If you lost it you will need to buy new one and solder it in.

content: The PCB you show looks like it has been soldered before... No by you I suppose?Are you sure the meter is still working?I am sorry for my bluntness, but based on your shown experience you do not seem to have that much experience in electronics...Are you sure you are capable to make this repair and would it not be wiser to put this one with a correct description on ebay and buy yourself a working new one (calibrated and within spec?)
