Congratulations!
Your TV2 with easy touch will provide years of reliable service, collecting, storing and displaying
data while monitoring temperature and relative humidity. Although it is a highly sophisticated
instrument it is easy to install and use.
The Display:
The LCD display is a full color easy touch display. With a simple touch on the display you can
navigate to the menu screens, a temperature history chart for one of the sensors, zoom in or out of a
chart to see more data, set the alarms, silence an alarm, set the data storage rate, etc...
Sensor Accuracy:
The TV2 logs and displays information it receives from its sensors. The accuracy of that data
depends on the sensors. The internal and external thermistor sensors are accurate to ± 0.3°C and
thermocouple sensors are accurate ±1.0° to ±2.2°C depending on the type of thermocouple.
Humidity sensors have an accuracy rate of ±3%. (See the chart on page 4).
Display Power:
The TV2 display is powered via a USB cable from a computer or the wall plug. An optional DC
connector is also available which will accept 5-30 volt dc. Backup batteries (AA) are installed in the
TV2 and will keep it running for about 40 hours if USB power is missing. The batteries can be
replaced by removing the back of the TV2 enclosure (see page ?? ).
Sensor Power:
Wireless sensors are powered by a 9-volt battery with a normally life expectancy of ~ 1 year.
Operating on batteries:
If normal USB power fails and the ‘Missing AC alarm’ is active, the internal buzzer will beep in 1
second intervals for 60 seconds, sleep for 10 minutes, then beep every second for another 60
seconds, etc.. At the same time the TV2 will enter a light sleep mode after 20 seconds to conserve
battery power. The display can be awakened for 20 seconds with a touch.
Note: Repeatedly waking a display running on batteries will shorten the life of the batteries.
Internal Alarm & Relay:
The TV2 has a dry contact normally open (N/O) relay and piezo buzzer, which are activated when
alarm conditions occur.
Factory Service and Returns:
Please call for a return authorization (RA) prior to sending any instrument for repairs. (see page 34
for warranty information).

Quick Start
Your TV2 can be installed and operating in just a few minutes by following these simple steps.
1. Connect the TV2 to a power supply and touch the LCD.
This display will appear.
2. Touch ‘Up’ or 'Down' to select C° or F° and touch ‘Enter’.
3. Touch ‘Up’ to select the date format (MM/DD/YY, DD/MM/YY or YY/MM/DD) and then
'Enter'. The date format defaults to the US style (MM/DD/YY).
4. Set the day, month, year, hour and minute in the appropriate field by scrolling through the
possible values with 'Up' or 'Down' after moving to the appropriate field with 'Enter'.
(Note: It is possible to move to another field with the ‘Right’ button but your entries will not
be recorded).
5. Touch ‘Escape’. You will be asked to verify that you want to erase all data. Use ‘Right’ to
highlight YES and touch 'Enter'.
6. Touch 'Escape' to return to the previous menu.
The TV2 is now set and operating. Next TV2
will help you setup sensors and alarms

Setting up sensors
1. Install a 9-volt battery in each sensors.
2. After a few seconds, the TV2 will recognize the sensor and change the display to the Sensor
Setup menu. The hour area of the sample data field will be highlighted.
Note: If the TV2 does not see your sensor you will need to link it.
The linking procedure is found in the FAQ on page 30.
3. This is how often you want the sensor to store a temperature). You may scroll to any value
between 1 min and 24 hrs with 'Up' or 'Down', touching 'Enter' to move to each field, or
accept the default by touching 'Enter'. The default value is ten minutes (00:10:00).
4. Select the type of averaging with 'UP', or 'Down' and touch 'Enter'. There are three possible
selections.
a. Fast – no averaging occurs. The exact measurement at the time of sampling will be
stored and displayed. (Not normally used except during calibration)
b. Medium- some averaging will take place so that minor temperature fluctuations will be
filtered out. (This is the default value).
c. Slow – additional averaging will occur. (Not normally used).
5. Set the chart display (Y axis) with ‘Up’ and ‘Down’.This does not set the alarm. Setting
these values has no effect on the alarm, what data is collected, or what is stored. It simply
sets the upper and lower point of the Y-axis of the temperature chart shown on the TV2. Any
temperature that cannot be displayed on the chart screen because it falls outside these limits
will show as a point at the top or the bottom of the display.
Note: These limits can be adjusted at any time without affecting your data.

