5. Setup
Follow these steps to set up your PeakTech 4095 Multimeter:
- Unpacking: Carefully remove the multimeter and all accessories from the packaging. Retain the packaging for future storage or transport.
- Power Connection: Locate the power input on the rear panel. Ensure the voltage selector switch (110V/240V) matches your local power supply. Connect the provided power cable to the multimeter and then to a suitable AC outlet.
- Initial Power On: Press the power button on the front panel. The TFT display should illuminate, and the device will perform a self-test.
- Connecting Test Leads: Insert the red test lead into the 'HI' input terminal and the black test lead into the 'LO' input terminal for most voltage, resistance, and frequency measurements. For current measurements, refer to the specific input terminals (e.g., 10A, mA/µA).
- Interface Connection (Optional):
- USB: Connect the USB cable from the multimeter's rear USB port to your computer.
- RS-232: Connect the RS-232 cable from the multimeter's rear RS-232 port to your computer's serial port (or a USB-to-serial adapter).
- LAN: Connect an Ethernet cable from the multimeter's LAN port to your network router or switch.
Install the provided software from the CD-ROM on your computer to enable remote control and data logging via these interfaces.
6. Operating Instructions
This section outlines the basic operation and various measurement functions of the PeakTech 4095.
6.1 Basic Measurements
- Voltage (DCV/ACV): Select the desired voltage function (DCV or ACV) using the function buttons. Connect the test leads in parallel to the circuit under test. The display will show the measured voltage.
- Current (DCA/ACA): Select the desired current function (DCA or ACA). Ensure the test leads are connected to the appropriate current input terminals (e.g., 10A, mA/µA). Connect the multimeter in series with the circuit.
- Resistance (Ohm): Select the Ohm function. Connect the test leads across the component to measure its resistance. Ensure the circuit is de-energized before measuring resistance.
- Capacitance: Select the Capacitance function. Connect the test leads across the capacitor. Ensure the capacitor is discharged before measurement.
- Frequency: Select the Frequency function. Connect the test leads to the signal source.
- Temperature: Connect the provided temperature sensor or a compatible thermocouple/RTD to the appropriate input terminals. Select the Temperature function and choose the correct sensor type (e.g., Type K, PT100).
6.2 Special Functions
- Range Selection: Use the 'Range' button to switch between auto-ranging and manual ranging. In manual mode, press 'Range' repeatedly to cycle through available ranges.
- MIN/MAX/AVG: Press the 'Math' button and navigate to MIN/MAX/AVG to display the minimum, maximum, or average values recorded during a measurement session.
- Relative Measurement: Use the 'Math' button to activate the relative measurement function, which displays the difference between the current reading and a stored reference value.
- Data Logging: Press the 'Record' button to start/stop data logging. Configure logging parameters (interval, internal/external memory) via the 'Record' menu. Data can be saved to internal memory or an external USB stick.
- Graphical Display Modes: Use the 'Graph' and 'Dual' buttons to switch between numerical display, trend graphs, histograms, and dual measurement displays.
