3.7.4 Interface Settings
The Interface Settings sub-menu has an additional three sub-menus:
Temperature Difference
pH Set-up
Factory Diagnostics
3.7.4.1 Temperature Difference (offset)
The temperature difference function allows the user to fine tune the tem-
perature set point of the system. Although the temperature set point for
the system can be set in the Heat Menu there may be a small discrepancy
between the actual temperature of the system and the defined set point.
The user can adjust the temperature of each chamber individually to fine-
tune the temperature setting, so the exact temperatures are achieved in
each chamber. This is referred to as a temperature offset (TEMP OFFSET
ON CHAMBER). The SELECT and ALL functions are the same in this menu
as for previously described menus. Pressing ENTER will store the numbers
in memory for future experiments
3.7.4.2 pH Set-up Menu
The pH calibration is a 2-point calibration. In the pH set-up menu the two pH
values used for the 2-point pH calibration should be selected. The default
in the pH Calibration setup is the pH values 4 and 7. If using pH buffer with
different pH values than 4 and 7 for the pH calibration enter the appropri-
ate pH.
The temperature is an important parameter in the calibration formula and
is obtained automatically if the temperature compensation it is set to AUTO
as shown.
If MANUAL is chosen, a manually set temperature is used in the pH calibra-
tion formula, and the temperature probe is not used. In the MANUAL mode,
the temperature of the calibration buffer is measured with a thermometer
and entered manually in the Manual temp. Value line.
3.7.4.3 Factory Diagnostics
Entering Factory Diagnostics will display the Login code to diagnostics
window. This window is only for trained technicians and used for diagnos-
tics and troubleshooting purposes. The general user will not have access to
this window. Entering the proper five digit login code however will allow the
trained technician access to diagnostics panels that will provide information
during a malfunction, or mechanisms to change other settings controlled by
the onboard computer.
