INTRODUCTION
The Compact Turbimeter is the latest addition to the
Palintest Compact Meter range which includes
photometers for chlorine, ozone, chlorine dioxide and
ammonia.
The Turbimeter operates according to the ISO 7027
method for measurement of turbidity, utilising two NIR
light sources at 860nm as part of the QuadoptiX™
optical system.
The Turbimeter is provided in a hard case with
accessories and standards to support effective use of
the instrument.
For technical support or to report issues with this
product please contact Palintest or your supplier.

QUADOPTIX™ TECHNOLOGY
The Palintest Compact Turbimeter utilizes QuadoptiX™
technology for turbidity measurement –a sophisticated
optical approach designed to ensure turbidity measure-
ments are as accurate and repeatable as possible in
even the mostchallenging circumstances.
Turbidity measurements are carried out by analysis of
light scattered at 90° to the incident light (nephelometric
measurement) at levels below 40 NTU. Above 40 NTU
the recommendation is to measure also at 180° to
‘compensate’ the 90° readings.
QuadoptiX technology uses two independent sources
and two independent detectors to provide effectively
four entirely autonomous measurement systems in the
same instrument, allowing multiple validation of all
results for greater accuracy.

START-UP AND START PAGE
To switch the unit on, press the POWER button and
release. An audible beep will confirm the instrument is
on. Switch off by holding the POWER button for 1
second.
The LCD screen is provided with a backlight option that
can be set to on/off in the ‘System’menu (see Page 9).
The initial default setting is ON.
After initialization the Start page will appear and
display, initially defaulted to Mode screen and showing
three options:-
1 Reading –Select the mode to measure turbidity or
suspended solids (see Page 12).
2 Calibration –Choose either SDVB, Total Suspended
Solids or to Restore the factory calibration values (see
Page 16).
3 System –view or set Log (result and calibration),
Operator ID, Sample ID, Units, Language, Set
Time, Set Date, Date Format, Software Version and
switch the backlight on/off (see Page 9).
The option to change the Start page is available in the
‘System’ menu, allowing the user to choose to start in
the default mode above, normal measurement mode
or the last measurement mode used.
Navigation through Menus is carried out using the
Up/Down buttons, using the OK button to select or the
Back to return up a level.

Battery Life/Replacement
Your Compact Turbimeter is supplied with fresh batteries
that will be suitable for at least 150 hours of use.
Changing batteries is carried out through the
compartment on the rear of the instrument. Two ‘AA’
1.5V batteries are required. Current battery status is
displayed on the screen to assist in power management.
The Turbimeter has an auto-off function to save power,
automatically switching off the meter after five minutes
of inactivity.
A back-up battery is located on the PCB to store all
user data including the last mode used for reading.
Replacing the AA batteries will not lead to settings or
calibration data being lost.
If battery power is insufficient for effective analysis the
Turbimeter screen will show Error 110: Battery Low
and advise to change batteries. The battery icon will
also show ‘Empty’ status.
If battery power is insufficient for any operation the
Turbimeter screen will show Error 111: Battery
Critical and automatically shut down.

SYSTEM MENU
The System menu allows the user to set the Compact
Turbimeter preferences and review results and
calibration data.
Log
Select ‘Results’ or ‘Calibrations’.
Once the log has been chosen, select ‘View’or ‘Clear’.
The ‘Readings’log holds up to 100 data points with
date, time, Sample ID, Operator ID, Reading Mode and
Result. The oldest result will automatically be
overwritten when the log is full.
The ‘Calibrations’ log stores the date, time, method and
Operator ID (if set) for the last 12 good calibrations.
To view data select ‘View’ and use the up/down
buttons to scroll in either direction.
Use ‘Clear’ in either log to delete the entire log. Select
‘Clear’then ‘Yes’in the following screen to delete.
Operator ID
Optionally select or edit the username using
alphanumeric characters.
To create a new Operator ID select a blank line and
press ‘OK’
Press ‘New’to create the ID.
Use the Up/Down buttons to show/change characters.

When the correct character is shown, press and hold
the [+] keyfor one second to move to the next character.
Correct mistakes byholding the [Del] keyfor one second.

Select ‘OK’to accept the entry or Edit to modify the
entry.
To modify or delete an existing Operator ID, highlight
the ID and select ‘Edit’ Choose either ‘Edit’ to modify
the existing entry or ‘Delete’ to remove it from the list.
Deleting the Operator ID will not affect results stored in
the log.
Up to 12 Operator IDs can be stored and recalled from
memory as required.
To return to the System menu, either select the
Operator ID required using ‘OK’ or highlight a blank
entry (if one is available) and press ‘Back’
Sample ID
Optionally set the Sample ID using the same method
as Operator ID.
Up to 24 Sample IDs can be stored and recalled as
required.
Both Operator ID and Sample ID are stored in the log
with result and calibration data.
