper limit for the safety temperature at which the
heater power is turned off, no matter what. The safety temperature
may continue to rise above this maximum temperature as heat
continues to spread in the QuickStage or inline heater after the power
is shut off, but no current flows to the heater transistors when the
system is above this maximum temperature and the yellow “Max
Temp” LED is illuminated. Default is 75.0˚C.
4.8 [Curr]:[0.5…1.2]
The Curr (Max Current) parameter sets the maximum current (Amps)
that the controller outputs per channel at the maximum software
command. This is an approximate upper limit, and the heater channel
currents will typically be slightly below this upper maximum during
operation. Default is 0.9 Amps. Using a lower maximum current
setting slows the heating rate and may improve performance if there
