10001 Access code – character 1 (ASCII) 8 bits (LSB) 1.00 (2),(3)

(1) Read only.
(2) “8 bits (LSB)” indicates register least significant byte.
(3) The reading of an access code register doesn’t show the code character, but value 1, if the code is
active, or value 0 if the code is inactive. In writing, registers are used only for the temporary storing of
the characters sent by the user. Registers are not used to change the access code. It is not possible to
change the access code stored in the instrument through RS485. The instrument verifies the access
code correspondence after each written character.
Please note that the parameter address to be included in the command doesn’t match
the parameter number that appears in the menu of the instruments with keyboard or
that can be set through USB connection, as it can be observed in the table above.
Please refer to Table 5.A. for the values that can be assigned to parameters.
If the request involves the reading of at least one parameter that is not included in
Table 8.C, the instrument generates the following error message:
