Settings General settings for the set
GLP on
off
Function to check whether the measuring
heads have a valid calibration.
When the sample is being registered, mea-
suring heads without a valid calibration are
rejected if the GLP function is active.
AutoTemp on
off
Function to control the temperature adjust-
ment. Measurement is started automatically
(at least 1 hour, at most 3 hours after the
OxiTop
®
-IDS measuring head is started).
Pre-tempering the samples to exactly 20°C
is not required.
The samples can be inserted with a tem-
perature in the range of 15°C ... 21°C. The
AutoTemp function takes over the tempera-
ture control.
Alarm diff. pressure
(Only for Measuring
mode: Pressure p)
50 ...150 ... 500 hPa Difference pressure (negative or positive
pressure difference compared to the start
pressure). If it is exceeded, the meter marks
the sample with an asterisk (!).
The warning when the specified Alarm diff.
pressure is exceeded is triggered when:
– the measurement data have been trans-
mitted to the meter and
– the measured value that was last stored
by the OxiTop
®
-IDS measuring head
exceeds the difference pressure
