12. MAINTENANCE AND GUARANTEE...................21 1. Application The ND10 meter is a digital programmable panel meter destined for the measurement of the 3- phase, 4-wire power network parameters in balanced and unbalanced systems. It is also capable of displaying measured quantities and their simultaneous digital transmission. The meter is also capable of controlling and optimization of the power electronic devices, systems, and industrial installations. -

ND10 METER OF NETWORK PARAMETERS Fig. 2. Meter dimensions. 5. Meter Description 5.1. Current inputs All current inputs are galvanically isolated (internal current transformers). The meter is suited to operate together with external measuring current transformers. Displayed values of currents as well as their derivative values are automatically calculated using set ratio value of the external transformer. -

ND10 meter register map ND10 meter has data contained in 16-bit and 32-bit registers. Process variables and meter parameters are placed in the address area of registers in a way depended on the variable value type. Bits in 16-bit registers are numbered from the youngest to the oldest (b0-b15). 32-bit registers include numbers of float type in IEEE-754 standard. - Page 16 ND10 METER OF NETWORK PARAMETERS MULTIFUNCTION METER Issue 1.0...
