Congratulations!
Your TV2 with easy touch will provide years of reliable service, collecting, storing and displaying
data while monitoring temperature,relative humidity, and differential pressure. 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 you can navigate to the
menu screens, a temperature history chart for each sensor, zoom in or out of a chart to see more data,
set the alarms, silence an alarm, set the data storage rate, and much more.
Sensor Accuracy:
The TV2 logs and displays information it receives from its sensors. The accuracy of that data
depends on the sensors. The digital wired sensors are accurate to ±0.3°C, the wireless thermistor
sensors are accurate to ± 0.3°C and our thermocouple sensors are accurate to between ±1.0°and
±2.2°C depending on the type of thermocouple. Humidity sensors have an accuracy of ±3%. (See the
chart on page 4). Differential pressure sensors have a degree of uncertainty of ±0.002” w.c.

Powering the TV2 Display:
The TV2 display is powered via a USB cable, which can be plugged into a computer or the wall plug
(100vac-230vac). An optional DC connector is also available which will accept 5-30 volt dc.
Lithium backup batteries are installed in the TV2 and will keep it running for over 100 hours if
normal power is missing. The batteries are not user serviceable, but like all lithium batteries will
gradually lose their ability to be recharged so that after five years they will only have enough charge
to power the TV2 for 72 hours. After 7 years the display should be returned to 2di for battery
replacement.
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, during which time the display will go
dark, to conserve battery power. Once power is restored the display will wake up.
Internal Alarm & Relay:
The TV2 has a dry contact normally open (N/O) relay and piezo buzzer, which are activated when an
alarm occurs. (See appendix for alarm types)
Factory Service and Returns:
Please call for a return authorization (RA) prior to sending any instrument for repairs. (see page 39
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 (computer or wall plug) and touch the LCD. If the
display remains blank press the reset button by inserting a paper clip into the small hole to the
left of the green LED on the face of the TV2. (see page 10).
This display will appear.
2. Touch ‘Up’ or 'Down' to select C° or F° and touch ‘Enter’. The highlight will move to the
next field.
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) date.
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: If you move to another field by touching ‘Right’ your changes will not be recorded).
5. Touch ‘Escape’. You will be asked to verify that you want to erase all data. Touch ‘Right’ to
highlight YES and touch 'Enter'.
6. Touch 'Escape' to return to the previous menu.
The TV2 is now set and operating.
Next the TV2 will help you setup sensors & alarms

Setting up sensors
1. Plug the wired sensor into the TV2, or if you are using wireless sensor, place a 9vdc battery in
the transmitter that is attached to the actual sensor.
2. After a few seconds, the TV2 will recognize the sensor and change the display to the Sensor
Setup menu. The “Show Max/Min on Main Status” will be highlighted. Leave it as yes and
touch Enter
3. The hour area of the log data field will be highlighted.
Note: If the TV2 does not 'see' your sensor you will need to link it or
plug it into the TV2. The linking procedure is found in FAQ- pg 33.
4. This determines how often the sensor will log or store a temperature. You may scroll to any
value between 1 min and 24 hrs with 'Up' or 'Down', touching 'Enter' to move to the next field,
or accept the default by touching 'Enter'. The default value is ten minutes (00:10:00).
5. 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 max & min temperatures (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 falls outside these limits will show as a point at the top or

P O Box 159 •Crestwood, KY 40014 •[phone] • [phone] fax
www.e2di.com • [e-mail]
the bottom of the display. Note: These limits can be adjusted at any time without affecting
your data.
Setting the sensor alarms
6. Highlight ‘Set Alarm’ and touch ‘Enter’.
7.
8. The alarm for this sensor is disabled by default. To enable the alarm touch '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 will sound and the relay will be closed.
Note: If you are using an auto-dialer set it for at least 00:22 (22 seconds) but not
longer than 06:00 (Six minutes).
B. Scroll in the alarm upper limit and delay time and then the alarm lower limit and its delay
time 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 (or below) the set
temperature before the alarm occurs. This helps prevent false alarms.
9. You do not need to enter the Calibration Menu at this time. (For calibration procedures see the
document Entitled ‘Calibration Procedures’ found on the support page of the www.e2di.com
website. It can also be downloaded from our website here.
10. Touch 'Escape' until you return to the Status Screen.
You are done!

