DESIGNATION
it is recommended to name each channel (main unit A and Extension unit B) for an easiest reading:
1) Press on icon A or B according to the instrument you wish to rename.
2°) A keyboard appears, enter the new name.
3°) Save the new designation.

CONSULTATION/ MODIFICATION
CONSULTATION mode let the operator to check out all working parameters.
This mode is represented by the closed padlock icon.
To change the settings of the BAMOPHAR, you need to enter in the MODIFICATION mode.
This mode is protected by a password identical to the last 4 digits of the serial number.
On the main display, press MENU icon.
Press the padlock icon and type the 4 last digits of Serial Number.
To validate it, press "OK"; Device is now in MODIFICATION mode (padlock is open).
If the entered keyword is wrong, BAMOPHAR stays in the mode CONSULTATION.
After 30 minutes the mode MODIFICATION switches back to CONSULTATION mode.
Where can we find the serial number?
The serial number (SN) is written on the identification label of the device.
It appears as well in MENU, icon " i " (INFORMATION).

pH/ ORP SETTINGS
9.1
ELECTRODE CALIBRATION
For calibration routine, temperature displayed on main menu should be close to the real temperature of buffers.
• To avoid the mixing of buffer solutions, rinse the pH electrode with water each time you change the buffer.
• Never wipe the electrode.
• For a correct calibration, choose the buffer value in relation with the process (e.g. buffer pH 4.00 for a process with acids).
Press MENU and choose ADJUST ELECTRODE.
STANDARD 7.00 pH
Plunge the tip of the electrode in the pH 7.00 buffer solution (Ref 9011), then confirm.
Do not forget to remove the electrode protection (translucent cap).
ASYM. +00.00pH
Leave the solution for about 5 minutes in order to stabilize the pH 7 measurement, then confirm.
If the measurement for ASYM. (asymmetry) is too high, a message ERROR appears:
- Verify that the buffer in use is the right one.
- Verify all connections and cable.
- In case the trouble persists, change the electrode.
BUFFER 4 pH or 10pH
Once the pH measurement with buffer 7.00 is correct, rinse the electrode and plunge the
electrode tip in other buffer solution, or pH 4.00 (Reference 9012) or pH 10 (reference 9013).
Type the pH buffer value, then confirm.
SLOPE 100.0 %
Wait a moment for the slope measurement to stabilize, then confirm.
If the slope is weak (<70%), a message “ERROR“ appears.
In such a case, if the buffer is the right one and not obsolete, change the electrode.
DELAY 0000 Sec
When the slope is valid (70 to 110%), enter the delay while measurement and outputs stay
blocked at values, previous to calibration routine; then confirm.
SAVE ?
To record the calibration parameters, press the icon SAVE.
Do not forget to set up the temperature mode to its previous setting: manual mode (fluid
temperature) or automatic mode (Pt 100 sensor connected), see the menu TEMPERATURE.
