Micromanipulator 2 with a hand written 3 on it has a severly bent probe tip. Micromanipulator 2 is unable to move in the x-direction. Micromanipulator 3 has a missing knob in the y axis. Despite these problems, attempted to use micromanipulators 4 and 2 to probe diodes which had previously been tested on two other setups. The IV curve is not close to reading the correct diode curve. A short circuit can be read when both probes are on the same metal line, but on two different samples both of which had recently been tested on other setups, I was unable to see diode characteristics.