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 power the TV2 from your computer, you will be able copy data (auto
download) from the TV2 as well as send email or text alerts. Auto Downloading copies the
logged data stored in the TV2 monitor to your computer every few seconds.
2. Sensors:
a. Wired Sensors. Decide where you are going to place each sensor. Each senor has a 20-foot
wire which needs to be run to the TV2 display. (Extension wires are available in fifty-foot
lengths).
b. Wireless Sensors. Position the sensors. If the sensors are inside a refrigerator or freezer
position the transmitter (the black box) outside the refrigerator or freezer so the signal can
be transmitted back to the TV2.
3. Power for TV2. Plug the USB cable into the TV2 into a USB port on a computer or into the
power cube (wall plug) supplied.
4. Backup Battery - A non-user serviceable Lithium ion battery is installed in the display unit to
provide temporary power during a power outage. If a power outage occurs, the display will turn
off to decrease the load on the battery, however the battery will eventually run out. Fully
charged batteries will operate the TV2 in sleep mode for ~ 72 hours, depending on how often
you are logging data.
Frequent power outages should not drain the batteries, although a power outage longer than 72
hours could drain the battery. If the battery is completely depleted your data will still be
preserved, since it is saved in non-volatile RAM, but no new data will be logged. The Lithium
Ion battery will be automatically recharged once AC power is restored to the TV2.
Operational Tip: If the power to the TV2 is interrupted, an alarm will sound, and the relay
will close. This 'power out' alarm can be disabled on the Main Menu if desired.

The LEDs and reset button at the bottom center of the display.
The green LED blinks once a second, indicating the
display is logging data. During a power outage this
LED will continue to blink, indicating that it is
collecting and logging data 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 green and red LEDs is the 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).

To make a change:
1. Make sure the proper field is highlighted by touching ‘Left' or 'Right' until the desired field
is reached. If the last field on the page is highlighted touching 'Right' will move the highlight to
the first field on the page.
2. Once the field is highlighted, change the value by touching 'Up' or 'Down'. The appropriate
values will be scrolled through.
3. Touch 'Enter' after selecting the proper value.
Note: It is possible to move to the next field by touching 'Right' but your change will not
be saved. The change is only finalized by touching 'Enter'.

The Current Status Display
The TV2 main display (current status) will change depending on how many sensors you are receiving
data from. If you have one sensor plugged into or linked to the TV2, the display will look like the
one below.
Once you plug a second sensor into the TV2 the current status screen will change to show both
sensors, (see below).

Operational Modes
The TV2 has three operational modes: Main; Chart; and Sleep.
Main Mode
The screen is divided into sections showing each sensor's current reading along with the maximum
and minimum temperature recorded for that sensor.
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 sensors violated an alarm
condition, in which case it will be 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 wireless sensor is not linked to the TV2, a message stating "Sensor Not Installed' will be
displayed in that quadrant.
3. If a wireless sensor has been linked to the display but no signal is being received, a message
stating "Sensor out of Range" is displayed.
4. If wireless sensors are being used the battery strength for that sensor is shown. If the battery
level drops below 20% the number turns red, rather than the normal green color. (No
battery strength is shown for wired sensors).

P O Box 159 •Crestwood, KY 40014 •[phone] • [phone] fax

5. The battery icon shown at the bottom of the current status display is for the TV2 internal
rechargeable backup-battery.
To see a history chart for a sensor, touch that sensor's temperature on the display.
1. The temperature scale which appears as the Y-axis of the chart, is set in the sensor setup
menu. (There could be temperatures above or below the Y-axis limits)
2. The number in the upper right-hand corner of the display indicates which sensor’s chart is
being shown (sensor 2 in this example).
3. The time line along the top of the chart, the X-axis, indicates when the values, in this case
temperature, 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 35 for an explanation of this feature)
Use the hotspots to switch charts. Lightly touching any of the four temperatures on the bottom of the
display will immediately change the screen to show that sensor’s temperature history 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.

Touching anywhere in body of the chart adds four navigation buttons as shown below so you can
view additional information.
Touching the bottom blue triangle doubles the amount of data displayed on the chart (see zoom in
FAQ). The top blue triangle zooms into the display, so less data is displayed. The green triangle
on the left scrolls backward, showing older data, while the green triangle on the right shows more
recent data. To return to the status screen touch 'Escape'.
