Page 6: Leeb Measuring Method
Leeb Measuring Method History The Leeb measuring method was first brought into measurement technology in 1978. It is defined as the quotient of an impact body’s rebound velocity over its impact velocity, multiplied by 1000. Harder materials produce a higher rebound velocity than softer materials. -
Page 7: Notation Of Leeb's Hardness
Notation of Leeb’s Hardness • When measuring the hardness of a sample material using the traditional static hardness testing method, a change of applied pressure will result in a change in the hardness reading. This will also happen during a Leeb’s Hardness test when you change the impact device. -
Page 8: Supporting A Test Sample
Supporting a Test Sample When using impact devices D, DC or D+15 (Impact energy=9ft/lbs), please refer to the following support requirements: • For test samples weighing over 11 lbs. (5 kg), no support is required. • Samples having a cantilever or thin shell shape and weighing between 4.4 to 11 lbs. -

Page 12: Printing Stored Data
Connect the included power supply in the back end of the printer. Using the supplied data port connections, connect the single port end into the side of the PHT-2500. Connect the 9-pin female end to the included dual male end adapter. Connect the 25- pin adapter male end to the 25-pin female end data port of the mini-printer. -
Page 13: Measuring Procedure
Use standard test block to check your hardness tester prior to a hardness test. (1) Loading Press down the loading tube to lock the impact body. (Fig 9) Figure 9: Loading the PHT-2500 (2) Placement Place the support ring on the surface to be measured. The distance between two test points should not be less than 0.1 in (3mm) (Fig 10). -
Page 14: Arithmatic Mean Of Hardness Of Current Measurements
Arithmatic Mean of Hardness of Current Measurements Usually the arithmatic mean of measurements should be the average of 5 to 33 or more sets of measured data. Shutting off the PHT-2500 PHT-2500. Press the Red power button to terminate use of the... -
Page 15: Additional Features
If the LDC screen continuously blinks, this may suggest a low battery voltage. Simply turn off the power and change the batteries. Maintenance and Repair Avoid placing the PHT-2500 near locations where it can be exposed to shock, heavy dust, dampness, strong magnetic fields and oil stains. Impact Device •... - Page 16 Revised operational instructions for the DL impact probe If you purchased your PHT-2500 hardness tester prior to ordering your optional DL impact probe, you must follow the instructions below before performing any tests. Without these instructions, the outcome of hardness values will display higher than the actual hardness value of the sample test piece.
