Procedure
A. Actuating
Load the driver with a power load and probe suited for the type of concrete being examined. Place the driver firmly on the actuating template and fire. The locating template is then used to locate the probes at the corners of a fixed triangle. Normally, three measurements are required for consistent and statistically reliable results.

B. Measuring
The electronic measuring device is menu driven and programmed for selection according to the following parameters.

• Aggregate hardness
• Light weight, normal, or HP concrete
• American or Metric units

The three individual tests are automatically averaged and displayed on the LCD in accordance with ASTM procedure. This data together with time and date of the test are stored in the memory for subsequent uploading to a PC. An extractor is supplied to facilitate probe removal after the test.

The Standard Windsor Probe™ System includes a depth gauge and “Strength Chart” for determining the concrete strength.

This is an economical alternative for many concrete test environments.
