Setting procedure
(1) Load the condition settings file GL2CondVT.CND from the USB memory device.
Measurement procedure (
(1) Connect to the zero controller with the (T) compensation leads.
Connect the (T) compensation leads to the CH2, CH4, CH6, CH8 and CH10 input terminals.
(2) Use the voltage generator to successively input the reference voltage signal for the 0˚C reference
temperature device (zero controller) according to the table below, then check that the level of
measurement is within the rating.

(3) Connect to the zero controller with the (K) compensation leads.
Connect the (K) compensation leads to the CH3, CH5, CH7 and CH9 input terminals.
(4) Input the reference voltage signal for the 0˚C reference temperature device (zero controller) according
to the table below, then check that the level of measurement is within the rating.
