1 Introduction
The Watlow temperature control box (generally referred to as the Watlow bow) is a temperature control device with the capability of monitoring up to 4 devices at a time. These devices can be a mixture of local PT100 instruments and heating pads. Data transfer from the box to GDSLab is via RS232 serial communication using a PC comm port.
A PT100 will always be set as device one, heat pads following this will have to be connected to the respective 2, 3, 4 thermocouple slots on the rear of the Watlow box.
