Introduction
In designing the MULTICAL® 601 we have attached great importance to flexibility via programmable functions and plug-in modules (see chapter 10) in both the calculator top as well as in the base unit to ensure optimal use in a large number of applications. In addition, the construction ensures that already installed MULTICAL® 601 meters can be updated via the PC program METERTOOL.
This technical description is prepared to give managers, meter electricians, consulting engineers and distributors the possibility of utilizing all functions available in the MULTICAL® 601. Furthermore, the description is made for laboratories for the testing and verification process.
During the preparation of this technical description we have drawn attention to the functional differences in changing from MULTICAL® type 66-CDE into MULTICAL® 601 to secure a safe product conversion for existing users.
At each relevant paragraph that refers to this product conversion there will be comments marked as follows: 66-CDE ⇒ MC 601

MULTICAL® 601 is a thermal energy meter with many applications. In addition to being a precise and reliable heat meter for battery or mains operation, MULTICAL® 601 is also used for:
Cooling measurement in water-based systems
Bifunctional heat/cooling measurements in separate registers
Leak surveillance of hot and cold-water installations
Power and flow limiter with valve control · Data logger
Data communication
Energy measurement in open systems
