Semi-continuous Auto-measurement incl. data logger
A precondition for semi-continuous Auto- measurement is the option:
Automatic zeroing and calibration of the analyzer art. no. 64198.
The Auto-measurement must be activated by the operator in the meas-
uring window via the menu key. Please select Auto-measurement.
In semi-continuous mode, the minimum interval is 10 minutes.
Average values are not possible.
When the semi-continuous Auto-measurement is started, the following
procedure is started:
purging / waiting/ sucking in gas / measuring
The “purging” phase takes 2 minutes each time.
The "sucking in gas" phase has a duration of at least 3 minutes
The "waiting" phase depends on the duration of the zeroing.
At the first start, the duration of the zeroing process is assumed to be 2
minutes. With the 2nd zeroing the time is measured how long the zeroing
runs.
This will be considered in the next "waiting" phase.
In order to protect the electrochemical sensors, the valve is only switched to
"gas" during "gas suction/measurement".
Selecting sites
The storage location in the internal data memory is the currently selected
site. Select the desired site before you start the Auto-measurement. The site
can be selected in the Storage menu under Sites administration. Use the
RIGHT/LEFT keys to switch to the next or previous site.
For details on the Data Storage refer to the User manual, chapter 8
Data Storage, Page 44.
