OK...I need a way of remembering which is single-ended and which is differential.

Single-ended is when you have one wire and compare it to ground
Differential is when you have two wires and difference the two.

...now to remember this, only one of these has a "g" in it... sinGle-ended... and that's the one that references Ground.

ECTRON AMPLIFIERS (563H)
yes they are a pain to deal with.
To zero the bridge:
1. Short the input connection(pins B and C...pin layout can be found in schematic in back of manual).
2. Put gain to 1. Adjust RTO (referred-to-output) until output is zero.
3. Put gain at 1K. Adjust RTI (referred-to-input) until output is zero.
4. Put gain back to 1... if output is not zero, do steps 2 and 3 until it is.
