D, DC or D+15, the test surface should be polished until its roughness Ra is no more than 2 m. PHASE II SRG-2000 handheld surface roughness tester or any other suitable instrument may be used to measure the surface roughness of the sample material.
mass metal object. The sample must be completely stationary and without any gaps between the two parts. ⚫ Curved surface: The best testing surface of sample is flat. When the curvature radius R of the surface to be tested is smaller than 30mm (D, DC, D+15,C, E and DL type of impact device) and smaller than 50mm (G type of impact device), the small support ring or the shaped support rings should be chosen.

4.3 Placement Press the impact device supporting ring firmly on the surface of the sample, the impact direction should be vertical to the testing surface. 4.4 Testing ⚫ Press the release button on the upside of the impact device to test. The sample, the impact device as well as the operator are all required to be stable.
4.5 Read Measured Value After each impact operation, the LCD will display the current measured value, impact times plus one, a beep will alert you if the measured value is not within the valid range. When reaching the presetting impact times, the beep will alsonotify you.
The instrument can be turned off by pressing the key while it is working. The tool has a special memory that retains all of its settings even when the power is off. 5.2 Material Setting Press key to change the material to the one you want to preset. Hardness scale defaults to HL automatically after material presetting changed.
Note : ⚫ This displays the valid hardness scale for the present selected impact device and material. It would not display the hardness scale which is not valid. ⚫ Please select material first, then select hardness scale. ⚫ Presetting hardness scale recovers to HL automatically after presetting material is changed.
1) Press the key to activate the data logging function. The memory icon will appear. It will display the current file name, the test parameter of the group data and the mean value of the group. If there is no data in the memory, it will display: <E04>, which means no memory data, and then return back.
When the voltage of the battery gets too low, the display will show <E00>, then power off automatically. 5.11 Battery Replacement The PHT-1800 uses standard AA batteries. After several hours of usage, battery symbol on the screen will begin to show less dark tabs which is shown as .
6.2 Instrument Maintenance Program ⚫ When testing in the Rockwell C hardness scale your error amount should not exceed 2 Rockwell C points. Changing the spherical test tip or impact body should be considered. ⚫ Warranty will be VOID if unit has been dismantled by someone other than an authorized repair person 6.3 Fault Analysis &...
