Penetrometer Electric H-1240.4F Humbolt |
|
Introduction |
|
For complete test procedure ( s ), refer to the following specifications: ASTM D5, D217, D937, D1168, D1321, D1403, D1831, and AASHTO T49. |
|
Installation |
|
1 Level the instrument carefully by means of the leveling screws on the base, sighting the spirit level from above, in order to obtain accurate alignment. After the instrument has been leveled, avoid shifting its location. |
|
2 Position the height of the supporting casting by turning the knurled travel nut on the main support post and then tighten the black knob. |
|
3 If additional weights are used, these should be taken from the side post and set on the end of the plunger ( opposite end of the needle chuck ). |
|
4 Insert penetrating needle or cone into chuck and tighten the chuck screw. |
|
Operation |
|
1 Holding the plunger with one hand, squeeze the lever on the front of the support casting with the other to allow raising the plunger & needle to clear the sample. Flip the toggle switch on the front panel to the up position and pre-select the specified time of penetration by turning the knobs on the timer bezel. |
|
2 To conduct a test set the needle, cone or micro-cone on the sample surface. When ready to begin, press the red pushbutton on the front panel to release the plunger for the pre-selected amount time. The timer- controlled electromagnet will immediately release the plunger and after the preselected time interval will re-grip it to stop the test. |
|
3 Measure the travel of the plunger assembly by lowering the dial indicator rod to contact the plunger and observing the dial reading. |
|
4 To reset for the next test, the front panel toggle switch must first be flipped to the down position, then the above sequence can be repeated. |
|
CAUTION : Keep hands, clothing and other objects away from moving parts when the machine is in operation. |
