there is a pulse measurement this charger is capable of. but for the life of me I can't figure out how it's performed. the manual is as bad as a futaba manual. basically says here it is in the menu. done. LOL so substance. have you ever seen it? the manuals says you have to plug the servo into the top spot and that's about it. there's no "start" button to begin the test. maybe mine needs a firmware update. I don't know. but all I do know, I can't get it to do anything. the regular servo tests work.
this is literally all the manual says about the pulse measurement test.
Select SYSTEM MENU→Extra Function→Pulse Test to enter the pulse test interface, only J2 port supports the input
