Set the FUNCTION SWITCH to REJUV. Press the REJUV button. The external DVM should read greater than 350Vdc.
Reads about 4.7V FAIL
Are you giving it some time after you set the function to rejuv? In that position, it charges a large capacitor - if you push immediately, the cap may not have charged fully.
Most important, the discharge curve for the cap once you push the rejuv button is quite steep - use a DVM pre-set to the highest range, as an autoranging meter takes time to "range up" to the highest range needed to read the voltage. By the time the autoranging gets there, the cap is discharged.
Me thinks your CR70 is fine, just gotta setup things correctly.
