Sync voltage on Smith Victor
Does anyone know how to test sync voltage on Monolights? I have a set of
Smith Victor 110i monolights, and I can't find the voltage anywhere. Thanks blah |

Counted the number of hits I got that confirmed the synch voltage. They all of them said...4.3 volts. for your unit in particular. If I didn't know the answer, or thought the answer was wrong, do you think I would post it and put your expensive equipment at risk? Lg |

Lg Not an accusation, I'm not seeing anything on Google for voltage on a Smith Victor 110i. thanks Find a STORAGE oscilloscope, preferably non-sampling, say 50 to 100 Megahertz, with 20megohm probes. Attach one probe to middle of synchronizer plug on STROBE, and the other probe on the outside of the male plug, which is not going to fire the unit, because the impedence is too high and to the strobe componenets, it looks like an open circuit. Set the sweep rate at whatever, but the vertical at 3 volts/division. Now, take a piece of wire and touch the center conductor of the plug to the outer plug wall. FLASH And...you have a *trace* on the scope showing you what the firing sync voltage of your unit is. A DVM is not good enough for this, because it is a sampling device, not a *real time* device. And an analog meter wouldn't know what to do with such a short pulse. Now I've found the values for Smith Victor flash heads to vary between 4.3 volts, 4.4 volts, and 5 volts. Nothing larger, nothing smaller. This is definitely well within the safety limits of any camera with a sync socket. HTH Lg |

Lg Not an accusation, I'm not seeing anything on Google for voltage on a Smith Victor 110i. thanks Nevermind all that ****. What I realized just now is the above is not correct. You just measure the voltage differential when the flash is ready to fire, between the male plug center conductor and the outer jacket, with ANY kind of **** voltmeter. Whatever that voltage is, is the sync voltage. Thank You. Lg |
