For the Sepam Modbus x1 and x10 zones, different registers are provided for clients with different capabilities.  For example, in the past some RTU's could read only integer values and did not have scaling functions to divide values by 10.

Sepam relays provide 2 different address zones for some measurements that give you 2 different scaling options.

1) The "x1" zone.  Here you get the actual value multiplied by 10.  So, if the Current Phase A is 91.8A on the front display, you will get a value of 918 (decimal) by reading the x1 Modbus register.  This gives you more precision in the value, but the RTU or Modbus client needs to divide the value by 10 to get the actual value.

2) The "x10" zone.  Here you get the value without any values after the decimal.  The value is rounded to the nearest whole number.  So, for example the actual Phase A Current is 75.6A.  In "x1 zone" you get 756.  For "x10 zone" you get 76.
