Setups required to use the logging function
(setting the log name, input channel, measurement interval,
and measurement period)
Settings relating to the logging function must be made here.
A convenient way to do so is to create a table of tags and logs, namely, a tag/log table. Once
you create a tag/log table and set it to the reference table, Thermo-Collector automatically
replaces abbreviated tag names* with more descriptive full names** when receiving the
measured data from a TM20.
* Abbreviated names are 8-digit names that can be displayed on the TM20 screen.
** Full names can be displayed on the PC screen without any limitation in length.

Setup contents
●
Log name
Put a title to each log. A log name can consist of a maximum of eight alphanumeric charac-
ters.
●
Input channel
Thermo-Collector has multiple input channels and probes for measuring temperatures of
substances in a vapor, solid, or liquid phase. Since the probe to be used depends on the
measuring object, it is necessary to set the available input channel on a tag in advance.
The following table shows the probe types and their corresponding input channels.
Probe type

Non-contact thermo probe
D
[TIP]
To plug a voltage output sensor into channel A or B, use a U-shaped omega connector.
●
Measurement interval
Set an interval at which the temperature is periodically measured. The interval can be set to
between 1 second to 24 hours.
●
Measurement period
Set a period through which the temperature is measured continuously. The period can be
set to between 1 second to 999 days.
