1 # Measuring TCS for sample holder in more detail than 25-06-2012
3 # Pressure = 3.12e-7 mbar
12 # Vi (V) Ie (uA) Is(uA)
16 #0.30 10.5 0.09 # This is a big increase, so I decided to go back to 0.20 and step up in 0.01 V increments
17 #0.20 10.5 0.10 # This is wierd, should be ~ 0.01
20 # The electrometer measuring Is has a different offset.
21 # At the start of the experiment, I used the zero check to make sure the offset was 0.
22 # Now, the zero check shows an offset of 0.14 uA (at 10:03; it has been increasing since I stopped recording)
24 # Start 10:03, recording offset vs time
26 # Time (min) Offset (uA)
28 1 0.19 # Disconnected electrometer lead... no effect
32 # Scale on electrometer is 10e-6 A , multiplier is x 0.01
