num resistance thermometer has burned out
or A and B terminals have been short-cir-
cuited.

*When the temperature resistance thermometer is used, this message is displayed when the temperature has fallen below -99.9
°
C.
**E333 also appears if a PT platinum resistance thermometer is connected to E5EX thermocouple models.
Connection with G3PX Power Controller
Refer to the G3PX data sheet for the details of the G3PX Power Controller.
The following is possible by connecting the E5AX/E5BX to the G3PX:
Using the current output, more precise temperature control will be performed.
The life of the heater will be prolonged.
Connection Example:
