电动土壤相对密度仪符合《土工试验规程》SL237-1999,《公路土工试验规程》JTJ051-93标准,本仪器适用于颗粒直径小于5mm的无凝聚土,且粒径2-5mm的试样质量不大于试样总质量的15%,以测定土的大密度和A小孔隙比,用于计算其相对密度。 仪器主要由机身、控制面板、传动机构、量筒、振动锤等零部件组成。
The electric soil relative density meter complies with the Geotechnical Test Regulations SL237-1999 and the JTJ051-93 standard for highway geotechnical test procedures. The instrument is suitable for non-condensed soils with particle diameters less than 5 mm, and the quality of samples with particle sizes of 2-5 mm is not It is greater than 15% of the total mass of the sample to determine the large density of soil and the small pore ratio of A, and is used to calculate the relative density. The instrument is mainly composed of the fuselage, control panel, transmission mechanism, measuring cylinder, vibrating hammer and other components.

电动土壤相对密度仪使用方法：
★插上电源，打开仪器右侧面电源开关。
★提起击杆，直至固定销插入击杆，保证击杆不会下落。这时拧松金属容器两边的锁紧螺钉，抽出金属容器，按规范要求，装入土样。将容器推入定位板中，并拧紧锁紧螺钉。然后一手扶住击杆一手拉出固定插销慢慢放下击杆。
★打开启动开关，仪器即进入待工作状态。
★转动定时器至所需时间位置，仪器即开始工作。
★试验结束，按《土工试验规程》（SL237--99）《相对密度试验》（SL237--010-99）方法进行测算。
★击实完成后，将锺头放下，拧松锁紧螺钉，将金属容器及护筒抽出。
★试验结束后，清扫仪器上剩土，关电源开关，取下电源插头，罩上防尘罩。
How to use the electric soil relative density meter:
★ Plug in the power and turn on the power switch on the right side of the instrument.
★ 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.
★ Turn on the start switch and the instrument will enter the standby state.
★ Turn the timer to the desired time position and the instrument will start working.
★ At the end of the test, the calculation is carried out according to the Geotechnical Test Procedure (SL237--99) "Relative Density Test" (SL237--010-99).
★After the compaction is completed, put the hoe down, loosen the locking screw, and pull out the metal container and the casing.
★After the test, clean the remaining soil on the instrument, turn off the power switch, remove the power plug, and cover the dust cover.
电动土壤相对密度仪安装调试方法：
★开箱后，按装箱单内容核对清单。
★将仪器放置于平整的水泥地面上，检查定位板是否松动，如松动，用扳手拧紧。提起锺杆，在试样筒中放入木垫块，放下锺杆。
★插上电源，按下仪器右侧面电源开关，将定时器定时在1--2分钟上，按下启动开关，仪器开始运
Installation and debugging method of electric soil relative density meter:
★ After unpacking, check the contents of the packing list.
★ Place the instrument on a flat concrete floor and check if the positioning plate is loose. If it is loose, tighten it with a wrench. Lift the mast, place the wooden block in the sample tube, and lower the mast.
★ Plug in the power, press the power switch on the right side of the instrument, and set the timer to 1--2 minutes. Press the start switch and the instrument starts to run.
