1.3 MEASURE Screen
(normal display mode)
☞
The MEASURE screen is normally displayed. Pressing the
MENU key
temporarily replaces the MEASURE screen with
the “MAIN MENU” branch selection screen. Using the key-
pad, you can then display other screens to calibrate,
configure or test the analyzer.
If the keypad is not used
within 30 minutes, except during calibration and while
using specific analyzer test/maintenance functions, the
display will automatically return to the MEASURE
screen.
To display the MEASURE screen at any time, press
the
MENU key
once and then the
ESC key
once.
Pressing the
Ø
Ø
or

key
with the MEASURE screen dis-
played scrolls between other measurements on the bottom
auxiliary display line. These MEASURE screen examples
illustrate this feature:
NOTE:
The MEASURE screen will show an asterisk after
the pH reading to indicate pure water temperature
compensation if it was selected (PART THREE,
Section 4.2, subheading “Select Pure H2O COMP”).
When the analyzer returns to its normal MEASURE
screen mode, the appearing readout is always the
version last selected.
Note that these MEASURE screen examples show
“BASIN 1” notations on their top lines, illustrating
the analyzer notation feature. To create your own
notation, refer to PART THREE, Section 4.2, sub-
heading “ENTER NOTE (top line of MEASURE
screen).”
When a measured value is beyond the analyzer measuring
range, a series of “ + ” or “ - ” screen symbols appear,
respectively indicating that the value is above or below
range.
