Scope

Main technical content: 6.2 Calibration Methods 6.2.1 Visual Inspection and Power-On Check To ensure that the power amplifier being calibrated can operate safely, reliably, and normally, a visual inspection and power-on check of the power amplifier should be conducted before formal calibration. a) The external structure of the power amplifier should be intact, with no damage or detachment of exposed parts. The casing, terminal buttons, etc. should not have mechanical damage that affects normal operation, and the buttons should not be stuck or have poor contact. b) The manufacturer, model, and serial number of the power amplifier being calibrated should be clearly marked. c) Accessories and connecting cables should be complete, and interface types, power supply voltage, frequency markings, etc. should be accurate and correct. d) During the power-on check, the output voltage and current should be displayed correctly, and all gain switching functions should function normally. Overheat protection, voltage short-circuit, current open-circuit alarm functions, pause control, status display, and high-power switching functions should all function properly. e) If the power amplifier uses external computer control, the control software should be able to communicate with the instrument and control its operation normally. f) The power amplifier should be equipped with dedicated grounding terminals. 6.2.2 Insulation Requirements 6.2.2.1 Insulation Resistance a) Short-circuit the output terminals and test the insulation resistance between the output terminals and the casing using a 500 V insulation resistance tester. b) Short-circuit all input terminals and test the insulation resistance between the power supply input terminals and the casing using a 1000 V insulation resistance tester. 6.2.2.2 AC Withstand Voltage Test Connect the high and low output terminals of the voltage tester to the power supply input terminals and the casing ground of the pow
