The following conditions apply to the use of an unattended weighing system:
(a) Zero-balance condition. The unattended weighing system shall provide a means to indicate that the system is in a zero-load balance condition and ready for use. This indication shall be visible to the driver prior to the vehicle entering onto the load-receiving element. The unattended weighing system shall not complete a weighing operation if: (1) The scale is not at a zero-load balance at the start of the weighment (no load on the scale).(2) The indicating element is unable to automatically reset the zero-load balance when there is no load on the load-receiving element.(b) Position of vehicle. The unattended weighing system shall have sufficient gates, sensors or other automatic means to prohibit a weighment unless the entire vehicle rests on the load-receiving element. The unattended weighing system shall not record a weighment when it determines that the vehicle is not correctly positioned on the scale.(c) Indication and recording elements. The unattended weighing system shall be equipped with an onsite recording element, and either: 1) an audio and visual, or2) a visual indicating element that communicates the status of the weighing process to the operator (driver) of the vehicle. The recording element shall print the weighmaster certificate at the end of the weighment. For systems equipped with the capability to issue an electronic receipt, the customer may be given the option to receive the weighmaster certificate electronically, e.g., via cell phone, computer, etc.(d) Records security. The unattended weighing system shall be designed with a means to secure, maintain, and provide true copies of weighmaster certificates in either hard copy or electronic formats. All legally relevant data shall be stored and adequately protected against accidental or intentional changes.(e) Access for testing and inspection of records. The unattended weighing system shall be designed with a means to access all records, and with the capability to print records for the purpose of inspection. Contact information for the principal weighmaster shall be posted at the location to facilitate compliance with this requirement.(f) Tare capability. The unattended weighing system shall be designed with one or more of the following tare mechanisms: (1) Semi-automatic tare mechanism (load balanced automatically following a single operation initiated by the operator (driver));(2) Pre-set tare; tare that is stored in the system memory for recall at a later time and used for multiple weighments and is valid unless the actual tare of the vehicle and/or trailer(s) has been altered. The weighmaster certificate shall note the fact that a "stored tare" or "recalled tare" weight is being used.(3) Manual entry of tare by the driver into the system. The weighmaster certificate shall note the fact that "manual tare" weight is being used.(4) Predetermined tares; if a predetermined tare is used, the system shall be capable of receiving all information required under Article 3. of this chapter and indicate on the certificate that a predetermined tare was used.(g) Prohibited operations. The unattended weighing system shall not complete a weighing operation under the following conditions: (1) The unattended weighing system is designed to produce a printed ticket and one cannot be generated, e.g., if there is no paper in the printer.(2) The system loses communication or power, no weighing will be allowed until the system is reset; i.e., either manually or by other means returned to its normal operating condition.(3) The gross weight is above legal highway limits of 80,000 lb.(h) California Type Evaluation Program Certificate of Approval. California Type Evaluation Program (CTEP) or National Type Evaluation Program (NTEP) evaluated and approved components may be used as part of an unattended weighing system. The installation and use of unattended weighing systems or separable indicating elements and software controlling the metrological functions of the unattended weighing system shall be evaluated and approved by the CTEP.(i) Posting of weighmaster license. A copy of the current weighmaster license must be posted or continuously displayed and available at the location of the unattended weighing system. The system's unique identification number shall be listed on the license as the deputy weighmaster.Cal. Code Regs. Tit. 4, § 4496.2
