1.1 Display
The user interface consists of an LCD display and a keypad
with

and

.
By using the keypad, you can display three types of
screens:
•
MEASURE Screen:
The normal display mode which
shows measured values. Pressing the
Ö
Ö
or
Õ
Õ
key
while
viewing a MEASURE screen sequentially displays these
measurements:
1. Measured Sensor A conductivity, resistivity or TDS.
2. Measured Sensor B conductivity, resistivity or TDS.
3. Measured Sensor A and B values and temperatures.
4. *Calculated Sensor A and B measurement (% reject,
% pass, ratio A/B, ratio B/A, diff. A-B, or diff. B-A).
*The calculated measurement can only be displayed when two sensors
are used and the analyzer has been correctly configured for
CALCULATION.
Pressing the
Ø
Ø
or
×
×
key
changes the bottom line (in re-
verse video) of the MEASURE screen to show these
other measurements:
➥
Measured Sensor A temperature (
°
C or
°
F).
➥
Measured Sensor B temperature (
°
C or
°
F).
➥
Analog Output 1 value (mA).
➥
Analog Output 2 value (mA).
An example of a typical MEASURE screen is:
On the MEASURE screen’s top line, Relay A, B, C, and D
annunciators will appear when their relay operational
state changes. When a relay overfeed timer is used and
it has “timed out,” the respective relay annunciator con-
tinuously blinks until the overfeed condition is resolved.