Setting the sensor alarms
6. Set the Alarm by highlighting the ‘Set Alarm’ button and touching ‘Enter’.
7.
8. . Enable the alarm by touching 'Up' and then 'Enter'.
A. Set the trigger-alarm-time to any value between 0:00 and 99:00. This controls how long the
alarm and the relay will be activated.
Note: If you are using a dialer set it for at least 00:30 (30 seconds) but not longer
than 06:00 (Six minutes).
B. Scroll in the upper alarm limit and delay time and then the lower alarm limit and delay with
'Up’ and ‘Down’ touching 'Enter' to move to each field in turn.
Note: The delay time is how long the temperature must remain above the limit before the
alarm occurs.
9. You do not need to enter the Calibration Menu at this time. (For calibration procedures see the
document Entitled ‘Calibration Procedures’ on the CD. It can also be downloaded from our
website http://www.e2di.com/PDFs/Calibration Procedures.pdf)

Installation tips
1. Planning - Position the TV2 display close to an AC power source or your computer. The TV2
receives its power via a USB cable, which can be plugged into a computer or a wall
transformer. If you can power the TV2 from your computer you will be able to auto-
download data from the TV2. Auto Downloading data causes the TV2 data to be copied to
your computer every few seconds.
2. Wireless Sensors. Decide where you are going to place each wireless sensor. Each senor has a
transmitter that sends the data to the TV2. The range of the transmitter is 100 feet clear-line-
of-sight. Walls or furniture between the sensors and the TV2 will decrease the range. Use the
signal strength meter on the Status Screen to insure you have adequate reception. Allow three
seconds to elapse after moving a sensor before evaluating the signal strength
3. Power for TV2. Power is supplied through a USB. If you power the TV2 from your
computer the TView software can auto download to your computer, updating the alarm log and
initiating email alerts if alarms occur.
4. Backup Battery - Three AA batteries are installed in the display unit to provide temporary
power during a power outage. If a power outage occurs, the display will go to sleep after 20
seconds to decrease the load on the batteries, however the batteries will eventually run out.
Fully charged batteries will operate the TV2 in sleep mode for ~ 40 hours, depending on how
often you are sampling data.
Frequent power outages can drain the batteries. The icon in the bottom center of the display
showing remaining battery life should be checked frequently. Any time the icon appears less
than 1/3 full, the batteries should be replaced. This is done by removing the six screws on the
back of the display and replacing the three AA batteries with new ones.
Note: If the battery voltage drops too low you will warned to replace the internal battery.
Your stored data will not be affected even if the batteries are completely dead or removed as
all settings and data are stored in non-volatile memory. If a low battery condition does
occur it is recommended that you copy your data to a PC with the TView software as an
extra safety measure.
Operational Tip: If the power to the TV2 is interrupted, an alarm will sound and the relay
will close. This alarm can be disabled on the Main Menu if desired.

The LEDs and reset button at the bottom of the display
The green LED blinks once a second, indicating the
display is collecting data and working normally.
Even during a power outage this LED will continue
to blink, indicating that it is collecting and storing
temperatures from the sensors
The Red LED blinks when the display is operating
on batteries. If an alarm occurs it will glow a
steady red.
The small hole on the left of the red and green LEDs is a reset button. Insert the paper clip slowly
until you feel the button press down. It will pop back up as soon as you release the paper clip and a
system reset will occur. (Your settings and data will be preserved).

