Overview
2.1
Introduction
The USB TC-08 Single-Channel Terminal Board is an accessory for the Pico
Technology USB TC-08 8-Channel Thermocouple Data Logger. The screw terminals
allow wires to be attached to the data logger without soldering and enable the USB
TC-08 to measure voltages from 0 to + 5 V or 4-20 mA loop currents.
The terminal board is designed for use with the USB TC-08 and is not guaranteed to
work with other thermocouple data loggers.
