CAUTION Refers to hazards that could damage the instrument. NOTE Indicates tips, recommendations and important information. The notes simplify processes and contain additional information on particular operating steps. The following symbols may be found on the equipment described in this manual: This symbol on the unit indicates that high voltage may be present.
In some cases, where flash temperatures such as those generated by blasts and shock fronts are present, it Do not try to calibrate the Series 137A statically. The Series 137A is calibrated dynamically by PCB using may be necessary to thermally insulate the diaphragm to minimize signals generated by these effects.
