System Mode
12
This allows backwards compatibility with software
written for earlier models of Palintest instruments.
In this mode, the PC requires installation of
a USB virtual COM Port driver, available from
www.palintest.com/know, and the availability
of software operating as a terminal server.
A large number of third-party software systems
are available to provide data upload and remote
control of testing using the COM port mode.
Please contact your local Palintest representative
for more details.
5.6 Units
The Pooltest 9 Bluetooth offers the choice of result
expressed in mg/l, ppm, mmol/l, µmol, g/l and µg/l.
Changing the result units will not affect the result log.
5.7 Dilution Factor
When samples are above the test range, indicated
by >> on the result screen, a dilution procedure
can be used. Setting Dilution Factor to On will
prompt the Pooltest 9 Bluetooth to automatically
request the dilution factor when carrying out a test.
Change the dilution factor by using the up/down
arrows or manually type the dilution factor. The
instrument will automatically correct the result
for the dilution and display the corrected result
(which will also be stored in the result log).
The maximum dilution factor permitted is 99.
If the calculated result exceeds the available number
of permitted characters >> will be displayed.
NOTE:
do not use sample dilution
when measuring pH or alkalinity.
5.8 DPD Range
The Pooltest 9 Bluetooth operates in a choice of DPD
ranges, depending on the pool treatment programme.
Two choices are available and only one range can
be used at any time:
0-5
the ‘standard range’ of 0-5mg/l (ppm) Cl
2
.
In this range the AP 011 and AP 031 DPD
reagent packs are suitable
0-10
the ‘extended range’ of 0-10mg/l (ppm) Cl
2
.
In this range the AP 013 DPD XF and AP
033 DPD XF/XT packs will be required to
carry out the testing.
The selected range of DPD will be indicated in the
Test List e.g. Test 001 Chlorine-Free/10 indicates
the extended range has been selected and the
DPD XF reagent should be used.
5.9 System Lock
To prevent unauthorised or inadvertent changes
to the System settings or log deletion a four digit
code can be used to lock several options.
The default code is set to 6812. To change the
System Lock code, follow the on-screen prompts
to choose a memorable four digit number.
When the System Lock is applied, the items
accessible within the System Mode are limited
until the unlock code is entered. Access is limited
to viewing the result log, adjusting the backlight,
contrast and Bluetooth settings.
5.10 Water Balance
Two options are available for the Test 77 Water
Balance scale:
Palintest
uses the simplified Palintest scale
which assumes values for Total
Dissolved Solids (TDS) and temperature
and removes the need to measure
these parameters.
Langelier
uses the results from a TDS/
temperature meter to calculate the
Langelier Saturation Index (LSI) value.
For more information, see both the test method on
page 24 and visit www.palintest.com\know for more
information regarding the importance of Water
Balance and the relationship between the two scales.
