6.5 Using the timer
The Timer module on the Touchscreen Console allows you to set a
timer to monitor the length of time that the S.U.M. has been mixing.
To use the timer, locate the Timer module on the Home screen of the
Touchscreen Console. Touch
Start
. The timer will begin counting up
from zero, and will continue until you touch
Stop
. Touch
Reset
to revert
the counter to zero.
6.6 Monitoring and controlling functions
6.6.1 Mixing
You can monitor the mixing speed during operation by using the
Agitation module on the Touchscreen Console. The Agitation module
on the Home screen shows the current mixing speed, as well as the
setpoints that were entered during module configuration. To calibrate
the agitation speed, see section 4.4 in this publication.
6.6.2 Adjusting pH and conductivity
The Touchscreen Console allows you to monitor the pH and
conductivity levels of the solution while it is mixing. On the Touchscreen
Console Home screen, the pH and Conductivity modules show the
current values read by the system. Adjusting these levels requires the
use of pumps that have been set up for acid, base, or saline buffer
solutions. Use the following steps to adjust the pH and conductivity
levels.
1. Before adjusting pH or conductivity, ensure that the probe you
are using has been properly calibrated and correctly inserted
into the probe assemblies. See sections 4.2 and 4.3 for pH and
conductivity calibration information.
2. On the Touchscreen Console Home screen, touch the top of the
Pump
module that has been assigned to the buffer you would like
to deliver, such as acid, base, or saline.
3. Select
Add Bolus
. On the screen that appears, you will be
prompted to enter the desired units, fluid amount for the pump
to deliver, and the amount of time the delivery should take (bolus
delivery duration). The “Setpoint flow rate” field should automatically
populate after the fluid delivery and duration have been entered.
Note:
If a time or fluid amount is entered that is greater than
the values to which the pump has been calibrated, the fields will
