740 Portable Suspended Solids
1 Introduction
1.1 General
The 740 Monitor is used for processin and displayin the output si nal from a Partech
sensor. It combines a clear display of the measured parameter, a simple user interface,
with ood flexibility to enable confi uration to satisfy the users needs.
1.2 Display
The 740 display indicates the measured value with lar e numerals for ood visibility
with an additional status line that shows the current settin s, battery status and any
faults that are present. The display has a backli ht to enable use of the monitor in low
li ht conditions and also has automatic contrast settin s.
The measurement title, units and display ran e can all be user set to suit the sensor
bein used and the application bein monitored.
1.3 Key Pad
A six key tactile membrane keypad is used for all confi uration and operation of the
740 Monitor; each key has a very positive operation enablin use even whilst wearin
loves.
1.4 Sensors
The 740 Monitor can be used with the Partech Soli-Tech 10 (ST10).
1.5 Manual Conventions
This instruction manual describes the confi uration and operation of the 740 Monitor
and where required includes some information re ardin sensors. It is therefore very
important that it is used in conjunction with the relevant sensor instruction manual. All
dimensions stated in this manual are in millimetres unless otherwise stated.
The manual has been written on the basis that the user has a basic knowled e of
instrumentation and an understandin of the type of measurement bein made.
Trainin in the use of the 740 Monitor can be provided by Partech, please contact
Partech for further information

2 Basic Operation
2.1 Switching On and Off
The 740 Monitor can be turned on and off usin the ON/OFF key. When the monitor is
turned on it displays a start-up screen prior to enterin Measure Mode. The instrument
can be switched off at any time by pressin the ON/OFF key.
2.2 Measure Mode
The normal operatin mode for the 740 Monitor is measure mode and this is active
when the measured value is displayed in lar e numbers. Whilst in measure mode the
display value is continually updated based upon the current sensor input si nal.
The display in measure mode also includes a status bar that scrolls throu h the status
of the battery, details of the instrument settin s and if the instrument is locked. The
status bar is also used to indicate any instrument faults that are present.

2.3 Measurement Cycle
The measurement cycle is carried out in the back round at all times when the
instrument is switched on re ardless of whether the instrument is in measure mode or
not. The monitor performs five measurement cycles per second enablin a response
time of one fifth of a second (with dampin rate set to Instant – see dampin ).
2.4 Display
The resolution of the displayed value is determined by the sensor ran e settin , such
that only sensible display values are indicated; the same ran e also determines the
calibration value ran e.
The display units and measurement title are user selectable and should be chosen to
suit the parameter bein monitored and sensor bein used.

2.5 Profiles
The 740 Monitor allows the user to define up to 10 Profiles, each profile will be based
on a preset confi uration which can be modified to suit the actual measurement
required.

3 Configuration
3.1 Menu Mode
To access the main menu, press the MENU key when the instrument is in measure
mode. Pressin the MENU key when the main menu is displayed will return the
instrument to the measure mode. When the main menu is displayed, the  keys can
be used to move the selection bar. Pressin the OK key will activate the selected item.
If the instrument is left in any display other than measure mode, it will automatically
return to measure mode after one minute has passed with no key presses. When a sub
menu is displayed, pressin the MENU key will exit the current menu and return to the
previous menu. If a menu consists of more than six items, UP and DOWN arrows will
appear to indicate if there are menu items above or below those displayed.
3.2 Data Entry
To provide the user with a simple interface, the 740 uses three methods of data entry
for the settin of all the user confi urable parameters. The various methods of user
data entry used on the 740 are described below:
3.2.1 User List Selection
This method of user data entry is used when a selection from a predefined list of option
is required such as sensor type, display ran e and backli ht mode. The list of possible
selections will be displayed and a small tick will identify the current settin . If the list
contains more than five items, small UP and DOWN arrows will appear on the display
to indicate there are more items than that displayed. To make a selection, the selector
bar can be moved usin the  keys, to select the required item. Pressin the OK key
will select the hi hli hted item and a small tick will appear next to it. Pressin the
MENU key will exit the list selection menu.

3.2.2 User Value Entry
When a numerical value is to be set, the current value will be displayed with a flashin
cursor. The ran e of adjustment of the value is predefined and therefore only values
within this ran e can be entered. To adjust a value, the  keys are used to select a
di it and the  keys are used to increment/decrement the di it. When the new value
has been set pressin the OK key will store it and exit from the value adjustment
display. To exit without savin chan es press the MENU key.

user defined measurement title and units. The text strin is displayed with a flashin
cursor indicatin the selected character. The  keys are used to select a character,
and the  keys to chan e the selected character. When all chan es are complete
press the OK key to store the text strin . To exit without savin chan es press the

4 User Profiles
Understandin the concept of profiles is key to the successful operation of the 740
Monitor. A profile is used to store the confi uration and calibration data for a particular
measurement. The 740 Monitor is capable of storin up to ten profiles, the actual
number required will depend upon the number of different measurements to be made.
Normally a separate profile is required for each different measurement to be made, for
example final effluent suspended solids and mixed liquor suspended solids.
4.1 Presets
To reduce the setup time of the 740 Monitor, several preset measurements are
available that the user can choose from when creatin a new profile. Each of these
presets contains confi uration and calibration data for commonly made measurements.
Note: The presets provide a fast route to co pleting the instru ent setup.
However as they use calibration data established fro reference easure ents,
it ay be necessary to carry out calibration to i prove upon the easure ent
accuracy.
4.2 Example Profile Configuration
Mr Bill Smith has a 740 Monitor which he uses at Charlestown Waste Water Treatment
Works to measure the mixed liquor suspended solids and the final effluent.
The monitor has been set up with two profiles (the remainin profiles are unused) as
shown below:
Profile 1 - Mixed Liquor Suspended Solids

5 Select Profile
To choose which profile to use, the Select Profile option is selected on the main menu.
The ten profiles are listed, if a profile has been setup the profile name is displayed
otherwise the profile is indicated as empty.
The active profile is indicated with a tick. To select another profile use the  keys to
move the hi hli ht bar then press the OK key. Information about the profile will be
displayed with a prompt to use the selected profile.
Note: If a profile na e was entered at the ti e the profile was setup this will be
shown, if a na e was not entered the default na e will be displayed e.g. Profile
One. Only the first fifteen characters of a user entered profile na e are
displayed.
