I installed a 80-300v (Standard +) meter, but it is only showing the VOLTAGE and HERTZ. VOLTAGE shows 248.0V, AMP 0.00A, the WATTAGE is 1.0W, 59.9 HZ, 0.00 KWH, and 0.00PF.
Any ideas why the AMP, WATTAGE, KWH and PF are not reading?
Are you sure the load wire goes through the current sensor? Would you pleaes show us your connection by image? If it is hard to show the complete wiring by images, you may try to draw a simple diagram. We hope to check where the wire goes to.
