5.4.3.0 Run the Test
5.4.3.1.0 Turn On Hydraulic Power
Use the control panel to apply hydraulic power.
1. If the Interlock indicator is on, click Reset to release system interlocks.
If the interlock remains on, use the message logs to identify and correct the cause of the interlock.
2. Click Low Power.
This action sets the hydraulic power unit to high pressure and the hydraulic service manifold to low pressure.
3. Click High Power.
This action sets the hydraulic service manifold to high pressure.
5.4.3.2.0 Enter DCPD Initial Crack Values
This activity applies a load to the specimen and measures the initial voltage across the specimen crack for
DC Potential Drop (DCPD) tests.
1. Click Enter Initial Crack on the Main menu.
2. Specify the following parameters, and then click OK. The parameters determine the load level that is
applied and how the voltage is measured.
