reset to ‘off’ if 1.16 is set to ‘on’.
1.16
0…50 μS/cm conductivity range
Specify if the controller will read electrical conductivity of
permeate in the range of 0…50 μS/cm (on/off). This setting will reset
to ‘off’ if 1.15 is set to ‘on’.
1.17
Permeate conductivity Fault threshold
Specify maximum acceptable permeate conductivity. Conductivity
reading above this value will initiate Fault
mode (‘High permeate
TDS’). If set to zero,
fault threshold will not be used.
1.18
Permeate conductivity Fault delay
Specify the length of time before the controller goes into Fault
mode when high permeate conductivity is being read.
1.19
Temperature probe
Select whether temperature probe is used (on/off).
1.20
Set permeate temperature
Specify temperature of permeate for correct conductivity
measurement. Only active if 1
.19 is ‘off’.

2.1
First point value
First calibration point can be done at zero electrical conductivity (dry
conductivity meter). In order to use zero first point conductivity, remove
the conductivity meter from its cell, wipe with clean cloth and keep dry
for a few minutes. When conductivity reading on the display stabilizes,
put zeroes in the bottom row, and go to the next step.
If using a weakly conducting solution to set the first point, rinse the
meter with deionized water and wipe dry. Dip clean conductivity meter
