...8.2 No Response to Conductivity Changes
Failure to respond to the input indicates a fault with the analyzer
which must be returned to the Company for repair. A response,
but with incorrect readings, usually indicates an electrical
calibration problem. Re-calibrate the analyzer as detailed in
Section 7.3.
b) If the response in a) is correct, reconnect the conductivity cell
cable and connect the resistance box to the cell end.
Check the analyzer displays the correct values as set on the
resistance box in this configuration.
If the analyzer passes check a) but fails check b), check the
cable connections and condition. If the response for both
checks is correct, replace the conductivity cell.
8.3 Checking the Temperature Input
Check the analyzer responds to a temperature input.
Disconnect the Pt100/Pt1000 leads and connect a suitable
resistance box directly to the analyzer inputs – see Section 7.2.
Check the analyzer displays the correct values as set on the
resistance box – see Table 8.3.
