Actual measurement value (input value)
With the scaling function, the current value measured by the LR8513 Wireless Clamp
Logger can be measured while it is converted to a power value of single-phase 2-line
wiring.
By entering a V ×
λ
value (V: Voltage,
λ
: Power factor) in
[Ratio]
and setting
[W]
for
[Units]
under
[Scaling]
, the power value of single-phase 2-line wiring can be
displayed.
Power value W = Scaling conversion ratio × Current value = V ×
λ
× Current value
Setting example: When the voltage is 100 V and the power factor is 0.8, the power
value of single-phase 2-line wiring is to be measured.
