They say a person with one clock knows what time it is. But a person with many clocks does not. Seems the same is true for tools that measure voltage.
When you have 3 volt meters, and they give 3 different readings on the same cell, how do you know which one is right? The one that cost the most money?
I'm in between batches of cells at the moment, and I'm taking a break to improve my methods and equipment. I've got 6 tools now that need to measure voltage accurately, and they don't all agree with each other. So the good news is that the Opus, iMax clone, and my Innova multimeter all agree within 1/100V. So I'm starting with the assumption that they are accurate. Especially because I don't know if the Opus can be calibrated.
Two other tools are also multimeters; cheaper than the Innova, and the voltage can be adjusted by a potentiometer on the circuit board.
Synchronized!
I'm also collecting some voltage displays so I don't have to keep using the multimeters for everything. Very important to get the ones with an adjustment pot on the back, as well as a separate power input if you want to read voltages of less than 3V. I've learned this the hard way...
Synched!
So my last tool that needs calibrating is one I haven't figured out yet. Maybe you guys can help?
I just bought a genuine SkyRC iMax B6 minifrom Amazon. The new model with the USB port. Its about 1/4Volt low compared to the other meters, and as a consequence is charging the cells about 1/4Volt too high. I can kind of live with this for now by using the LiIon setting, but it sure would be nice to have all my tools agree with each other. I've tried searching Google and You Tube but those methods work with the clones and not with the genuine iMax's.
