5. Configuração

5.1 Conexão de Energia

1. Before connecting the power cord, verify that the voltage selector switch on the rear panel is set to the correct mains voltage para a sua região (110V ou 220V).
2. Connect the supplied power cord to the power input socket on the rear panel of the multimeter.
3. Conecte a outra extremidade do cabo de alimentação a uma tomada elétrica CA aterrada.
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 Configuração Inicial

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. Instruções de operação

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 Medidas Básicas

• Volumetage (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.
• Resistência (Ω): 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.
• Teste de continuidade: Select the resistance function and look for the continuity symbol. An audible tone indicates continuity.
• Teste de Diodo: Select the diode test function (often combined with resistance). Connect the test leads to the diode to measure its forward voltage gota.
• Frequency (Freq): Connect the signal source to the HI and LO terminals. Press the 'Freq' button to measure the frequency of an AC signal.
• Temperatura (Temperatura): 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.

6.3 Funções Avançadas

• Funções matemáticas: The 'Math' button provides access to various mathematical operations on measurement data, such as MIN/MAX, AVG, dB, dBm.
• Utility Menu: The 'Utility' button allows access to system settings, calibration, display options, and interface configurations.
• Exibição dupla: The 'Dual' button enables simultaneous display of two different measurement parameters or a primary measurement with a secondary parameter (e.g., AC voltage and frequency).

7. Conectividade

The PeakTech 4095 offers multiple interfaces for data transfer and remote control.

• Interface USB: Connect the multimeter to a PC using the USB device port on the rear panel. This allows for data transfer and remote control via software. The front panel USB host port is for connecting USB storage devices for data logging.
• Interface LAN: Connect the multimeter to a network using an Ethernet cable. This enables remote control and data access over a local area network.
