Manwal tal-Istruzzjonijiet tat-Termometru SD Logger b'Erba' Kanali Extech SDL200

1. Introduzzjoni

The Extech SDL200 is a versatile four-channel thermometer and data logger designed for precise temperature measurement and recording. It supports six types of thermocouples (J, K, E, T, R, S) and two channels for RTD (Pt100Ohm) probes, allowing for a wide range of applications. This device can display individual channel readings (T1, T2, T3, T4) or differential readings (T1-T2). It features an offset adjustment for relative measurements and can store up to 99 readings manually, with an extensive capacity of 20 million readings via a 2GB SD memory card. All recorded data is time-stamped and saved in an Excel-compatible format for easy transfer and analysis on a PC. The SDL200 also includes user-programmable sampling rates, Min/Max recording, Data Hold, Auto Power Off, and a built-in PC interface.
