- Page 6 Operating Instructions & Parts Manual Seating Your Diamond: Caution: To ensure accuracy, mount the indentor by sliding it in the holder as far as possible and then securing the indentor by tightening the set screw finger‐tight only. Place HRC test block on the small round anvil and begin by turning the handwheel clockwise until the block just touches the diamond. At this point, continue rotating the handwheel until the large needle goes around approx. 3 revolutions. Let the machine sit idle for a few seconds and then loosen the set screw. Wait a few more seconds and then tighten the set screw back up. This will allow the diamond to be “seated” in the shank. Take the load off by turning the handwheel counter‐clockwise and you can begin following instructions below. Rotate the weight adjustment knob until the required weight scale is aligned with the alignment mark on the frame of the machine. 1. Prepare the test specimen properly. Be sure that the top and bottom surfaces of the specimen are clean and free of any grease, oil dirt, etc and free of any burrs or debris. 2. For small specimens (under 3" maximum length or diameter) use the small round anvil. Use the large anvil for larger specimens. Use the V‐shaped anvil for round or curved specimens. Warning! Do not test any specimen that cannot be safely and properly positioned on and supported by the tester anvil Operation: Determine the proper indentor, scale and weight for the material hardness to be tested (see Figure 3). Mount the required indentor in the indentor holder using the set screw (Fig. 6, Ref. Nos. 27 and 28) on the side of the holder. Test Procedure Test procedure consists of a preload of the specimen using the force of the elevation screw and a test load using the weights and lever arm assembly. Be sure that the weight reset handle is in rest (“unload”) position. 1. Mount specimen on required anvil. Rotate the elevation screw threaded collar clockwise slowly until the specimen contacts the indentor. Be sure to position specimen so the indentor contacts clean, untested material. 2. Preload the specimen by rotating the leadscrew collar slowly until the large needle on the dial indicator rotates two to three (2‐3) revolutions. Stop rotation of handwheel when the large needle is within 3 hash marks of vertical(TDC) Caution: As the large needle is properly rotated 2‐3 revolutions, the small needle rotates counterclockwise 90 to vertical at the red dot. If the large needle overshoots vertical by more than 5 hash marks, the test is invalid and must be repeated from step 1. 3.

Remove the top cover off the 900‐345A. Adjusting the set screw that controls the Indicator needle starting point: Carefully hold the set screw with a thin blade regular screwdriver. While holding this screw steady, carefully loosen the set screw hex nut. Making a very slight turn Counter‐Clockwise on the set screw, you will see the large needle on the dial begin to turn counter‐clockwise on the dial. Continue turning until there is no more contact between the set screw and needle adjuster. At that point turn the set screw until it just touches the adjuster and snug the hex nut back in place while holding the set screw to prevent it from turning. Take a minimum of 3 tests on your test block to make sure the machine is reading correctly. If readings are low, you will need to back off on the set screw a little more. The opposite if readings are high. Page 7...

Page 23: Taking A Test
Operating Instructions & Parts Manual TAKING A TEST: Assuming the indicator has been set up correctly and the Auto Zero is turned on, you can begin taking a test as you normally would with your hardness tester. A) Make sure you have the correct penetrator installed and the weight selection set for your hardness scale. Reference the Weight Load Indentor Chart 1) Be sure that your anvil is clean of oil, dust, rust, etc. 2) Place a good quality calibration test block on the anvil and begin rotating the test block up until you just make contact with the penetrator. 3) Continue rotating up and immediately take not of the Analog bar on the left side of the indicator. This will rise as the block continues into the penetrator. The indicator will soon “Beep” alerting you that its almost at the top. Once the pre‐load is set the indicator will show either 2.80mm or 3.20mm (depending upon the scale set) and immediately change over to 100.0HRC. The analog bar will be solid right up to the Circle. See picture below: Pre-load Indicator 4) Once you see the display as shown above you must now apply the major load on the hardness tester. You will now see the values on the display change in a descending order. 5) Once the value on the display is stable (should be between 5‐8 seconds) you must now Unload the machine and you can take your reading directly off the indicator display. IMPORTANT! Your first test should always be discarded. Begin testing for average on the second test. ASTM suggests that you take 5 tests and obtain your average. That average is the value to be used as the true hardness reading. Page 23... - Page 24 Operating Instructions & Parts Manual CALIBRATION: The 9500 series indicators have a built‐in calibration feature which should only be used for fine adjustments. If the obtained results on your calibration blocks are well outside of tolerance, you should adjust and repair the base machine before you adjust the indicator. 1) Press the Menu/Enter button. Scroll down to System and highlight it. Press the Menu/Enter button again and you must scroll down to Correction. 2) Press the menu/Enter button and you will see three choices: a) Off b) On c) Enter If you don’t want to change calibration then leave it in the off position and return to the main test screen. If you highlight ON, this will activate the Auto‐Calibration feature which will allow the indicator to automatically correct the measured value when the “Lock” feature is on. If you highlight Enter, this will allow you to set the calibration by manually entering in the value shown on the test block. Example: If the value shown on your test block is HRC 25.8 then you would enter that value while in the enter screen. Now take a test on that same test block as normal. Once the result has been obtained Press the Menu/Enter button and then choose Save and then save the calibration. If you choose Exit then the calibration will not be saved. Maintenance: The 9500 series indicators are highly sensitive and accurate instruments and should be treated as such. These should remain in a temperature controlled environment with the least amount of shock or vibration as possible. Cleaning: Use soft damp cloth only. Do not use harsh chemicals as this will deteriorate the finish of the indicator. Technical Support and Repair: Contact Phase II at (201) 962‐7373 Page 24...
