• locate the container for the probe that has broken (we will need to maintain a list of which probe is in which position)
• disconnect power to the appropriate bridge enclosure
• open the empty probe container
• loosen the end of the probe support
• carefully (linked two-hand method) pull the broken probe out
• carefully put the broken probe in the container end cap
• carefully screw the container cover onto the end cap
• carefully remove the container cover from the new probe
• carefully put the new probe in the end of the probe support and ensure that it is connected and rotated to have the sensor vertical
• tighten the end of the probe support
• open the bridge enclosure
• open the specific bridge
• referring to the sheets below for the specific new probe (SF1–9), set the DIP switches
• close the bridge
• close the bridge enclosure
• power on the bridge enclosure enclosure

We only have 7 probes for the 4 positions for the entire experiment, so we want to be very careful to avoid accidental breakage!!
