Setting procedure
(1) Load the condition settings files from the PCMCIA card.
Condition settings files
Measurement procedure (
(1) Load the condition settings file for type T as described above.
(2) Connect to the zero controller with the (T) compensation leads.
(3) Use the voltage generator to successively input the reference voltage signal for each range to the 0˚C
reference temperature device (zero controller) according to the table below, then check that the level of
measurement is within the rating.
