5.5 Menu topology
The device has three operation modes:
• Auto (AUTO): normal measuring mode
• Calibration (CAL): mode for physical calibration
• Configuration (CONFIG) mode for customer-specific adjustments and offset calibration
You can enter the calibration mode and the configuration mode with the help of the
correspondent main menus. Each main menu has a set of submenus.
Entering, navigating within and leaving a main menu:
• Press the button MODE/EXIT until the arrow on the left side of the display appears in front of
the abbreviation of the desired main menu (in the normal measuring mode: 1 x = CAL,
2 x = CONFIG).
i You are now in one of the two main menus.
• You can move through the submenu items by pressing ^, in the submenu you can choose the
different options.
• You can always leave the submenu level and go back to the normal operation mode by
pressing the button MODE/EXIT.
5.6 Calibration mode (main menu)
The manufacturer calibrates and tests every device before it leaves the factory. Therefore you
can use the device directly out of the box. Under normal conditions the manufacturer
recommends a recalibration every three months. Also be aware of the following device
properties:
INFORMATION!
Note that you can change settings, i.e. values and options, with the help of ↑ or ↓ upwards and
downward. But you can only move through the menus in one direction. If you want to go back, you
have to leave the main menu by pressing MODE/EXIT and enter it again as described above.
INFORMATION!
• During calibration the fan inside the device does not run to extend the life of the desiccant;
the fan turns on again during each calibration countdown, after returning to the normal
operation mode ("AUTO") or after 5 minutes, whichever comes first.
• While in calibration or configuration mode, the device has a time-out function; it
automatically returns the device to the normal operation mode ("AUTO") after a 15 minute
period of inactivity.
• While in the calibration or configuration mode, the relay contacts hold at the last valid
condition and will not change state.
CAUTION!
The desiccant pouch may become prematurely saturated if the measurement chamber is
permanently uncovered; therefore keep the chamber covered during calibration and replace the
ultrasonic cuvette immediately thereafter.
