P - Change PIN

This command changes the PIN (Personal Identification Number) that
protects the calibration data. The instrument is shipped with the PIN
000. If the PIN is lost, the default (000) may be restored by fitting the
‘default’ link and switching off and then on.

Note:

Restoring the defaults restores ALL of the factory settings including the
communication parameters.

Command:

P, PIN, New PIN

Where:

PIN is the existing 3-digit code (000 to 999) and New
PIN is the replacement PIN.

Reply:

None

Result:

PIN is replaced by New PIN
