Flowserve LRGT16-1 Spector compact Conductivity Transmitter System - Manual (Page 16)

Inaccurate readings
Fault:
Indicated conductivity higher than measured comparison value.
Remedy: During commissioning: Reduce temperature coefficient Tk.
During operation: Reduce cell constant.
Fault:
Indicated conductivity lower than measured comparison value.
Remedy: During commissioning: Increase temperature coefficient Tk.
During operation: Increase cell constant.
Fault:
The measurement result can no longer be adjusted by changing
the cell constant.
Remedy: Remove equipment and clean measuring surface.
Exchanging electronic insert
1. Undo lid screws and remove both housing lids.
2. Unscrew fixing screws of cover plate and remove the plate.
3. Pull electrode wires from terminal lugs on circuit board. Plug out the lower terminal