On the System Setup menu you can change the temperature scale, the date and time, activate a
password to restrict access to the menu system, and reset all values to the factory default.
To make a change:
1. Make sure the proper field is highlighted. To highlight a field, touch 'Left' or 'Right' until it
moves to the desired field. If the last field on the page is highlighted touching 'Right' will
move the highlight to the first item on the page.
2. Once the field is highlighted, change the value by touching 'Up' or 'Down'. Appropriate
values will be scrolled through.
Note: The longer you touch the button, the faster it will scroll through the possible
choices. Once it reaches the last choice it will wrap around to the first possible choice.
3. Touch 'Enter' when you have the proper value showing. It is possible to move to the next
field by touching 'Right' but your change will not be saved. The change is only finalized when
you touch 'Enter'.
Operational Tip: Touching ‘Up’ or “Down’ scrolls through possible values at a fast rate.
The longer you hold your finger on the screen, the faster it scrolls.

Operational Modes
The TV2 has four operational modes: Main; Chart; Trace, and Sleep.
Main Mode
The screen is divided into four quadrants showing four sensor's current reading as well as the
maximum and minimum temperature recorded for that sensor. Each sensor's signal strength and
battery capacity is also shown underneath the temperature.
Elements of the display:
1. A current temperature and relative humidity, if appropriate, is displayed in large green
letters. The max/min readings are also shown in green, unless one of the temperatures
violated an alarm limit, in which case it will be in red.
Note: It is possible a max or min temperature was too high or low but an alarm was
not triggered. This would happen if the violation was shorter than the delay time.
2. If a sensor is not linked to the TV2 a message stating "Sensor Not Installed' will be
displayed in that quadrant.
3. If a sensor has been linked to the display but no signal is being received, a message stating
"Sensor out of Range" is displayed.
4. The signal and battery strength for the sensor is shown. If either of these values drops
below 20% it is displayed in red, rather than the normal green color.
5. The battery icon shown at the bottom is for the TV2 backup-battery.

To see a chart for a sensor, touch that sensor's temperature.
1. The temperature scale appears as the Y-axis of the chart, which was set in the sensor setup
menu. (There could be temperatures above or below these values)
2. The number in the upper right hand corner of the display indicates which sensor’s chart is
being displayed.
3. The time line along the top of the chart, the X-axis, indicates when the temperatures were
collected. The dates on this line will change if you scroll left or right, or zoom out or in to
view additional data.
4. The bottom two rows of the display show the current day and time along with the most recent
reading from each sensor. Also shown, at the bottom right of the screen, is the zoom level.
(See FAQ on page 30 for an explanation of this feature)
Use the hotspots to switch charts. Lightly touching any of the four temperatures listed on the bottom
of the display will immediately change the screen to that sensor’s temperature chart.
Note: The TV2 stores a lot of data but eventually it fills up. Once it does, the newer
data rolls over the oldest data. If you are sampling data every 10 minutes the last 1.5
years of data will be stored and can be viewed.

Sleep Mode
1. In Sleep Mode, the display is blank. The TV2 automatically enters sleep mode after power has
been missing for 20 seconds, to preserve the battery. The TV2 will still collect data and
perform all other functions during the sleep mode. TV2 can be ‘awakened’ for twenty seconds
by touching the screen.
2. The TV2 operates normally while running on batteries except that it is not as bright.
3. Alarms will still be triggered during the sleep mode and any visual warnings will display as
they occur.
Note: A deep sleep mode can be selected on the main menu, to turn off the TV2. In
this mode only the clock continues to run. To exit from deep sleep touch the TV2 after
supplying power.

Calibration data entered here will be stored in TV2 so if a sensor is moved to a different TV2
you will need to reenter the calibration data.
Each sensor can have up to three different calibration points. When the calibration screen
opens, only one point is listed, but you can add two additional points or remove points.
The measured value that is shown when this screen opens is the temperature shown on the
status screen, and the actual value is what it should be reading. If the measured value needs to
be adjusted to agree with your comparison thermometer move to that field and touch 'Up' or
'Down' to scroll in the correct value.
How TV2 uses this data:
1. One point – Any temperature will be offset from the measured value.
2. Two Points – Any temperature will be adjusted by the offset equal to the point on a line
drawn between the two points.
3. Three Points – Any temperature will be adjusted by the offset equal to the point on a line
drawn between the three points. The line could be straight or the slope between point 1
and 2 could be different than the slope between point 2 and 3.
(Suggested calibration procedures can be copied from the support page on the 2di web site or
the CD that came with the TV2)
