1
Depending on the selected depth of yearly and monthly logs in the programmable data logger these display readings
can include empty readings.
2
The average is volume based.
3
Only the date of min/max is displayed in format 20xx.xx.xx. By serial reading the time (hh.mm) is included too.
4
Inputs A and B are currently updated in the display of MULTICAL® 403, thus the display of the connected water or
electricity meter will be in accordance with the display of MULTICAL® 403 without delay.
5
The unit of this reading is fixed at kW. The reading updates at the same speed as the integration interval, which is
determined by the L-code.
6
These are fixed readings under module info.
7
These readings depend on the module and are thus not fixed readings. The order of the readings can vary, therefore,
the index number is set at ”xx”.
8
Temperature cutoff has been introduced from software revision 14540201 (B1), this display will not be available in
earlier versions.
9
In software revisions prior to 14540201 (B1), the segment test is found on index number 2-25-25.
6.2.1 Module readings
”TECH loop” includes a number of module readings which depend on the module. These readings are described in
the respective technical descriptions for the modules. Simple modules, however, only include the primary reading
”Type-Config number” (index number 2-101-00). If the meter is not fitted with a module ”Type-Config number” is
displayed as ”0000000”.
Note: The module readings can be empty due to delay or interrupted communication between meter and module.
Heart beat indication shows that both meter and display are active
