Checking The Temperature Input - ABB AX410 User Manual

Single and Dual Input Analyzers for Low Level Conductivity
AX410, AX411, AX413, AX416, AX418, AX450, AX455 & AX456

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,
page 61. Check the analyzer displays the correct values as set
on the resistance box - see Table 8.3.

Table 8.3 Temperature Readings for Resistance Inputs
Incorrect readings usually indicate an electrical calibration
problem. Re-calibrate the analyzer as detailed in Section 7.3.
