flow rate of 1.0 cubic feet per minute. The sample time cannot be
changed directly.
11. Enter a value for the Sample Volume between 0.1 and 9999 mL. This
is the quantity of fluid that will be sampled in each analysis. This
value is preset to 5 mL if USP24<788>, JP<13> or EP<99> is
selected and a glassware check is being run. For MANUAL and
TIME modes, set the sample volume to match the sample volume
delivered during the run.
12. Enter a value for the Pooled Volume between 20 and 9999 mL. This
value is the quantity of fluid removed from the Pooled Containers and

analysis, the glassware is clean, and the water used for analysis is
free of particles. Sample Test refers to the testing of the Sample
Volume.
The Test Type field is available only if USP24<788>, JP<13> or
EP<99> is selected.
Set passwords and access levels
The counter has three levels of operator access: High, Medium and Low.
Operators with High level privileges can access all the functions
available to operators with Medium and Low access. Low level access
does not require a password.
On start up, an operator must enter a password when prompted by the
instrument. If the operator pushes only the ENTER key, or enters an
invalid password, the operator has only low level access.
Make sure that the date and time for the counter are correct before
access levels and passwords are set.
1. In the Password functions menu, select an option.
Option Description
SET LEVEL Sets the access level lower than the current level. This is the
only password button enabled for medium level operators.
SET Sets the passwords for high and medium level access. The
PASWD password must be typed in once, then typed in again for
verification. Passwords are alphanumeric entries of up to
16 characters.
SET Only available to high level users. Controls the functions
ACCES available to medium and low level operators. The medium
level operator has access equal to or greater than the low
level operator access. If a high level operator grants a low
level operator access to a function, the medium level operator
access is automatically enabled.
