Meter Self-Diagnostics and Messages
The meter supports self- diagnosis, which can find some
common errors caused by meter, electrode, solution, or
operation. It deals with these errors differently according to
their severity.
There are two levels of severity: Severe system errors hinder
further use of the meter or make the meter unable to finish
necessary tasks. In this case, replacement or maintenance of
the meter is required.
Minor errors, which are prompts or warnings, are caused by
various reasons and can be corrected in several ways.
However, you must pay attention to these errors to ensure
measurement integrity and reliability. If you ignore these
error messages the operation can continue.
Severe errors
When severe errors occur in the meter, the meter will shut
down and display an error message similar to Figure 29. In
this case, the only operation that can be performed is to
turn off the meter.
