I believe what you are trying to say is that the unit has 3 ranges. 0-4 inH2o, 0-20 inh2o, and 0-60 inh2o. These are the full scale values for the units 3 ranges.

Can you explain your question in a clearer way please?

What type of sensors are you calibrating or checking?

What is the expected range or output signal of these sensors?

What is the output signal or range of signals that you are actually measuring?

What is "inh20" and "inh2o"?

hi every one, well it is the least count selection ie 1. minimum LC is 1/4 ,2.LC is 1/20,3.LC is 1/60. which gives precise selection to get the accurate calibration .

to achieve your bench mark
