I wouldn't worry about anything under 10V. My Sunpak 383 tests out virtually identically to what you're seeing with the 285HV and I've been using it on the DS for two years, on the K10D for six months. No problems at all.
What you're really looking to see is that it's not 200V... :-) G On Jun 1, 2007, at 11:07 AM, Ed Keeney wrote: > Godfrey, > > Thanks - I was able to borrow a tester from a colleague and from what > I can see (I'm an electrical novice) the flash was registering about > 8.2 with a high of about 8.6 on a recycle. > > A little higher than the 6 allowed -- do I go and spend the money on > the Wein Safe Sync? > > Thank you. > Ed > > On 6/1/07, Godfrey DiGiorgi <[EMAIL PROTECTED]> wrote: >> Ed, >> >> Just measure the 285HV trigger voltage to ensure safety.
