The Cell-PDA module allows an external differential voltage to be measured and recorded simultaneously with the primary signal, without the need for a peripheral port. This brings extra functionality to instruments such as the dModules in the Ivium-n-Stat and the pocketSTAT2/Vertex.One/Vertex.C.
The module connects between the instrument and the cell cable. Screw contacts then allow the connection of wires between the cell and the + and – terminals. The voltage is automatically recorded on the analog input 1 channel.
