Additional Notes

Select the calibration phase

1.        Press or to select ‘PHAS’

This is found towards the end of the list of ‘P’ codes

Select low point calibration phase for the mA output to be calibrated (eg OP3)

2.        Press or to select ‘3.NA.L’

 

Calibrate the low point

3.        Press to select ‘vAL’

4.        Press or to adjust this value so that it reads the same value as shown on the ammeter. For example if the meter reads 2.06 then set the controller reading for 206. The decimal point is not displayed on the controller so that 202 represents 2.02.

5.        Press to confirm

 

 

Select high point calibration phase for the mA output to be calibrated (eg OP3)

6.        Press to go back to ‘PHAS’

7.        Press or to select ‘3.NA.H’

 

Set the output

8.        Press to select ‘vAL’

9.        Press or to adjust this value so that it reads the same value as shown on the ammeter. The value represents 18.00mA
