STATUS LED to blink RED (slowly). However, a
power factor lower than 0.5 could cause the LED
to blink this way, even if the unit is installed
properly.
• It does not matter which side of the CT faces
towards the load.
• Check actual current with Amp clamp. Expected
power is: kW = Volts x Amps x 1.732 x PF / 1000;
kW = Horsepower x 0.746 (PF is usually 0.7 to
0.95 depending on the nature of the load)
• Compare this to the kW. If current is below 7%
of full scale maximum for the CT, use a smaller
CT or wrap each wire through the CT multiple

side of the conductor. The power meter cannot
communicate without voltage.
Status LED blinks red.
• If the LED blinks quickly (i.e., about 5 blinks in
two seconds) the CT used is too small. Replace
with a larger CT.
• If the LED blinks slowly (i.e., about 1 blink
in two seconds) the CT is not installed on the
correct conductor, or the power factor is less
than 0.5. The meter can accurately measure
these low PFs, but few loads operate normally at
such a low power factor.
