Viewing Advanced Multisizer Settings

2.

In the Waste Tank pane, the Set Vacuum to field displays the current Waste Tank vacuum
setting. Set this value to 6.00" Hg unless you are using an aperture tube that is 560 µm or larger.

3.

The Vacuum Tolerance: +/- field displays the vacuum deviation (in inches of mercury) that will
trigger the error message Check the Vacuum Regulator.

4.

In the Metering Pump pane, the Set Vacuum to field displays the current Metering Pump
vacuum setting. This value must remain at the default, 6.00" Hg.

5.

The Minimum Flow and Maximum Flow fields display the flow rates in mL/sec that will trigger
error messages. For more information, see

Flow Rate Error Messages

6.

The Pre-flow Stabilizing Time and Total Stabilizing Time fields display the time, in seconds, that
the Analyzer will use for stabilization before beginning particle analysis.

7.

The

button indicates that settings in this window are for viewing only. It is not

possible to change vacuum and flow settings unless you are running Service Mode (page

not possible to apply new settings unless you are running Service Mode (page

Flow Rate Error Messages

The default flow settings adjust for aperture tube size and are appropriate for most analyses. Under
certain conditions—if you are using an unusually viscous electrolyte solution, for example, or if you
have increased the vacuum for a large aperture tube—it may be necessary to adjust the flow rate to
avoid unnecessary error messages.

When the flow rate is too low, the Multisizer 4 software will display one of the following error
messages:

Flow Rate is too low, the aperture may be blocked
Flow Rate is too low. Unblock the Aperture?
Flow Rate and Pressure are too low, try unblocking the Aperture

When the flow rate is too high, the Multisizer 4 software will display the following error message:

Flow Rate is too high, there may be air in the system. Try Flush Aperture Tube and Purge
Metering Pump.

If one of these error messages appears and the system is functioning properly (the aperture tube is
not blocked and there is no air in the system), adjust the volumetric flow settings in the Sample
Delivery Settings window (see

Adjusting Volumetric Flow Settings

).

Adjusting Volumetric Flow Settings

Adjust Metering Pump flow settings if the Multisizer 4 software displays the following error
message while analyzing in volumetric mode:
