The security code is set to “HP_
E1412
” for C-size when the multimeter is
shipped from the factory. The security code is stored in non-volatile memory,
and does not change when power has been off or after a remote interface reset.

can contain up to 12 alphanumeric characters.
The first character must be a letter. The remaining characters can be letters or
numbers or an underscore. You do not have to use all 12 characters but the first
character must be a letter.
•
If you forget or lose the active security code, you can disable the security
feature by adding a jumper inside the multimeter (see Chapter 5 in the Service
