Source mode uses internal power to supply current from 0.000-24.000 mA into as much as 1200Ω (with
HART resistor disabled) until the end of battery life. The calibrator will indicate “HIGH Ω” if connected
improperly. The three-position EZ-Check switch provides instant zero and span calibration outputs. EZ-
Checks from 0-24 mA can be stored in the zero and span switch positions. The output is adjusted in 0.001
or 0.100 ma increments (0.01 or 1.00% in percent display units) with the EZ-Dial knob. Step the output
by pressing the EZ-Step button. Six different user-selected steps sizes are available. Hold the EZ-Step
button to activate hands-free auto step/ramp feature.

The Model 530 can simulate a 2-wire transmitter in the 4-20 mA process loop. The calibrator will indicate
“LOW SUPPLY” if improperly connected. The EZ-Check switch and EZ-Dial knob allow rapid and fine control
of loop current. The EZ-Step button and hands-free auto/ramp function allow a complete check of
calibration points.
