Examples
Example - RPM display
A proximity sensor connected to a flywheel produces 20 pulses per revolution. The instrument is
required to display in RPM with 1 decimal point place. In this example 20 pulses per second would
equal 1 revolution/sec which equals 60 RPM. The
RAtE INPt
figure and
RAtE SCLE
figure
could be
20
and
60.0
respectively but we will use
1
and
3.0
since they give the same ratio and
hence will give the same reading on the display.
1. Follow the procedure shown on page
to enter the setup functions via
CAL
mode.
2. Step through the functions by pressing and releasing
F
until the
RAtE dCPt
function is
seen.
3. Use the
^
or
v
push button to change the setting to
0.1
.
4. Press
F
, the function
RAtE INPt
will appear followed by the previous input value.
5. Use the
^
or
v
push button to alter the previous input value to the new input value of
1
.
6. Press
F
, the function
RAtE SCLE
will appear followed by the previous scale value.
7. Use the
^
or
v
push button to alter the previous scale value to the new scale value of
3.0
.
8. Press
F
to accept the change then either press
P
to exit of continue pressing and releasing
F
until the
FUNC End
message is seen and the unit returns to normal measure mode.
Example - Low frequency input rate display
A transducer is being used to give one pulse out for every bottle passing a point on a track. The
display is required to show bottles per hour. The number of bottles passing can be as low as one
every five seconds up to two per second. The
RAtE INPt
value will be
1
and the
RAtE SCLE
value will be
3600
i.e. 1 bottle per second = 3600 bottles per hour. The procedure is as follows:
1. Follow the procedure shown on page
to enter the setup functions via
CAL
mode.
2. Step through the functions by pressing and releasing
F
until the
FREQ RNGE
function is
seen.
3. Use the
^
or
v
push button to change the setting to
LoF
.
4. Step through the functions by pressing and releasing
F
until the
t.out SECS
function is
seen.
5. Use the
^
or
v
push button to change the setting to a value greater than
5
seconds e.g.
8
.
6. Step through the functions by pressing and releasing
F
until the
RAtE INPt
function is
seen.
7. Use the
^
or
v
push button to change the setting to
1
.
8. Press
F
, the function
RAtE SCLE
will appear followed by the previous input value.
