RATE
Changing the sampling rate can be accessed by
pressing the [DN] pushbutton once from the
"Display" variable. The display will initially show:
Sampling
X/sec
Where "X" represents the currently selected
number of updates per second. After a short
time the top line of the display will begin to scroll
the message:
"Use lower sampling rate only for high
capacitance probes"
Pressing the [RT] pushbutton once will select
the value and the LCD will initially show:

The [UP] and [DN] pushbuttons can be used to
scroll among the three possible values. The
current sampling rate is identified by an "*"

FAIL-SAFE MODE SELECTION

Once the sampling rate and display mode have
been set the next logical item to be set is the
Fail-Safe Mode. The Model 5318B provides two
fail-safe modes; high level (HLFS) and low level
(LLFS).
HLFS is the mode in which the "Alarm" condition
exists when the sensed level is above the High
Setpoint. The alarm then clears, returns to
normal, when the level falls bellow the Low
Setpoint.
Conversely, LLFS is the mode in which the
"Alarm" condition exists when the sensed level is
below the Low Setpoint. The alarm then clears
when the level rises above the high Setpoint.
To select the required fail-safe mode enter the
Setup Menu, from the normal operating mode by
pressing the [DN] pushbutton, followed be
pressing the [RT] pushbutton. This action will
bring you to the first item in the Setup Menu,
High SP.
Pressing the [DN] pushbutton three (3) times will
bring you to the 'Alarm ON" variable. The
display will initially show:
Where XXXX represents the currently selected
fail-safe mode. After a short time the top line of
the display will begin to scroll the following
message:
Pressing the [RT] pushbutton once will select
the value and the LCD will initially show:

After a short time the bottom line of the display
will begin scrolling the message:
Pressing the [RT] pushbutton once will open the

fail-safe mode. After a short time the top line of
the display will begin to scroll the following
message:
The [UP] and [DN] pushbuttons can be used to
scroll among the two possible values. The
current fail-safe mode is identified by an "*"
appended to the end of the format. When the
desired fail-safe mode is displayed press the
[RT] pushbutton to select that rate. The display
will return to the previous level of the Setup
menu.
