| What was your first multimeter or voltmeter? |

My first voltmeter was an incandescent lightbulb. Seriously. I used it for half a decade until I could afford something more conventional. At school, when we needed to measure voltage to 0.1%, we used a NiFe cell, a 1m piece of resistance wire and and ruler, and a 1.0186V standard cell. Seriously. See my .sig and change "span" to "voltmeter :) |

Also, we had a lot of 4.5V batteries in Germany in those days of my childhood and the tongue pretty much measured them as well. |

One of the EEs in my Ham Radio Club seriously built a Tube transmitter many years ago without a multimeter - estimating the voltage by the kick off the back of his hand FFS :scared: |

But then, presuming those batteries were for bicycle lights, that's probably because I do my best to forget those dreadful lights. |
