Remedy
Reset the average count setting value to within 4 to 500
times.
Reset the moving average count setting value to within
2 to 60 times.
Reset the time constant setting value to within 320 to
5000ms.
Check the voltage at the thermocouple input terminal.
Reset the offset/gain temperature setting value (Un\
G28 to Un\G43) of the channel number where an error
occurred.
Reset the data of the offset/gain setting (Offset
specification) (Un\G26) and offset/gain setting (Gain
specification) (Un\G27).
•Check the measurement range and reset the offset/
gain temperature setting value (Un\G28 to Un\G43)
within the range.
•Check wire disconnection or specify the channel for
conversion enable.
Reset the process alarm upper/lower limit value (Un\
G94 to Un\G125).
Reset the rate alarm warning detection period (Un\
G126 to Un\G133) to within 1 to 6000 times.
Check wiring status of the cold junction temperature
compensation resistor (RTD).
Reset the scaling range upper/lower limit value (Un\
G62 to Un\G77) or scaling width upper/lower limit value
(Un\G78 to Un\G93).
