Therefore, 0% = 4mA, 25% = 8mA, 50% = 12mA, 75% = 16mA, & 100% = 20mA.

6.If adjustments are needed, press zero. The display now shows:

zero: x.xxx 04.000 +y.yyy mA

x.xxx represents the default zero value (low scale) and y.yyy is the adjustment made to 4mA for the analog output signal. The adjustment can either be positive or negative shown by + or - respectively. The top line will alternate between zero: x.xxx and UP/DN TO ADJUST. This is the zero adjusted value to calibrate the analog output to 4mA.

7.Press or to increase or decrease the output until the meter reads 4mA or the current zero reference matches the field equipment. Press ent to collect the new point.

8.Press span. The display shows:

span: x.xxx

20.0+y.yyy mA

4 - 4

x.xxx represents the default span value (full scale) and y.yyy is the adjustment made to 20mA for the analog output signal. The adjustment can either be positive or negative shown by + or - respectively. The top line will alternate between span: x.xxx and UP/DN TO ADJUST. This is the span adjusted value to calibrate the analog output to 20mA.

9.Press or to increase or decrease the output until the meter reads 20mA or the current span reference matches the field equipment. Press ent to collect the new point.

10.Steps 5 - 9 are required only once. They may be repeated as often as necessary while in calibration, but only the most recent point will be saved on completion of calibration.

11.To permanently store the results of the calibration press ent, and the unit will prompt Enter to accept Calibration. Simply press ent again to save the calibration. Press esc to abort the calibration.
