Any lower and it may not be able to detect the transition from high to low and back and will read zero or be dodgy at best. There aren't any specs given for maximum but 5 to 10 V would be a normal requirement. | |
| Oct 9, 2016 at 8:27 | comment | added | Steve K | Do you think "80m Vrms" is a sloppy typo and should be "80 mV"? If so my signal would be far outside that range. Am I wrong? When you say "This would take the voltage down to 6 V p-p which should be fine." - what spec are you referring to that indicates 6vp-p is safe? | |
