Operation
Setting the data logger parameters
In the parameter setting mode, you select whether data
logging is to be interval-controlled, event-controlled or
manual. Press STO to access the logging functions.
To select interval-controlled logging of measured values,
press STO and set the interval in which the recording is
to take place using and . The interval range is between
5 seconds and 60 minutes. Default time (factory-set) is
2 minutes. After selecting your interval time, press STO to
enter the value.
With event-controlled data logging, a measured value is
not saved until it deviates from the last memory value by
the preset differential value. Using the time which is also
stored, you can determine when the value has changed.
The differential value is entered in the subsequent param-
eter-setting step.
Note
The differential value is always based on the currently
set measured variable (conductivitiy, salinity or TDS). This
means that if differential conductivity values are to be
logged, the meter must be set to conductivity measure-
ment prior to parameter setting and data logging.
With manual data logging, the measured values are saved
by pressing STO.
After selecting the above parameters, select “Continue”
or “Start” using the
▲
and
▼
keys and then press STO to
commence logging.
Note
The data logger is a ring memory, i.e. it does not stop
after reaching the last memory location (99). Recording is
automatically continued with memory location number
00. To avoid losing data by overwriting, download stored
data and clear the logger before beginning a new set of
data. Be aware of this when using interval-controlled data
logging.
