Yes, sorry.
I have no idea when it comes to electric. What do I set the multimeter dial to? I meant, do you have a pic of someone doing it? It’s easier for me just to watch to learn.
It's a straight-forward connection and measurement process.
1. Use an alligator clip to attach the postive test lead (red) to the tab on the sensor and another alligator clip to attach the negative test lead (black) to the body of the sensor. If you can't conveniently find a large enough clip, twist bare wire around the body and make sure it is very secure; then attach the lead to the bare wire.
2. Set the meter on Ohms (Resistance) setting. Most modern digital multimeters had automatic range selection so no need to set a range. If yours doesn't have autoranging, then set it on the 1000 Ohm range.
3. As Laitch instructed, place the sensor in the boiling water along with the thermometer, with the multimeter on. The reading should quickly start to drop.
4. When the multimeter reading has stabilized, then start to read both the multimeter and the thermometer at the same time as the water cools. The temperature should be dropping and the multimeter reading should be rising.
