Menu in Datalyse
The CBL 2 is connected to the pc with a TI-graph link cable. The cable must be gray, the black cable will not work! The black cable communicates bit wise using dtr, dsr, cts and rts. This requires extra programming not needed for the gray cable.
You can measure on the probes that comes with the logger: voltage, temperature, light irradiance and on the Range sensor. CBL 2 has auto detect for new Vernier-probes. Old Vernier-probes are connected using a converter cable from DIN to CBL. The CBL 2 will automatically calculate the correct value from the voltage of the probe.
When measuring normally the minimum time is 0.2 seconds and max number of measurements is 3000.
When scanning the minimum time is 0,00010 s and max number of measurements is 3000.
The CBL 2 has a number of advanced functions for calculation of data before sending them to the pc. These include:
Read Scan (Online)
In this menu point a scan is transferred to the table and the graph in Datalyse. CBL 2 beeps ready when the scan is complete. You can check the status of the scan in the memo and interrupt it if necessary.
Read List (Offline)
The CBL 2 can be set to measure offline. In Datalyse this is done by selecting measuring and choosing the trigger setting »Manual«. Then you start measuring in the field by pressing the Start/Stop-button on the CBL 2. Unfortunately the CBL 2 does not save sufficient information to tell if e.g. d/dt or d˛/dt˛ has been measured.
There it is recommended to select »Read List«, having one list read and written to the table in Datalyse. Then select Read List again until every list has been read, which is when the list read last is identical to the first.
When measuring offline it is recommended to log time as well. Otherwise you will not be able to draw the data points as a function of time!
Read Setup, example:
CBL 2 has auto detection
of connected probes but you can also use old probes. Their
calibration factors are read from the file »Vernier.ini«. See calibration of
probes with CBL.
