2. Wiring with the interior reference end compensation method (INT) is
adopted for thermocouples:
The same thermoelectric characteristics should be ensured for connection from the
thermocouple measurement end to the plug, that’s to say, the compensation wires
and plugs should be used as the same type as the “tyPE”, the extension type is
preferable. See F2 in the above drawing.
3.
Wiring with the manual reference end compensation mode (MAN) or the
external reference end compensation mode (EXT):
The thermocouple to the constant temperature oven is connected by compensation
wires; The constant temperature oven to the instrument is connected by pure
copper wires and plugs.
With regard to the external compensation mode (EXT),
a four-wire Pt100 platinum resistance is required to be inserted into the
constant temperature oven, and a four-wire plug is required to be connected to
the RTD socket of the instrument, which is shown as F3 in the above drawing.
Note 1:
If thermocouple plug and RTD plug are connected to sensor in the same
time, insulation between the sensors should be ensured, or the
measurement results will be affected.
Note 2:
If any signals exceeding 5V are input, the instrument will be damaged.
