Accessing device data

With the exception of a few specially locked parameters, you can change all values after you have
inputted a code. Every change of parameters under legal control is entered in the "legal metrologi-
cal logbook" with a memory depth of 600 entries. When this logbook is full, the oldest value is not
overwritten, but an alarm message is outputted. You will not be able to change any other parame-
ters until the entries of this logbook have been deleted. To do this, you have to open the calibration
switch which is located on the main unit.

Data categories

The data can be divided into the following categories:
A - Values displayed: Values which are only displayed but cannot be changed as a rule.
B - User data: Data which can be changed after the user code has been entered; they are not en-
tered in the legal metrological logbook.
E - Data under legal control: Such data can only be changed after a calibration code has been
entered. They are entered in the legal metrological logbook.
N - Free parameters: Here changes can be made as standard without entering a code (but there
may be exceptions).
W - Factory settings: These can be changed with the service code and are entered in the legal
metrological logbook. These parameters are hidden in normal operation and will only be dis-
played after the service code has been entered. Using the Dialog 900 operating software, you
can see these parameters even without entering the code.

Codes

Accessing the data of the EC 900 is made possible via eight different codes. They stand for differ-
ent authorization levels.

C1
C2
C3

U1
U2
Changes of parameters are entered in the appropriate logbooks together with the relevant code. So
the changes are traceable. You enter a code in the same way as a parameter, but after inputting the
last digit you have to press " " instead of Enter in order to terminate your entry.
