The LCD didn't behave like I thought it would. I used an HP33120A Function Generator. Set to sine wave. 3.0V p/p.
I have a BNC connector on the function generator with a set of test clips on the other end. It doesn't matter which lead I use. One lead will light a segment, sometimes two segments. Sometimes the word "oz". Sometimes the word "lb". And the 4th position has 1/2 sized characters. Sometimes the segment stays on for seconds after I lift the lead. Sometimes it goes off right away. I didn't write anything down
The pins are oriented 17 pins on the bottom and 11 pins on the top (orientation determined by the text that pops up and the decimal points)
Pins 5-8, 16, and 17 on the bottom row don't do anything when individually probed
Pins 1, 4, 9, and 11 on the top row don't do anything when individually probed <-- this kind of mimics the orientation of the common on other LCD displays that I found datasheets for but using the pins as a common doesn't affect the way the bottom row of pins responds.
