Next-LCD

The Next-LCD is a completely autonomous, all-purpose measuring device. All measured characteristics are displayed as digits and graphs on-screen. The closed software environment of the device eliminates inaccurate readings. The device has two Lab-Bus digital bus ports to which the pressure sensors, microphones or power sensors can be connected. All this makes Next-LCD an all-purpose and completely cascadable tool. When a user purchases, for example, this set for measuring sound pressure, in the future they can supplement it with our microphone for measuring AFC or with our power sensor for measuring current and voltage. Simultaneous work with two signal sources is possible. The built-in sound signal generator of different waveforms (sine, white noise, pink noise) works in background mode alongside the process of measuring. The Next-LCD can be connected to a PC for controlling the device and transmitting data via USB, for example, when it is necessary to display the measurement results on a big screen. The device can be fitted with the built-in Wi-Fi module for connecting to Wireless networks which allow transmitting measurement data for long distances via the Internet in real time mode.

Software characteristics

• The SPL mode for measuring sound pressure peak values with possibility of displaying the spectrum and waveform of the measured signals. Simultaneous work with two signal sources. Distortion (clip) detector
• The AVG mode for measuring the weighted time-average value of a sound pressure. Simultaneous work with two signal sources
• The RTA mode for measuring AFC with possibility of displaying the spectrum and waveform of the measured signals. Displaying with breaking the spectrum into octaves. Distortion (clip) detector
• The PWR mode for measuring alternating/direct current and voltage, power, frequency of the signal, non-linear distortion (clip) coefficient. Simultaneous work with two signal sources
• GEN mode. Background stereo generator of test signals: sine, pink noise and white noise
• The CON mode for connecting with PC. Allows performing customization and transmission of the digitized data for detailed analysis in Measuring Center for Windows

Ergonomics

The Next-LCD device is performed as a monoblock that has graphic display with back light, 8 control buttons, USB port for connecting to a PC and for charging the device, two Lab-Bus ports for connecting sensors, two RCA type outputs of the sound signal generator, feed switch and three-coloured LED for indicating status and extent of battery charge. The device can be supplied with the built-in Wi-Fi module for connecting and managing via the local network. The case of the device is made of shockproof plastic material.
