Thermocouple input failure discrimination law: According to the wiring diagram for proper wiring instrument powered thermocouple meter display instrument first indexing number of non-standard thermocouple, then display range of the instrument range, and then the next row of measuring instrument digital display set temperature, digital display on the instrument to measure the temperature. If the row on the instrument digital display non-standard thermocouple temperature heating element is not price, but displays "OVER", "0000" or "000" and other conditions, indicating that the instrument input parts failure, should make the following test: the failure of the instrument Remove thermocouple, for a normal run the same kind of thermocouple indexing number meter access by next energized, digital display temperature heating element on the original instrument failure, indicating a non-standard thermocouple wires open thermoelectric even distribution, replacement of the same type of thermocouple. In accordance with the correct wiring diagram instrument, if the instrument is powered rear, behind the digital display on the instrument has a negative phenomenon, indicating that access to the meter Thermocouple "+" and "-" pick the wrong caused. As long as you can look back exchange. Non-standard thermocouple supply nonstandard thermocouple, the lowest price since the instrument measuring the force provided by the Shanghai Automation Instrumentation Co. measured. Shanghai Automation Instrumentation Co., force measurement (www.licesh.com) (http://www.licesh.com) strong, credible, in Shanghai Zhabei District, flow meters and other industries has accumulated a large number of loyal customers.
