When using direct wiring (PT Ratio = 1), voltages are transmitted in 0.1 V units, currents in 0.01 A units, and powers in
0.001 kW/kvar/kVA units. For wiring via PTs (PT Ratio > 1), voltages are transmitted in 1V units, currents in 0.01 A units,
and powers in 1 kW/kvar/kVA units.

The actual frequency range is 45.00 to 65.00 Hz

The output scale for signed (bi-directional) power factor is symmetrical with regard to ±1.000 and is linear from -0 to
-1.000, and from 1.000 to +0 (note that -1.000 ≡ +1.000). Negative power factor is output as [-1.000 minus measured
value], and non-negative power factor is output as [+1.000 minus measured value]. To define the entire range for power
factor from -0 to +0, the scales would be specified as -0/0. Because of the fact that negative zero may not be transmitted,
the value of -0.001 is used to specify the scale of -0, and both +0.001 and 0.000 are used to specify the scale of +0. To
define the range of -0 to 0, you must send -1/1 or -1/0 (considering the modulus of ×0.001).
5
When the 4LN3 or 3LN3 wiring mode is selected, the voltages will be line-to-neutral; for any other wiring mode, they will be
line-to-line voltages.
