11-3-1. Connection cable
To connect the other sensor systems, follow the general pattern of the terminal connections as
listed below:
11 & 12 Temperature compensation resistor input
(Pt100, Pt1000, 3k Ω PTC, 5.1k Ω PTC, 8.55k Ω NTC, 350 Ω PTC, 6.8k Ω PTC, 10k Ω PTC)
13 Input no. 2 (normally the reference element)
14 Liquid earth (solution ground) connection
15 Input no. 1 (normally the measuring element)
16 Screen (shield) for input no. 1
17 Screen (shield) for input no. 2
