Erratic readings • Verify that the wires are terminated properly. • Check that the +12 to 30 Vdc input is clean. In areas of high RF interference, shielded cable may be necessary to stabilize signal. Inaccurate readings • If you suspect that the current sensor is not reading within the accuracy specifications, please contact the factory for assistance. CURRENT CONVERSION FORMULA To convert the current sensor output signal to a current reading. Current reading = mA output/20 mA x Amp Span. For example: For a reading of 4 mA with a 0-250 Amp span: Current reading = (4 mA/20 mA) x 250 A = 0 Amp. (0/16) X 250 = 0 NOTE: 4mA = 0 Amps 20 mA = 250 Amps Automation and Control Solutions Honeywell International Inc.
