How can I to turn on the mA scale mode on the 773 ? 


The "Scale Mode" allows to output the amount of mA measured by the clamp via your 4mm banana jacks.
This is very helpful when for example you want to trend the mA of a loop with an external device and not wanting to break the loop to do this and so interfering with a process.

Going into scale mode:

  • Power up the 773 on as normal. 
  • When it is powered-up, press yellow button (shift) and then clamp-zero button ( mA scale). 
  • Now the 773 is in the scale mode so it sources the mA it measures through the clamp.
