or
T.Comp Range

If
A: Cond Units
is set to
USP645
(AX450 and AX455 analyzers only - see page 22),
the temperature coefficient is fixed automatically at 2.00%/ºC.
Enter the temperature coefficient (a x 100) of the solution (0.01 to 5.0%/ºC). If unknown,
the temperature coefficient (a) of the solution must be calculated - see appendix A.1.1
on page 74.
If the value has not yet been calculated, set it to 2%/ºC provisionally.
TDS Factor
Note.
Displayed only if
A: Cond.Units
is set to TDS - see page 22.
The TDS factor must be programmed to suit the particular application - see appendix
A.2 on page 74.
Enter the required TDS factor between 0.4 and 0.8.
For salinity applications, set the TDS factor to 0.6.
TDS Units
Note.
Displayed only if
A: Cond.Units
is set to
TDS
Select the TDS units (ppm, mg/l or mg/kg).
Enable Calibration
Select
Yes
to enable sensor calibration - see section 4.1, page 17.
If
No
is selected the calibration menu, pages and frames for the relevant sensor are not
displayed.
Sensor B configuration (dual input analyzers only) is identical to Sensor A configuration.
Single input analyzers only - return to main menu.
