A thermocouple has polarity. Connect thermocouples to the terminal
block correctly using compensating conductor that are suitable for
the thermocouples.
Be sure to use the cold junction compensator (no. 13 and 15) pro-
vided with the E5ZE. The lot and serial numbers of the cold junction
compensator must be identical to those of the E5ZE. Do not touch
the cold junction compensator while operating the E5ZE.
The number of each of the above thermocouples is a point number.
