zero point can be adjusted anywhere between 0 and 4 milliamps. Press ENTR when you have reached the desired zero point as measured by your test meter.

7.The display will now prompt you to adjust the Gain, or full-scale output of the current loop. Using the UP and DOWN buttons as in step 4, adjust the full- scale (usually 20ma) and press ENTR. This completes the current loop calibration. Press EXIT several times until you are back at the sample menu.
