8. Error Codes
When the instrument detects an
error, the standard display changes
to include the error symbol and error
number alternating with the regular standard
display, total heat quantity. There are seven
possible causes of error, and they can appear in
combination with each other, depending on the
situation.
The occurring error is shown on the LCD in the
format “Err xx”. The “xx” stands for the error no.,
shown in hexadecimal form.
For example, Err 08 -> scanning coil fault
