4.1 Oscilloscope Operation (OSC)

The AT312G features a built-in 12MHz bandwidth oscilloscope with a 50MSa/s sampling rate. It supports automatic, conventional, and single waveform scanning modes.

• Entering OSC Mode: From the voltage section of the multimeter mode, press and hold the "AUTO" button for 2 seconds to enter the oscilloscope (OSC) mode.
• One-Button Auto Oscilloscope: In OSC mode, briefly press the "AUTO" button to automatically adjust the waveform display for optimal viewінж.
• Карэкцыя часовай базы: Under the main menu of the oscilloscope, press the F1 key (TIME) to enter the time base adjustment sub-menu.
• Рэгуляванне дыяпазону: In the main menu of the oscilloscope mode, press the F2 key (VOLT) to enter the range adjustment sub-menu.
• Захоўванне дадзеных: Press "SAVE" to temporarily hold the current waveform data. Press "SAVE" again and hold for 2 seconds to enter the database, then press F4 (SAVE) to permanently save the current data. The device can store up to 10 waveforms.

Figure 4.1: The device can measure waveform amplitude up to 200V/grid with a maximum measurement of 1600Vpp.

4.2 Функцыі мультыметра

The AT312G functions as a 6,000 counts digital multimeter, offering a wide range of measurement capabilities.

• Пераменнага токуtage і частата: Connect the test leads to the appropriate terminals and the circuit. The device can measure AC Voltage from 0 ~ 750V and Frequency from 1 ~ 20MHz. Use the SEL button to cycle through different measurement parameters like frequency and duty cycle.
• Вымярэнне супраціву: Rotate the knob to the Resistance (Ω) setting. Connect the test leads across the component to measure resistance from 0 ~ 60MΩ.
• Вымярэнне дыёдаў: Select the Diode (⟘) setting. The device has an open circuit voltage of 2.8V for diode testing.
• Вымярэнне ёмістасці: Switch to the Capacitance (Cx) setting. The device can measure capacitance from 10nF ~ 100mF.
• DC Voltage: 0 ~ 1000 В
• Пастаянны/пераменны ток: 0 ~ 10A
• Бесперапыннасць: Judgement resistance 50Ω.

6. Тэхнічнае абслугоўванне

6.1 Ачыстка

Для чысткі прылады выкарыстоўвайце мяккую, damp тканінай. Не выкарыстоўвайце абразіўныя ачышчальнікі або растваральнікі, бо яны могуць пашкодзіцьasing or display. Ensure the device is powered off and disconnected from any power source before cleaning.

6.2 Сыход за акумулятарам

The AT312G uses a Lithium Ion battery. To prolong battery life:

• Пазбягайце частай поўнай разрадкі акумулятара.
• Захоўвайце прыладу ў прахалодным, сухім месцы, калі яна не выкарыстоўваецца працяглы час.
• Перыядычна зараджайце прыладу, калі яна захоўвалася працяглы час, каб пазбегнуць глыбокага разраду.

6.3 Захоўванне

When not in use, store the AT312G in its protective carrying case to prevent damage from dust, moisture, and physical impact. Avoid storing in extreme temperatures.
