처분 하려고 합니다, 구입한지 1주 됩니다, 르바란때 가져왔음 사용도 별로 하지 않았습니다,
스펙은 아래 참조 하시면 됩니다, 중국산이라서 정밀도는 별로 기대 하지
않는게 좋을거 같습니다, 테스터기 겸용이라서 직/교류 전압 전류 저항
콘덴셔 헬쯔 등 잡다한 기능들이 무지 많이 들어있습니다, 옵션으로
온도센서 도 구입 하였습니다, PC 연결 케이블및 프로그램은 재구입 해야
하는 관계로 구입 않했습니다, 박스는 없고 가방 및 본체 충전어댑터 및 온도 센서
확장 패키지 있습니다, 가격은 150만 루피아 예상하고있습니다,
필요하신분 쪽지 주세요
Features:
• Combination of a 4000 count auto-range True RMS DMM and
a handheld Digital Storage Oscilloscope at the size and the cost of a multimeter
• DMM functions include True RMS AC/DC voltage and current, resistance,
capacitance, frequency, duty cycle, dBm, diode and continuity tests
• Full auto set up for volt/div and time/div of DSO
• DSO Trigger mode: Auto/normal/single
• DSO Auto measure: Vpp, Vavg, Vrms, dBm
• DSO Cursor readout: dV, dt, 1/dt (frequency)
• Screen hold function
• Save and recall up to 100 waveform and data
• High contrast FSTN LCD with white LED backlight
