from anywhere in the configuration menus, when no button is pressed during 
the set time interval of 10 minutes.
Code 51  *MODE   The manual impedance check (on demand) can be setup for operation in the 
maintenance mode. (Through the closed front cover).
Code 52  *PASS   Passcodes can be set on any or all of the access levels, to restrict access to 
the instrument configuration.
Code 53  *Err.4.1  Error message configuration. Two different types of failure mode can be set.
 Hard fail gives a steady FAIL flag in the display, A Fail signal is transmitted on 
the outputs when enabled in code 32.

a good example of where a SOFT fail is useful. A warning that the regular 
maintenance is due, should not be used to shut down the whole measurement.
