General DescriptionThe rH-45AUTO(superficial) Modular Rockwell hardness testers are accurateadvanced instruments distinguished by their friendly operation, high accuracyrepeatability, reliability, and versatility They are used foraariety of metals in diffens They are arhines built withecise force sensors, force monitoring electronics systems, and depth measuremenstemsThe RH-45AUTO are made up of a main unit and a set of frames Each framespecialized for holding a certain test specimen shape or size By switching frames on themain unit, you can easilypecialized testersThe rH-45AUTO can directly measure and produce 15N, 30N, 45N, 15T, 301and 45T readings, and can convert to HV and HB scales The hardness tester hasBluetooth and USB capabilities for sending test results to a Bluetooth printer or PC∧cAUT|ONThe rh-4sautotomated testers
Do not touch any movable parts of the testersuch as the indenter, when the tester is operating or injury may occur2 Before beginning a test, ensure the indenter is placed in the position sleeve Otherwisethe displacement sensor will be damaged The tester has a safety feature to detect if thedenter is missing If so, the presshead will automatically move backwards, and"NoIndenter"will FLASH on the displayINDENTER3 The presshead and indenter cannot move forward more than 25mm Any attemptadvance the presshead forward more than 25mm or retract the pressback backward beforethe startingill turn off thetaining frare tester on the column stand if the test specimen is too small

Testing principle and procedurePress the o key to power on the tester Then, place the test specimen between theanvil and indenter Then, press the key once to move the indenter towards the testpecimen as the indenter is moving, you can press the stop key to stop movementPress the< key again to resume movementWhen the indenter pushes against the test specimen, the poamp the test specimen Then, the indenter's tip will penetrate into the test specimenng an indentationThe indenterand apply a force on the test specimen Whenhes the preliminary test force Fo, the inderspecified dwell time The tester then measures the indentation depth on the test specimenAfter waiting, the indenter will move again and further deepening the indentation
When the applied force reaches the total test force F, the indenter stops moving and waitsspecified dwAfter waiting, the indenter moves away from the test specimen, and decreases theorce it applies on the test specimen when the applied force decreases back to thepreliminary test force FO, the indeving and waits for a specified dwell timeThe tester then measures the larger indentation depth on theThe LCd displays the hardness reading Finally, you can print the readings to a Bi cimenth indentation depths to calculate the hardness of the speci5 Pre-Treatment of the test piecePreparation of the test piece surface prior to testing will help insure accuracya The test should be carried out on a clean surface that is free from oxide scaleforeign matter, and especially lubricantsPreparation should be carried out in such a way that minimizes alteration of theace hardness (for example, heat or cold-working)C The thickness of the test piece should be no less than 0
08 in(2mmd The test piece should have a smooth even surface The test surface should bepolished so that a metallic luster appears Measurement errors could result fromthe roughness of the test surface The roughness(Ra) of the surface must belimited6 Basic Operationsowering on the devicekey to power on the tester The lcd will displayn window whicwill show the previous test readingMAX 62AVE 627Hv7649005627N45
