If D.C. voltage is present, reconnect the negative wire of the supply and insert a milliamp meter
between the positive wires. The loop should provide a signal between 4 and 20 MA. If no current is
present or the current exceeds 20MA consult the level instrument supplier.
If D.C. voltage is not present check the user supplied power supply or if using the Myriad supply
measure across terminals 24VDC and AIC. If no 24VDC is present consult factory. If 24VDC is
present check field wiring between the Myriad and the field device and recheck ‘SCALE’ functions to
ensure correct setup.
