4.0 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 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.
4.1 QuadoptiX™ Technology
The
Palintest Compact Turbimeter
utilises
QuadoptiX™
technology for turbidity
measurement - a sophisticated optical approach
designed to ensure turbidity measurements
are as accurate and repeatable as possible in
even the most challenging circumstances.
Turbidity measurements are carried out by analysis
of light scattered at 90° to the incident light
(nephelometric measurement) at levels below 40NTU.
Above 40NTU 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.
4.2 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 Section 4.4). The initial default setting is
ON
.
After initialisation, 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 Section 4.5).
2 Calibration
- Choose either SDVB, Total
Suspended Solids or to Restore the factory
calibration values (see Section 4.7).
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 Section 4.4).
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’
button to return up a level.
4.3 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.
