Site density tester use method

1

Filling the sand cartridge with sand, the height of the sand in the cylinder is not more than the distance from the top of the cylinder

15mm

, weighing the weight of the sand in the cylinder, it is difficult to

1g(m)

This weight should be maintained for each calibration and subsequent tests.

2

Open the switch, let the sand flow out, and make the volume of the discharged sand equal to the burrow of the test hole in the construction site.

(

Or equal to the volume of the calibration tank

)

Then, turn off the switch, and when the weighing cylinder is no longer flowing down, close the switch and carefully remove the sanding cylinder.

(

Do not touch the sand filling cylinder during the entire grit

)

Until the sand in the sand storage tank is no longer flowing down, close the switch and remove the tank sand tube, and weigh the remaining sand in the cylinder to the exact
