help identify missing components agilent u1242b

[Syzeryuino]

Hello i was given by someone a u1242b from someone and says that its not accurate. after inspecting it a few components are missing mainly the one in these photos.
i wasnt able to get a clear picture from the pictures on the internet. can anyone with similar multimeter help me?

its the resistor and the diode. though i wont expect anything from the diode cause its so small!
