What is typically used as the low-end fluid in a two-point calibration on a Rudolph refractometer? *

Ethanol

Distilled water or certified water

Olive oil

Acetone

Why is it important to calibrate both fluids at the same temperature? *

Because the software only works at one temperature

To avoid damaging the prism

Because temperature mismatch will invalidate calibration accuracy

To prevent printer errors

What is required to edit the calibration method on the instrument? *

A physical key

Customer support approval

A service password

Internet access

What common mistake can happen during the second fluid measurement? *

Using the same method twice

Not allowing enough time to warm up

Using a cracked prism
