If you receive a Fail, prior to calling the factory try the following:
1) Reposition the gauge/case to another location (outside preferably)
2) Be sure that you are testing the gauge inside the carry case that was provided with the SDG.
The gauge and case are paired during production to determain the standardization.
3) Do not place the case on the back or near an automobile as well as any other large metal
objects and/or wires
4) Be sure that no foreign objects have adhered to the bottom of the gauge or on the steel plate
5) Shut off all cell phones within 10ft of the gauge
WARNING: THE STANDARDIZATION OF THE SDG 200 WILL ONLY WORK WITH THE PLATE
IT HAS BEEN ISSUED TO. IF YOU RECEIVE A FAIL RESULT, CHECK TO BE SURE THE SERIAL
NUMBERS LOCATED ON THE GAUGE AND THE STANDARDIZATION PLATE ARE THE SAME.
WARNING: THE STANDARDIZATION OF THE SDG 200 MAY GIVE A FALSE “FAIL” IF TEST IS
TAKEN TOO CLOSE TO METAL OBJECTS, POWER LINES OR OTHER ELECTRICAL DEVICES
THAT MAY BE TOO CLOSE TO THE GAUGE. TURN THE GAUGE OFF AND MOVE THE GAUGE
ATLEAST 10 FEET FROM THESE OBJECTS. IF AFTER THESE PRECAUTIONS ARE TAKEN
THE GAUGE STILL DISPLAYS A “FAIL” CONTACT YOUR DISTRIBUTOR.
Part 6: Standardization of the SDG
Part 7: Explanation of Gradation and Compaction Reports
All of the information needed to configure an SDG 200 to measure the density and moisture content of
a material is available on Compaction Test Reports (Proctor Test) and Particle Size Distribution Reports
(Gradation/Sieve Analysis) completed as outlined by ASTM D 422 and ASTM D 1557. In order to configure
the gauge to operate on materials that have high clay and silt contents, results from an Atterberg limits test
(ASTM D 4318) will be needed as well.
