Instructions

1

Plug in the power and turn on the power switch on the right side of the instrument.

2

Lift the stroker until the fixed pin is inserted into the stroker to ensure that the stroker does not fall. At this time, loosen the locking screws on both sides of the metal container, pull out the metal container, and load the soil sample according to the specifications. Push the container into the positioning plate and tighten the locking screw. Then hold the strut with one hand and pull out the fixed pin slowly to lower the strut.

3

When the start switch is turned on, the instrument enters the standby state.

4

Turn the timer to the desired time position and the instrument will start working.

5

At the end of the test, in accordance with the Geotechnical Test Procedures (

) Method to measure.

6

After the compaction is completed, put the hoe down, loosen the locking screw, and pull out the metal container and the casing.

7

After the test, clean the remaining soil on the instrument, turn off the power switch, remove the power plug, and cover the dust cover.
