security.
The instrument is available in different configurations (refer to Table 2 on
page 8). This manual supplies instructions for the installation of an
instrument with one syringe and one pump. Adjust the installation procedure as
applicable to accommodate the number of syringes and pumps in the instrument.
3.1 Installation guidelines
· This instrument is for indoor use only. · The mains plug must be easily
accessible so the power can be disconnected quickly
in case of emergency. · Protective earth ground (PE) connection is required. ·
Keep the instrument away from temperature extremes, including heaters, direct
sunlight and other heat sources. · Put the instrument on a stable and level
surface in a well ventilated place. · Make sure that there is at least 15 cm
(6 in.) of space on all sides of the instrument to
prevent electrical parts from overheating. · Do not operate or keep the
instrument in dusty, damp or wet locations. · Always keep the surface of the
instrument and all accessories dry and clean.

the personal protective equipment appropriate to the chemicals that are
handled. Refer to the current safety data sheets (MSDS/SDS) for safety
protocols.
16
Installation
CAUTION
Chemical exposure hazard. Dispose of chemicals and wastes in accordance with
local, regional and national regulations.
NOTICE
This is only applicable to instruments with two syringes installed. It is
recommended to install the applications (refer to Install the applications on
page 30) before installing the titrant. Applications using titrant from
syringe 1 are loaded on line 1 of the home screen (refer to Home screen on

arrow to set the option ON/OFF then push Done to confirm.
4.3 Install a balance
This accessory is used to automatically send accurate weights to the
instrument. The balance is a laboratory type balance and uses the RS232
communication protocol with no flow control. When a balance is connected, the
window shown at the end of a titration that lets users enter a weight, shows
the value from the balance. The balance automatically sends the weight and
unit to the instrument in textual format:
· Messages end with
1. Set the RS232 parameters on the balance to:
· 9600 baud · no parity · no handshake · 8 data bits · 1 stop bit 2. Connect
the balance to the serial port on the rear of the instrument (refer to
Instrument connections on page 8) using an applicable cable. 3. From the home
screen, select Settings > Options and make sure that the Balance option is
checked.

4.5 Install the syringe verification kit
The optional syringe verification kit enables the verification of the
dispensing system based on the ISO8655 standard. The test adds different
volumes of liquid on a vessel put on a balance. The weights are used to
calculate the real volume added. The real volume is compared with the nominal
volume. The results are used to calculate the error in the volume added and
the syringe precision. There are three verification modes available:
· Fully automated–The balance is connected to the instrument. The system makes
the additions and calculates the results.
· Partially automated–The balance is not connected to the instrument. The user
does the balance readings and the system calculates the results.
· Dispense only–The system only makes the additions. The user does the balance
readings and calculates the results.
The syringe verification kit includes all of the necessary items: dispensing
tips, tubes, syringe holder, pipette holder, support stand, software key and
label with the license number. Make sure to keep the label with the license
number. A license key is necessary to enable the syringe verification option
on the instrument. The first time the option is selected, the instrument shows
the MAC address and the Firmware version. Send the MAC address, firmware
version and the license number to the manufacturer or a sales representative
to get the license key. Note: The license key is only necessary when the
option is selected for the first time. Items to collect:
· Analytical balance with resolution 0.1 mg, repeatability 0.2 mg and
uncertainty 0.2 mg · Temperature sensor · Deionized water “quality 3” (ISO
3696)
Prepare the syringe verification kit as follows:
1. Put an empty beaker on the balance. Refer to the illustrated steps that
follow. 2. For the fully automated mode, connect the balance to the
instrument. 3. Install the support stand near the balance. Put the pipette tip
adapter above the
beaker on the balance. 4. Connect the tube from the pipette holder to the
syringe outlet port. 5. Connect the tube from the water bottle to the syringe
inlet port. 6. On the instrument, manually enter the temperature. As an
alternative, connect and
put a temperature sensor on the water bottle to get the temperature
automatically. Note: The temperature setting is necessary for the fully
automated and partially automated modes. The dispense only mode does not
adjust the temperature.

Appendix A Change application parameters
Parameter Name Advisable syringe
NOTICE
The applications installed on the instrument have been pre-defined to optimize
the measurement process. Changing these default application parameters will
have an effect on the measurement process and measurement results. Only
qualified personnel should change these parameters or use the instrument in
Expert mode. Refer to the application note before changing any parameters.
NOTICE
In Basic mode changes to parameters are secure. In Expert mode changes to
parameters are not secure and can cause the application to run incorrectly.
NOTICE
The Active parameter is available to change in some parameter groups. It
specifies if the method should be used during the analysis. Changing this from
Yes to No means that the method will not be used which will have an effect on
the measurement process and measurement results.
NOTICE
The Hide result parameter (e.g. R2 hide, R3 hide, etc.) is available to change
in some parameter groups. It specifies if the result is shown on the display.
Changing this from Yes to No means that the calculated measurement result will
not be shown. This will not have an effect on the measurement process and
measurement results.
The parameters available for change can be different for each instrument configuration and the application being edited. The parameters marked with an “x” are available for change.

Why can’t I load any applications
Wrong file placement on the USB storage device
The user is not in the home screen
Make sure that the file path on the USB storage device is correct
Push the Home key to make sure that you are in the home screen before
connecting the USB storage device
Why is the instrument not recognizing the applications USB storage device, even though I have removed and reconnected the device and I see the USB icon in the header bar
Reconnecting the device has been done too quickly
Remove the device and wait until the icon disappears from the header bar, then push the Home key to make sure that you are in the home screen before reconnecting the device
Question
Why does the volume delivered not correspond to the volume displayed
Cause
Table 26 Titration
The volume of the installed syringe is different from the syringe configuration
Procedure
Use the recommended syringe for the application and make sure the volume is
correct

Question
Cause
Procedure
Why is the equivalent point not being detected at the expected volume
Air bubbles are trapped in the tubes
Select the Purge option on the instrument to purge the tubes of air bubbles (refer to Prepare the instrument for measurement on page 30)
How can I remove an air bubble that is trapped on top of the syringe
Air bubbles are trapped in the syringe
Select the Purge option on the instrument to purge the syringe of air bubbles (refer to Prepare the instrument for measurement on page 30)
Why is titrant leaking along the sealing above the electrovalve
The tubes have not been correctly installed
Turn the tube connector until a “click” is heard
Why is titrant leaking along the sealing below the electrovalve
The syringe has not been installed tight enough
The electrovalve is leaking
Make sure that the syringe is installed correctly
Change the electrovalve as described in Replace the syringe electro-valve

On my two syringe instrument, why is the titrant not being delivered into the beaker but back into the titrant bottle
The procedure is not being done on the correct syringe
Select the Syringe activation option on the instrument, and Toggle the
syringes to make sure that the correct syringe is being used in the
application
The active syringe is not the correct syringe
Erase all the installed applications and install them again. The applications on line 1 will be allocated to syringe 1 and the applications on line 2 will be allocated to syringe 2. Make sure the titrant and installation is correct for the syringe (refer to Install the titrant and the reagent on page 16)
