APPLICATION NOTES

1. If the instrument does not answer within the “max answering time”, it is necessary to repeat the

query. If the instrument does not answer after 2 or 3 consecutive queries, it must be considered

as not connected, faulty or having a different address. The same consideration is valid in case of

CRC errors or incomplete frames.

2. By entering the programming mode (by pressing the “S” key) the communication is interrupted.

Any data received during the programming mode are ignored.

3. EEPROM read and write commands must be carried out to manage “static” variables. Use them

only during the instrument set-up and not during the normal measuring mode in order to avoid to

extend the answer time and to limit the writing in EEPROM (max 100.000).

4. Control lines are not managed.
