11RECORD KEEPINGEach organization/company that employs PAS V units should assign a staff member tobe responsible for care and maintenance. A log should be established to record thechecking, calibration and maintenance activities on each unit. Testers using the unitsshould be required to report any problems with the units to the PAS V staff member whoshould record the problems in the log. If a unit is dropped or is damaged in some otherway this should be entered in the log so that the information can be forwarded to themanufacturer along with the unit for repair. The log will record the life history of the unitsand should be carefully maintained since it may be subpoenaed if the use of the PAS Vis challenged.To ensure that there is a record that these sensitivity checks have been conducted on amonthly basis, it is necessary to establish a log with a record for each of the PAS Vunits employed by the Company or Department. An example of such a record is shownbelow.PAS V LOGBOOKDate Unit #ReturnedProblemReported Checked By Action TakenDateReturned toManufacturerDateReturned toFieldThe example shown provides a means for recording any reports from Testers ofproblems with the PAS V units or any unusual occurrences such as dropping theflashlight onto the pavement. The log also provides a brief description of the actiontaken to overcome the problem or to examine the unit for damage as a result of atester's report. The log will note instances in which the PAS V has been returned to themanufacturer for service and when it was received and checked upon its return. Thelog should also contain a notation recording each month's sensitivity check and theoutcome of that check and also a calibration adjustment if such an adjustment wasnecessary.In addition to monthly sensitivity checks, PAS V units should be checked if they havereceived an unusual stress such as being dropped on the pavement. If a PAS V unithas been sent to the manufacturer and returned following repair, a check should bemade to ensure that the calibration was not affected by the handling during shipping.Also, perform periodic functional checks with known sources of alcohol to be certain allfunctions (e.g., pump) are performing.
