I Obtained values may be different from other measuring instruments Why is it so There are various possible causes Check the following first please 1 Check for wiring errors 2 Check for the settings phase wires primary voltage primary current and sensor type 3 On the split type current sensor check for the poor engagement or separation of fitting surfaces 4 Onthe split type current sensor check for pinching of foreign object between fitting surfaces A 5 Check for the short circuit on the secondary side of the current transformer CT 6 Current sensor connectable to the unit is the dedicated current sensor only Check that the proper current sensor is connected or not 7 Check that the measuring instrument used for comparison indicates a correct RMS value This unit indicates an RMS value If the measuring instrument used for comparison measures an average value instead of RMS value distortion caused by harmonic etc in the current of the circuit to be measured causes a significant difference of values 57 67 Q amp A about specifications li What does Allowable tolerance mean In terms of the amount of electricity it means a range of tolerances in reading values For example when the reading value is 10 kWh a tolerance is 0 2 kWh In terms of measured elements other than the amount of electricity it means tolerance for the rated input For a current when a rated current is set
