Steps to move the magnet current from 74.51 A to 74 A

1. Select the option "Up to 74.51 A at 0.5 A/m" from the "Presets" field.
   
   
   
2. Press the "To Set" button and wait until the "Output current (A)" increases up to 74.51 A. It will take about 5 mins, and once the output current reaches 74.51 A, it will be automatically switched back to the "Hold".
   
   
   
3. Press the toggle button next to the "Main Switch Heater" status indicator. Once you press it, then it will show a similar screen as shown below.
   
   
   Once this process is completed, then the "PD Readings" will indicate ON (see the screenshot below).
   
   
   
4. Select the option "Down to 74 A at 0.5 A/m" from the Presets.
   
   
   
5. Press "To Set".
