1) thermocouple inputs to remove the heat from the instrument, and the instrument with any wire thermocouple input terminal short-circuit. When power, instrument on row digital display values around room temperature, indicating internal wiring open circuit thermocouple, thermocouple should be replaced with the type. If it is said, indicating instruments in the course of transport, instrument input is damaged, replacement of the instrument.
2) remove instrument thermocouple failure, swapped runs next to normal access to the same index number on the meter's thermocouple, power, the instrumentation on the digital display at the fault heating element temperature shows thermocouple wires open circuit, replace the same type of thermocouple.
3) thermoelectric couple from failing down on the instrumentation, measured with a multimeter on ohms (r) *1,
Both ends of the rod to measure thermocouples the two tables with a multimeter, if the resistance value is displayed on the multimeter shows internal connection open thermocouple, replace the same type of thermocouple. Or have a certain resistance, indicating instrument input terminals have a problem, you should replace the instrument.
4) instrument wiring diagram wiring is correct, if instrument power, the row digital display on the meter negative phenomena description access instrument thermocouple "+" and "-" caused by a wrong. As long as the change again.
