12.
Can I change the date and time of a TV2 without losing data?
If you set the date or time
back
, the data stored in the monitor will be cleared (You will be
warned before any data is actually cleared). You can move the time forward
1 hour or
less
without losing data. A data gap will appear in the logged data. If you move the time
forward more than one hour the old data will be erased.
13.
How much data can be exported to Excel with the TView program?
When you open a file with Excel that has been saved with TView only the first 65000 data
points will be saved. (This is a limitation of the Excel program not the TV2 or TView).
The TView program has no such limitation and will save and display all data.
14. Can I move TV2 to a new location without losing data?
Yes and no. If you just unplug the TV2 and move it your data will be kept.
If you put the
TV2 into ‘Deep Sleep Mode’ you will lose some or all of your data.
Go to the Main menu
by touching 'Enter' twice and touch 'Left' to highlight 'Deep Sleep Mode'. Touch 'Enter'.
The monitor will go into a deep sleep mode during which the clock will continue to run
but no data will be logged. Once TV2 is repositioned and power supplied, touch the
screen and it will reboot. If the display does not immediately wake up press the 'Reset'
button with a paper clip. This may also cause the clock to lose some time.
15. How do I change the TV2 batteries?
Older
TV2s have 3 AA batteries inside the enclosure. Unscrew the six Phillips-head
screws and lift the back of the enclosure off.
Hold the black plastic battery holder with
your hand while you push the batteries against
the small tension spring and lift out the
batteries one at a time. Replace the batteries
and replace the back of the enclosure and
retighten the six Philips-head screws
Newer
model TV2s
have a re-chargeable non-user
replaceable battery which does not require
replacement.
16. Will an email alert identify the sensor the alert came from? Yes. It sends a message like
this:
