The hardest part is finding a low voltage ac source. Having said this, I struggled to get very accurate measurements when I tried this myself with a multimeter. Remember to put the multimeter on the AC setting.
If you are tempted to put 6.3v AC in the secondary, remember that it will translate to quite a high voltage on the primary. |
Thanks Gabe, I will give that a go. I have a 6v ac supply which should work ok, albeit with caution.
