Checking the Data
Thermocouple probes are generally reliable, but damage resulting from
inappropriate use or handling can produce erroneous readings. If you suspect
that invalid data may have been introduced into your temperature profile
(paqfile), select the View Data tab in the Insight software’s Analysis Window to
view the raw data as downloaded from the logger. The various types of invalid
data which may be contained in a paqfile are shown in the analysis grid as
follows.
*OC* Open circuit.
*NA* Telemetry data not received.
