Counters
For every element two set of counters are available (Partial counters and Total counters); the partial
counters can be cleared by the user level, while the Total counter reset can be achieved with pass-
word (Session Level 1).
Every partial counter is reset to zero when ten thousand count is passed.
All partial counters can be cleared by means a single command; for this purpose the Reset partial
counters command must be issued (
Commands \ Reset submenu).
