4. Press the power button on the front panel to turn on the device. The TFT display will illuminate, and the device will perform a self-test.

5.2 การกำหนดค่าเริ่มต้น

Upon first power-on or after a factory reset, you may need to configure basic settings such as language, date, and time. Navigate through the 'Utility' menu using the front panel buttons to adjust these settings.

6. คู่มือการใช้งาน

The PeakTech 4095 offers various measurement functions accessible via the front panel buttons. Always ensure test leads are connected to the correct input terminals for the desired measurement type.

6.1 การวัดพื้นฐาน

• เล่มที่tage (V= / V~): Connect test leads to the HI and LO input terminals. Press the 'V=' button for DC voltage or 'V~' (often combined with V= or selected via a sub-menu) for AC voltage. The device supports True RMS measurements up to 100 kHz.
• Current (A= / A~): For current measurements, connect the test leads in series with the circuit. Use the 10A RMS input for high currents or mA/µA for lower currents. Select 'A=' for DC current or 'A~' for AC current.
• ความต้านทาน (โอห์ม): Connect test leads to the HI and LO input terminals. Press the 'Ω' button. The device features a fast response time for resistance and continuity tests.
• การทดสอบความต่อเนื่อง: Select the resistance function and look for the continuity symbol. An audible tone indicates continuity.
• การทดสอบไดโอด: Select the diode test function (often combined with resistance). Connect the test leads to the diode to measure its forward voltagอีลดลง
• Frequency (Freq): Connect the signal source to the HI and LO terminals. Press the 'Freq' button to measure the frequency of an AC signal.
• อุณหภูมิ(อุณหภูมิ): Connect the Type K thermocouple wire sensor to the dedicated temperature input terminals (if available, or via adapter to HI/LO). Press the 'Temp' button. The device can measure temperatures up to 1000 °C (1372 °C maximum specified).

6.2 Graphical Display and Data Logging

The 4-inch TFT display allows for graphical representation of measurements, such as voltage trends over time. Use the 'Graph' button to switch to graphical mode. The 'Record' button initiates data logging, storing measurement points to internal memory or an external USB drive connected to the front panel port. The device can store up to 1 million measurement points.
