Press
F1
to select the
LIN
(linearity)
option. The instrument prompts for
a linearity value.
If a parameter is not specified, make
certain it is set to zero. Key in 0 and
press
ENTER
.
Press
F2
to select the
SCALE
(scale
factor) option.
At the scale prompt, key in the trans-
ducer scale factor and press
ENTER
.
Press
F3
to select the
OFFS
(offset)
option.
At the offset prompt, key in the trans-
ducer offset and press
ENTER
.
Now press
F4
to select the
DELAY
option.
Key in a warmup delay of 1000 mSEC
(milliseconds) and press
ENTER
.
The HERMIT 2000 will power the
transducer for one second before tak-
ing a reading.
Note:
The warmup delay is rarely specified on third-party transduc-
ers and must often be determined by experiment. In-Situ’s standard
transducers use a warmup delay of 50 mSEC unless specified other-
wise. A one-second delay is used here only for the purpose of ex-
ample.
Press
CLEAR
to exit the parameter
menu . . .
. . . and return to the first input setup
menu. Press
F1
to select the
READ
option.
The HERMIT 2000 will power the
input channel and wait for the pro-
grammed warmup delay period . . .
. . . and then take a transducer read-
ing and turn off the input channel.
We are warned that no transducer
has been connected to the input
channel.
If a transducer had been connected, the HERMIT 2000 would have
displayed the reading in the programmed units. Press
ENTER
to
take additional readings from the same transducer. These readings
will confirm that the transducers are properly connected and that
you have programmed the transducer parameters correctly. For this
example, we will leave the transducer disconnected.
Press
CLEAR
to return to the trans-
ducer menu.
Press
CLEAR
again to return to the
READY
display. We’re now ready to
start collecting some data.
Starting the Test
From the
READY
display, press the
START/
STEP
key.
The instrument displays the start
menu. Press
F1
to select an
IMME-
DIATE
start.
The data point display flashes briefly
to indicate that a data point has been
recorded at an elapsed time of 0 min-
utes.
We are then returned to the
READY
display. Notice that a test
RUNNING
indicator has been added.
The HERMIT 2000 will record a transducer reading once every
minute until you
STOP
the test or all the available data storage space
is used up.
As you continue with the example,
you will be interrupted occasionally
as the instrument takes another data
point.
Viewing Recorded Data
From the
READY
display, press the
VIEW DATA
key. Recorded data can be viewed while the test
is running or after the test is stopped.
You are prompted to enter a test
number for viewing (you can also
view tests other than the one that is
running). The default selection is the currently running test or the
highest test that has been run. Press
ENTER
to select our sample
test.
Next select the test step. Press
ENTER
to select step 0.
