Indicated battery and other operational tests must be performed prior to each use to assure that the instrument is functioning properly. If applicable, failure to conduct periodic performance tests in accordance with ANSI N323-1978 (R1983) Radiation Protection Instrumentation Test and Calibration, paragraphs 4.6 and 5.4, and to keep records thereof in accordance with paragraph 4.5 of the same standard, could result in erroneous readings or potential danger.
Section 2 Installation 2.1 Installation CAUTION Ensure all power is removed prior to installing the 948A- 40 or 948A-50 Remote Alarm, Alarm/Meter. Installation of the 948A-50 Remote Alarm/Meter consists of finding a suitable location for mounting, such as a wall or post, and providing an electrical interface.
Section 3 Operation 3.1 Operation Since the operation and theory for the 948A-40 is identical to the 948A-50 with the exception that the 948A-40 has no meter, only the 948A-50 will be discussed. Once installation has been completed, operation of the VICTOREEN 948A-50 Remote Alarm/Meter is automatic and does not require operator attention.
Section 4 Maintenance, Calibration, and Troubleshooting 4.1 Maintenance The 948A-40 Remote Alarm and 948A-50 Remote Alarm/Meter require no routine maintenance other than periodic calibration for the 948A-50.
