displayed.
Pressing F4 on the keyboard opens the Communications Setup dialog, tests for
communication with a logger, and displays the logger type and other data
For more information on the logger in use, click the Diagnostic button which
now appears. Additional data shown covers firmware version, maximum
permitted internal logger temperature, battery charge status, serial number and
temperature recording range. If a Transducer Interface is attached, current
temperature of the probes (updated once a second) is also shown – or open
circuit (*OC*) if no probe is attached; the temperature of the thermocouple
cold junction is effectively the current internal temperature of the logger.
Setting Frequency of Electricity Supply
To increase the efficiency of the logger's noise rejection, and thereby provide
more stable measurements, select the frequency of the local electricity supply
as follows.
1. In the Insight software, select Tools > Options and click the 'Logger' tab
and then the 'Advanced' button.
2. Select 50 or 60 Hz frequency. 50 Hz is most widely used, but 60 Hz is used
in North America, several countries in South America, and in Japan and
Korea.
