INTRODUCTION
An instrument panel has a 4-digit display, a mode dis-
play,
a 8-key keyboard, and 3 LED indicators. A picture of
the panel is shown in Figure 3.1.
3.2
DISPLAY AND INDICATORS
The
4-digit displays the value corresponding
to
the
mode-display. A decimal point between the second digit and
the
third digit will always light up when power is on.

TEMPERATURE COMPENSATION
For automatic temperature compensation, a pH/RTD probe
will be used. The 1000nRTD element (Resistance Temperature
Detector) is a thin film platinum chip that is embedded
in
the body of the pH probe. It is a stable temperature device
that
has
the
same
time response as
the
pH
probe
to changes in temperature as
shown
and
responds

For manual temparature compensation, a regular pH
probe
will be used and a 1000n fixed resistor is used
