Disassembly Procedures for the M3015A Measurement Server Extension
Repairing the Instrument 233
Removing the Extension Bottom Cover
To remove the Extension bottom cover, do the following:
Step 1 Position the Extension on the dual link bar with the measurement connector
hardware facing upwards and the arm of the dual link bar towards you. There are
four long mounting pins threaded into the Extension in each of the four corners
under the cover. Locate the heads of the two long mounting pins on the side away
from you.
Step 2 Use tweezers to prise the pins gently out enough to be removed by hand.
Step 3 Remove the two pins and set them aside for refitting.
NOTE Do not lose these long mounting pins since the Extension will not function unless they are in
place.
Step 4 Using your hands, gently pry the bottom cover away from the Extension at the link
bar end first. The bottom cover is press-latched at the link bar end. Remove it gently
making sure not to bang or touch the inside of the Extension.
NOTE If you accidentally try to remove the wrong side of the bottom cover, you will notice that it is
attached to the inside of the Extension with a ribbon connector and that the dual link bar
prevents you from removing it completely. Do not try to forcibly remove the wrong side of
the M3015A cover; you cannot access replaceable parts from this side.
