f. Sensor push button. Used to link the sensor to a base station.
6.
Can the wireless sensors be calibrated?
Yes. The calibration data is however, stored in the TV2 to which the sensor is linked, so
if you unlink a sensor and link it to a different display you will need to reenter the
calibration data. A sample calibration procedure can be obtained from our web site or
from the CD that came with your TV2. It is just a sample procedure. Your calibration
service or QC department may have a different procedure.
7.
How is the data transmitted from the sensor received by the display?
The display has a built-in base station that receives data from the wireless sensor. It also
stores the sensor calibration data for the sensors. The sensors transmit on 433mhz.
8.
What is the purpose of the Zoom-out and Zoom-in buttons on the TV2 chart display?
a. The amount of data displayed by the chart on the TV2 changes according to the Zoom
setting. A data point is plotted in each column if the chart is zoomed in completely
(Zoom =1X).
b. Touching the ‘
ZOOM-OUT’
button (green triangle at the bottom of the chart
display) causes more than one data points to appear in each column. The data on the
TV2 can be zoomed out 10 times (Zoom =10X). This means that the user can see
between 4 months and 256 years on one chart, depending on how often the sensor is
collecting data.
In any zoomed-out mode more than one collected measurement
appears in each column. The recorded measurements are displayed as a high-low
vertical bar.
1.
So, for example, if the TV2 is set to Zoom=2X then each column will show two
temperatures connected with a vertical line whose top is the higher temperature
and whose bottom is the lower temperature.
2.
If the chart is zoomed out further to say Zoom = 6X, the measurements (in this
case all 32 of them) will appear as a single vertical line with the highest of the
32 temperatures being the top of the line and the lowest of the 32 temperatures
as the bottom of the line. The TV2 can display between 1 and 512
measurements in each column. The
ZOOM-OUT
triangle can be touched ten
times (Zoom=10X), which will show the maximum amount of data. This
method of displaying multiple measurements in the same column allows the
TV2 to display large amounts of data in the same way that stock prices are
displayed with high-low bars covering a period of time.
9. Can I use wireless sensors inside fridges and freezers?
a. Sensors with internal Thermistors can be used within a fridge but the range is
decreased, and the cold temperature will also shorten the battery life of the sensor.
