DATA HANDLING
The function of the instrument is to provide useful and reliable data.
Accurate recording and handling of the data is essential if it is to be
of any value.
6.1
Monitoring the Load Cell Readings
Geosense
®
HLC
-
6000 Series Hydraulic Anchor Load Cells
contain a temperature
sensor within the VW transducer. Where a load cell is installed in a zone where its
temperature is likely to fluctuate significantly, records of both load and temperature
data should be used to assess any affects that temperature have on the data (see
section 6.6).
6.2
Portable Readouts
Geosense offer a range of readout and data logging options. Specific operation
manuals are supplied with each readout device.
Below is a brief, step

portable
readout.
1.
Connect signal cable from the sensor to the readout following the wiring colour
code. Conductor colours may vary depending upon the extension cable used.
Commonly these are:
RED
=
VW +
BLACK
=
VW
-
GREEN
=
Temp
WHITE
=
Temp
2.
Press the
‘
On/Off
’
button to switch the unit on.
Press it again to acquire a reading from the
connected instrument.
3.
The readout displays the Vibrating Wire readings in both
‘
Frequency
’
(in Hz) and Linear
‘
B
’
Digits (in Hz
2
/1000).
Temperature reading in both resistance (Ohms) and
degrees C.
For more details see the readout manual.
4.
Press and hold down the On/Off
’
button to switch the
unit off.
Whilst it is not critical that the polarity be observed for most
Vibrating Wire instruments, a better signal may be obtained if
the correct polarity is adopted. Since the temperature sensor
is a Thermistor, its connection polarity is not important.
