When verification of thermocouple inputs it is necessary to take into
account that cold junction compensation is perform inside of
Multilogger, where temperature is somewhat higher than ambient
temperature on the outer connector. This fact can sometimes cause
problems when performing verifications using the electric simulators of
the thermocouples. The best way is to do the temperature verification
together with the thermocouple.
Recommendations for periodical inspections ___________
The manufacturer recommends to perform regular inspections of the
system, into which the Multilogger is included. The interval and range
of the inspections depends on the particular application. The following
inspections are recommended for stationary installations:

metrological verifications

regular revisions and inspections subject to the intervals specified
in the corresponding standards

assessments of all problems that occur since the last inspection

visual inspection of the device and checking of the connectors

device functionality inspections (i.e. the functions used for a given
application):
a) verification of data transfer to computer
b) verification of alarms - change input value to activate
alarm and check display message
c) check the battery voltage (in device menu)

Verification of cabling - check the connection quality of cables,
check visually entire cable length for damage and the route of
cables for interference, especially whether some parallel power
wires are not near.

Visual inspection of sensors - perform their visual inspection and
make sure no water has leaked inside the sensors; moreover, verify
that their locations are suitable from the perspective of measuring
accuracy as well as possible interference.

Make a verification protocol.
