Trending:
In this menu, a graph is displayed of all the measurement values. There are two possibilities
in this screen:
1. Auto scale: Automatic scaling between the lowest measured value and the highest
measured value with a maximum value for the O
2. Fixed scale: A fixed scale with the minimum and maximum values that have been
selected for controlling the analog outputs concerned.
A trend line consists of a maximum of 150 measurement values. Trend lines can be displayed
for both the oxygen content and the temperature.
Operating hours:
In this menu, the operating hours of the sensor are displayed. A distinction is made between
measurement hours and standby hours.
Extremes:
The extreme values for the oxygen content and the temperature are saved in this menu.
Calibration:
The last three calibration dates of the O
parameters are stored in the control box memory. If a restore is given to a sensor, the last
calibration will be restored. This option is not functional if the transmitter box or the sensor is
exchanged in between two calibrations. (The calibration data doesn't match anymore between
the sensor and the control box)
Alarms:
A maximum of 50 alarms is saved in this menu, including the date and time. The user cannot
alter this menu. With a full memory the oldest alarm will be deleted and replaced by the most
recent.
Reset:
The Reset menu can be used to delete all stored measurements.
