resistance btwn pins 2-3 show 1.856 @ 2k ohm setting on my voltmeter. When I blow on the co pot it goes down to 1.6 and slowly returns to around 1.85
when I test resistance btwn pins 1-3 it initially jumps to some random number between 1 and .200 and then goes to 0 and sits there. No matter how I adjust the screw, it does the same, within 1 second of connecting to pins 1-3, voltmeter shows 0 ohms.
