The TV2 is an entirely new type of data logger. Most data loggers
must be programmed with a computer, deployed, allowed to collect the data
and then downloaded into a computer. The logged data can not be seen
until the final step has been completed.
The TV2 is a completely stand alone data logger. It
never has to be plugged into a computer. Setup is done on the
logger itself using the Easy-Touch™ display. It is designed
for long term logging of multiple sources. It is normally powered
from a wall transformer or a computer via a USB cable. And although it does
contain a lithium battery the battery is there for emergency use only powering
the TV2 for at least 72 hours if a power failure occurs.
Temperarture history on the TV2 (no computer
The logged temperatures can be seen on the TV2 itself two different ways.
First the maximum and minimum temperatures for each sensor appears next
to the current temperature, and secondly if you touch one of the temperatures,
the display changes to a chart showing all logged data for that sensor.
Logs 80,000 temperatures for each sensor
A logged data can be displayed as a continuous chart by touching a temperature
on the Easy-Touch™ Display. The data chart can be scrolled through to see
individual data points. You can also zoom out of the display to see all
of the stored samples on the screen at one time, so that trends are easy to
spot. If zoomed all of the way out as much as one and one half years of data
can be seen on one screen if you are logging a data point once very ten minutes.
In addition to seeing a temperature chart for each sensor every individual data
point can be see with the trace mode, which can be used to scroll the data.
By moving back and forth through the logged data you can see exactly when each
individual reading was taken. It is possible to scroll through 80,000
individual temperatures for each sensor. This makes it easy to pinpoint
a temperatures high point and see when it occurred, how long it lasted and whether
it was a spike or a slow ramp up in temperature.
Although the TV2 is a very sophisticated instrument it is eay to install. Positioning
each sensor, setting the sample interval, and setting the date and time of the
TV2 is about all there is to it. The display and alarm parameters can also
be set using the on-board menu.
The TV2 has its own internal alarm so that if a temperature gets too high
or too low, an alarm goes off and a
normally open (N/O) relay is triggered so you are notified with a phone call,
email, or instant message immediately. And all of this happens right inside
the TV2. It does not have to be wired up to a computer
or the Internet for the phone alert. The text and email alert does require
that the TV2 be plugged into a comptuer.

The TV2 can be interfaced with a computer via the USB port or the Wired Ethernet
connector to autodownload the data. Logged data can be copied to an Excel file
or printed out as a chart. The software is also used to configure the email
alert system so the user is notified any time an alarm occurs.

The TV2 is the only stand alone data logger that
also charts, alarms and displays data.
