.USER SETTING
page
You will only see this page if the
unit is not password locked. This
page is just a warning, telling you
that all relays are frozen, and that
you can calibrate and change the
settings.
Note:
Frozen means all the relays and the analog out will maintain
their last state until the user returns to main display mode.

. CONDUCTIVITY CALIBRATION
page
1.
BASE CELL K
– this is the basic
probe cell constant. You can
choose
0.01, 0.10, 1.0
or
10
. Be
careful in changing this option
since it will set the actual cell
constant to this value and you
must
calibrate the cell constant
before you can accurately use the
unit.
2.
RANGE
– for every basic cell constant you can choose 3 different
ranges for conductivity, and an additional 3 ranges if you want
your relay controls to be in TDS. Whichever you choose you can
still view the reading in TDS or conductivity but the relay control
& current out will always be what you choose here. Choosing mS
or uS range will let the conductivity readings affect the relays set
point and the current out, choosing ppt/ppm will let the TDS
readings affect the relays and the current out. Conductivity and
TDS have the same range limit except for the units displayed.
