Instruments
2.3.1 - Thermocouple Connections
Connect the thermocouple to terminals 2(+) and 3(-) as shown in figure 4.
In order to reduce the error due to cold junction compensation, use thermal paste in
the rear (from the terminals where the thermocouple is connected to the cold junction
sensor). Use appropriate compensating cables with the same material of the
thermocouple in order to connect it to the instrument. Check if the thermocouple polarity
is equal to those of the terminals.
2.3.2 - RTD Connections
The 3-wire RTD is connected to terminals 1 and 3, and the compensation wire is
connected to terminal 2.
Use wires of same material, gauge and length on all 3 for compensating resistance.
The maximum resistance of each connection wire must be 10 . Use 18 AWG wire
(minimum) for distances up to 50m and 16AWG for distances greater than 50 m.
