Purpose
A nuclear density gauge must be entered in the system by your MetaField Administrator for it to be available for a Density Test. A new gauge requires 5 standardization counts to be entered.

Depending on the gauge selected, MetaField will automatically adjust according to the Method the gauge was calibrated (Standard Count or Radioactive Decay) |

Warning |

Standardization Date will not default to a date. Pay careful attention when entering this date. That date you enter must be >= the last standardization date you entered, so it is important you enter your standardization data in the order they were done. It is recommended that firms make it a practice of entering their standardization data as soon as possible (ideally on the job site after you run the standardization) and no later than the day the gauge was standardized. |
Info |
---|
The standardization is based on the previous four (4) standardization counts along with the current values for that day. |
...
To determine if the moisture count passes, the absolute value of the following is evaluated: (New Moisture - Average Moisture) / Average Moisture <= gauge's Rx Moisture Limit / 100 To determine if the density (1 and 2) count passes, the absolute value of the following is evaluated: (New Density - Average Density) / Average Density) <= gauge's Rx Density Limit / 100 |
Standard Count (Troxler 3450 Gauges)
The following screen will appear if a gauge is calibrated to record 2 density readings. This is mainly used to support Troxler 3450 gauges.
- Supply the both Density and Moisture values and Moisture value from your gauge
- Click the Perform Test button
- Review the standardization results
- Save the standardization results if valid or re-enter the standardization data if data was entered in error

- Supply the Standardization Date
- Supply the Density and Moisture Standard Counts Measured from the gauge
- Click thePerform Testbuttonthe Perform Test button
- Review the standardization results
- Save the standardization results of valid or re-enter if data entered produced a standardization fail.

Once your counts are saved, Gauge Standardization is complete. At this point, you will be given 3 options:
Field | Description |
---|---|
Enter Another Count | Select this option when the gauge standardization failed, but there is an exception to be considered (e.g. humidity). |
Standardize Another Gauge | Select this option to enter standardization counts for a different gauge. |
Perform A Soil Density Test | Select this option to visit the project selection screen and begin the Soil Density Testing process. |
