MASTER/REPEATER OPTION (MSTSLV code):
Specific programme for use of the indicator as a universal weight repeater or as a multi-scale repeater (MASTER) in combination with DFW/DGT/MCW.

Functioning Modes:
Multi-scale repeater (MASTER)
function which allows to repeat up to 32 independent scales, with the possibility of managing their functions, or displaying and printing the sum of the weighs of all the scales.

UNIVERSAL weight repeater
function which allows to repeat the weight of any scales, through the configuration of the input string.

Integrated Web Server:
The integrated WEB SERVER allows complete diagnostics, calibration and remote configuration of the weight transmitter from ethernet network.

Only for PROFINET, ETHERNET IP and MODBUS TCP models.
