I am trying out your EL040 current monitor kit on the bench.The problem is current readings are much higher than expected.( showing 65 amps when clamped to a 1 amp circuit)The clamps supplied are PDI CA-300 and not the TA011 as stated in the manual. The clamps have been set to 1mA although either setting makes no difference. Is this a known problem? do i have to alter any settings?
