• Observe polarity
• For extension, use a compensation cable suitable for the thermocouple used
• The eventual shield must be well earthed at only one end
• For 3-wire connection, use wires of same section (min. 1 sq.mm)
• For 2-wire connection, use wires of adequate section (min. 1.5 sq.mm.) Note: with a 15 m. probe to controller distance and a 1.5 sq.mm. section cable, the error is about 1°C
