The meaning of "OPEN" displayed when a multimeter tests a diode
다이오드 테스트의 범위와 분해능은 고정되어 있습니다. 테스트 중 1mA를 출력합니다(1mA 전류 소스 출력 포함).
The multimeter beeps when the signal is at the {{0}}.3 to 0.8 V threshold (unless the siren is disabled). If the signal is greater than a certain voltage, "OPEN" is displayed on the front panel. Different multimeters have different voltage thresholds, such as Keysight's multimeter 3446XA is 5V, 34401A and 34411A are 1.2V.
