Adjusting The Setup Values; Accessing The Setup Values; Selecting The Display Format - Robertshaw 5318B Instruction Manual

MODEL 5318B
Level Tek II, Capacitance Level Switch
If the converted format is selected the change in
displayed value is proportional to the sensed
capacitance.
For Options 1 & 3 a sampling rate of 4/second
the display will change ~50 units/1 pF change in
the input capacitance. This gives a resolution of
~0.02 pF/unit. For the 2/second sampling rate
the change in the display will be ~25 units/pF
change or ~0.04 pF/unit. Lastly at the 1/second
sampling rate the display change will be ~12.5
units/pF or 0.08 pF/unit.
For Option 2 a sampling rate of 4/second the
display will change ~100 units/1 pF change in
the input capacitance. This gives a resolution of
~0.01 pF/unit. For the 2/second sampling rate
the change will be change in the display will be
~50 units/1 pF change or ~0.02 pF/unit. Lastly
at the 1/second sampling rate the display
change will be ~25 units/1 pF or ~0.04 pF/unit.
The selection of the display format is up to the
user's preference and does not affect the
operation of the instrument. It should be noted
that setpoint values will be displayed in the
same format as the measurement.

ADJUSTING THE SETUP VALUES

Once the sampling rate and display format has
been determined the next step will be to adjust
the instruments setup values. These values are
accessible using the navigation switches located
just below the LCD display.

ACCESSING THE SETUP
4.4.3.1.
VALUES
To access the setup values press the [DN]
pushbutton once followed by pressing the [RT]
pushbutton once. The display should now show:
High SP
XXXXX
Where "XXXXX" represents the currently set
High Setpoint value. It should be noted that this
value is the result of calibrating the instrument.
This value can be changed, or tweaked, here.
Adjusting the setpoint(s) is discussed later in this
section.
4.4.3.1.1. SELECTING THE DISPLAY
FORMAT
Pressing the [DN] pushbutton six (6) more times
will bring the access to the display format
variable. The LCD display will initially show:
Where "YYYYY" represents the currently
selected display format. After a short time the
top line of the display will begin scrolling the
message:
"Select RAW measured frequency or
CONVERTED value proportional to
level"
Pressing the [RT] pushbutton once will select
this value for changing and the LCD will initially
show:
After a short time the bottom line of the display
will begin scrolling the message:
"Press RT to change mode of displayed
measurement"
Pressing the [RT] pushbutton once will open the
value for change and the LCD will initially show:
After a short time the top line of the display will
begin to scroll the message:
"Select RAW measured frequency or
CONVERTED value proportional to
level"
The [UP] and [DN] pushbuttons can be used to
scroll between the two possible value. The
currently selected format is identified by an "*"
appended to the end of the format. When the
desired format is displayed press the [RT]
pushbutton to select that format. The display
will return to the previous level of the Setup
menu.
