1 Camur II Anode Ladder Quick 1 For automatic monitoring of Anode Ladder and Drill Core Anode 1 sensors Description The Camur II Anode Ladder node monitors automatically LPR, ZRA, resistance, potential and temperature. The inputs are galvanically separated from the bus side.

For two-wire Pt1000 sensors, connect P1+ with P1 and P2- with P2. The analog inputs are not galvanically separated from each other. Recording types Page 2 of 5

3 The Anode Ladder node supports recording types Monitor, Monitor Extended and LPR in Camur II software. Outputs from measurements in standard format reports a list of the measurements of each sensor in the format: [sensor name]-[value type], one column for each combination. Measurements that belong to the same sample interval are collected in one row. Measurement reports Monitor Value / type Unit Measurement I 1 ma Current between A1 and C I 2 ma Current between A2 and C I 3 ma Current between A3 and C I 4 ma Current between A4 and C I 5 ma Current between A5 and C I 6 ma Current between A6 and C I 7 ma Current between RC and C R 1 k Ω Resistance between A1 and A2 R 2 k Ω Resistance between A2 and A3 R 3 k Ω Resistance between A3 and A4 R 4 k Ω Resistance between A4 and A5 R 5 k Ω Resistance between A5 and A6 R 6 k Ω Resistance between A6 and RC R 7 k Ω Resistance between RC and C T C Temperature U 1 mv Potential between A1 and RE U 2 mv Potential between A2 and RE U 3 mv Potential between A3 and RE U 4 mv Potential between A4 and RE U 5 mv Potential between A5 and RE Page 3 of 5
