Table 70: Register 35 - WAGO 750-495/040-00 Series Manual

84 Process Image
The transformation ratio is set either with WAGO-I/O-CHECK or in registers
39 ... 42. In the process, the divisor for the current transformer ratio (D-CTR) is
set in the registers. Corresponding to the examples above, these would be:
• 750-495/040-000 (1A):
• 750-495/040-001 (5A):
This yields the following calculation of the measured values for the current-
dependent variables:
