Thanks first of all for this chance.

I am working in laboratory as lab technician and i am using the T.O. machine in testing materials.

My question is as the load is controled with a load valve, but what does the numbers indicate ie 0 to 50 

 

The test machine is as shown below.

 TINIUS OLSEN UTM 2000KN CAPACITY MODEL AC8500 S/N 106750

 

Answer

The machine you've referenced is a 400,000lbf capacity Deluxe Super L hydraulic testing machine with extra height and a low base. The machine was made in 1970 and was sold to a customer in Australia. I assume you refer to the graduations behind the loading capstan - these numbers have no significance other than as a guide to open the capstan to, to approach a similar loading rate for each test. As the hydraulic oil heats up, the loading rate will change and will need to be adjusted, so these graduations were simply there as a helpful guide for operators.
