Sample Units Check

The DQM Check for Sample Units verifies that sample results are reported with appropriate unit types. For this check to work properly, RT_UNIT.UNIT_TYPE of each unit used in the lab results must be populated with the appropriate values.

Check

Check name is EarthSoft.DQM.VerifySampleUnits = Verify Sample Units.

Parameters

This check uses the REPORTABLE_RESULT, RESULT_TYPE_CODE, and TEST_BATCH_TYPE parameters from Global Parameters.

The check has two other parameters and they are:

•unit_type – Defaults to “cpw, cpv”.

•checkDefaultUnits – Defaults to “N”.

Notes:

•The default value is used if there is no record in RT_DQM_CHECK_PARAM for an input parameter.

•The default value is used if the PARAM_VALUE is NULL for this parameter in RT_DQM_CHECK_PARAM.

Rules

There are two rules:

1.INVALID SAMPLE UNIT TYPE = Qualify results if RT_UNIT.UNIT_TYPE of a lab result unit is not among the ones defined in the unit_type parameter.

2.MISSING SAMPLE UNIT TYPE = Qualify results if RT_UNIT.UNIT_TYPE of a lab result unit is missing.

Errors

In the Errors tab of the DQM Event Review Form, this error may be listed:

•"One of the required rules for this check is not present in the RT_DQM_RULE table."
