Not familiar with the OGR meter.
But unless it's some odd-ball design, do the following. Place it in the Ohms/Continuity mode. It doesn't matter the range...but if there is a choice use the lowest range.
Note the reading with the meter probes not touching each other. If a numerical reading is indicated it should be some ginormous number in the millions or billions ... but more likely maybe just some dash symbols showing it's a huge number.
Then touch the two probes together simulating a short-circuit. The numerical reading should go to zero (0) or something near zero (i.e., less than 1 or 2 Ohms).
Then put red probe on the red Fixed 2 input, black probe on black Fixed 2 input. What does it read? I'm betting it's some very small number indicating a short circuit.
Oh. This is with NOTHING connected to the output of Fixed 2.
