How to assemble chain adapter portable hardness tester.
When you get the equipment carton.
Firstly, check the material and item as per packing list that was put inside the package carton.
Read the manual and assembly the component. It's easy for you if with
have mechanical knowledge background and following the manual, step by
steps
1-Fix the test head onto adapter frame using the screw bolt in the provision.
2-fix the third supporting bar( foot) total three foot that touch
against the cylinder. The three foot also working as supporting point
Which keep space between the test ball and cylinder surface.
3- hang the chain onto the adapter frame refer to the O.D of cylinder

So, agian remind you that read the manual is very important for using the chain adapter PB3000-A3 first time
Main Component make known
1. Indenter
The indenter is composed of indenter body, indenter ball and indenter holder. The ram body is the hydraulic system which transfers the test force onto the part. Make sure the indenter is not extended more than 10mm before loading test force. If the indenter is extended more than 10mm, it will not create a valid indentation because the test force is not able to reach 3000kg. Don’t use the pump handle until the indenter is in contact with the part. The instrument uses the carbide ball for testing. The advantage of the carbide ball is it is hard, durable, and highly accuracy.
2. Gauge
The gauge is an
indicator of the test force and lets the operators see the test force as it
increases and decreases. The gauge does not control the test force and
while it is representative of the load it does not fully capture the dynamic of
the test.
Make sure to
protect the gauge.
3.Pump Lever
The function of the pump handle is to make the hydraulic system produce a test force. Moving back and forth of the pump Lever forces a small piston in the hydraulic system to press oil into the cylinder, and the pressure transfers to the indenter. The indenter will respond to this process by moving and increasing the test force on specimen.
4-Calibration Valve
The calibration valve is the auto control pressure switch
of the hydraulic system. Before leaving the factory, the calibration valve is
calibrated accurately to 3000kg,
with a tolerance of less than 1%. When the pressure in the cylinder reaches 3000kg, the calibration valve
will instantly open releasing the pressure. Once pressure drops below 3000kg, the calibration valve
closes.
Do not remove the calibration
screw or the tester will lose accuracy
