The Mixer Stir Bar Auto-Recovery option on the Pumps/Motors page
uses Analog Input 4 to monitor the mixer stir bar. If the stir bar is in an
out-of-control state, the mixer motor is stopped briefly and then restarted
at a speed 5% slower than before the auto-recovery occurred. To disable
auto-recovery, select
No for this option.
You can use the controls on the SP ePanel in Chromeleon 7 to turn the
mixer on and off and to set the speed.
Heated Dilution Vessel (Option)
The temperature of the heated dilution vessel can be set to between 15 °C
and 40 °C. Specify the temperature in the Chromeleon 7 Instrument
Configuration Manager on the
Temperature page or in the Chromeleon 7
instrument method.
3.5.3 Dilution Pump
The dilution pump (P/N 068561) (see
Figure 3-6 ) uses a stepper motor to precisely
deliver diluent (typically deionized water)
through the metering valve to the dilution
vessel. The pump can deliver from 0.1 mL
to 250.0 mL.
The pump flow rate can be set to between
0.0 mL/min and 15.0 mL/min (the default is
15.0 mL/min). You can change the default
flow rate in the Chromeleon 7 Instrument
Configuration Manager on the
Pumps/Motors page.
