Start up

Battery Operation

For portable use, the monitor will operate up to 70

hours on 4 AA industrial alkaline batteries. The batteries can be installed by
removing the battery cover and following the diagram imprinted on the back
plastic cover.

LOW BATT

flashes when there is less than 30 minutes of battery life. At

this point the batteries should be replaced or the AC adapter should be
used as a substitute. If operation continues, the unit will become
inoperable and only the

LOW BATT

will be blink on the LCD display.

AC Power Operation

The sensor is shipped with a 6V DC

500mA AC/DC adapter. To use the adapter, connect the plug into the
back of the unit and plug the transformer into any standard wall outlet.

NOTE

Use the supplied adapter. The wrong adapter may cause damage

to the unit. Battery operation will not function as a back up during a
power loss.

Power-Up

1. Press the Power Button and a 2 second delay will occur before the

display becomes visible.

US Standard to Metric Conversion

The Temperature, Ventilation rates and Elevation Readings can be
viewed in US Standard or Metric readings. The Temperature is converted
from Fahrenheit (°F) to Celsius (°C), the Ventilation Rates are converted
from Cubic Feet Per Minute Per Person (cfm/p) to Liters Per Second (l/p/
s) and the Feet (ft) to Meters (m).

Operation

Elevation Correction -

The

sensor, like any other gas
measuring device is affected
by altitude changes. The
sensor is shipped with the
elevation setting set at “zero”
or sea level. If you are at an
altitude greater than 500 feet,
an adjustment should be made
to assure maximum sensor
accuracy. Once the elevation
correction is set it will be
stored and saved in the
monitor memory. To change
the default setting follow the
steps below.
1. Press the

Mode

button until

ELEVATION

begins to blink.

2. Press

Enter

3. Press

Mode

to toggle the

elevation reading between
feet(ft) & meters(m).

4. Use the

Up/Down

button to

adjust the altitude in increments of 500(ft) or 100(m). Once the correct
altitude is set, press

Enter

to save the setting and return to normal mode.

Temperature or CFM/Person –

The lower display will cycle through the

following units when the

Up/Down

button is pressed: Temp°F, Temp°C,

CFM, turn lower display off.

Stand-alone Monitoring -

Once Elevation correction has been made (as

described in the steps above), the sensor will begin to accurately display
current room conditions.

Using an External Datalogger

- Voltage outputs for both CO

and

temperature are available via an RJ-45 jack on the rear of the unit.

The Telaire

7001 is an easy-to-use hand-held CO

/Temperature

monitor. The unit provides stable, highly accurate readings due to
our patented dual beam NDIR technology. Equipped with a 0-4V
output, the unit is perfect for long-term monitoring/recording.

Ventilation Rate (cfm/p)

Overview

- Press the

up/down

button until cfm/p is displayed. This value

represents how much outside air is being introduced on a CFM per
person basis. The reading is derived from calculating the outside air
ventilation rate to a space based on the inside/outside CO

differential

readings. Current codes/standards generally require 15 to 20 CFM/
Person to be delivered to most spaces to ensure acceptable air quality.
Low values indicate low ventilation rates and potentially poor air quality.
High levels can indicate excessive ventilation and potential excessive
energy usage. To obtain accurate measurements, readings should be
taken 2 to 3 hours after occupancy has stabilized in a space or at a peak
in daily CO

concentrations.

Adjusting the Outside CO

Concentration

The sensor is factory set to assume an outside level of 400 ppm, which
should be close to the outside concentration in most areas. The outside
level of CO

can also be changed by measuring outside levels or by

manually adjusting the monitor.
1. Power up outside and wait for CO

levels to stabilize (approx 5 min).

2. Save the reading by holding the

Enter

button on the sensor for 5 secs.

3. This value is used to calculate the ventilation rate based on the

differential of the measured outside value and into measured inside
concentration.

Manual Input of Outside Concentration

The monitor is factory set at 400 PPM. To adjust the factory setting (for the
cfm/person calculation) or to verify the current setting follow steps below:
1. Press the mode button until

and

ppm

flash.

2. Press the enter button and the current outside value will display.
3. Use the

Up/Down

button to increase/decrease the CO

value.

4. Press enter to save and store the value in the monitor.

Calibration (CO2)

IMPORTANT -

The sensor has been factory calibrated and should need

calibration once every 12 months using either a zero concentration gas or a
gas with a specified concentration of CO

. For the most accurate field

calibration we recommend purchasing a Telaire calibration kit (P/N 2075).
Sensor drift usually occurs at the zero reference point. The manual calibra-
tion process allows the user to perform a one point calibration based on
ambient levels or by flowing a gas of a known concentration through the
sensor. This process will adjust the zero offset of the sensor and will provide
an accurate calibration. If a two point calibration is required the Calibration
kit should be used. For manual calibration, follow the steps below.
1. The calibration procedure will last approximately 15 minutes. Before

performing the calibration procedure, remove the battery cover to

access the calibration activation switch. Connect the supplied AC adapter
to the back of the sensor or ensure new batteries are installed.

2. Power up the sensor and wait for the Warm-up to end.
3. Next verify the Elevation correction has been set. Refer to the steps in

Elevation Correction for procedure.

4. If you are calibrating to ambient conditions make sure the sensor is

displaying a stable reading - avoid breathing in the area of the monitor.
If you are flowing gas to the calibration port of the sensor, allow the
gas to flow for at least 10 minutes before initiating calibration.

5. Press the

Mode

button twice. The Calibration mode will begin blinking.

5. Press

Enter

6. Use the

Up/Down

button to adjust reading to the current ambient

conditions or concentration of the gas being used. Pressing the button
once will change the readings in increments of 10 ppm. To increase
the speed, press and hold the button.

NOTE

- For best accuracy, a reference or known concentration of CO

should be used when adjusting the reading. Bottled nitrogen can be used
to provide a zero concentration gas.
7. Next, on the backside of the unit locate the push button switch (under

the battery cover, in the small round hole to the right of the connector
jack), use a small pointed object to depress and hold the switch for 5
seconds.

will begin to blink.

8. Press Enter.

Calibration In Progress

will begin to blink. At this point the unit will

program itself based on the CO

value that was input in Step 6. The

calibration process will take approximately 5 minutes.

When Calibration is complete, the display will return to the steady

Calibration

mode. Press

Enter

to return to the normal operation mode.

Temperature Adjustment

Use this procedure to adjust the temperature output when you wish to
have the temperature output match a reference sensor. The accuracy of
a field adjustment is dependent upon the stability of the environment is
which the procedure is performed, and upon the accuracy of the refer-
ence sensor.
1. Connect the supplied AC adapter to the back of the sensor. If you do

not have the AC adapter, new batteries should be used.

2. Power up the sensor and place in a stable environment, free of drafts

or temperature changes. Wait 30 minutes for the unit to fully equili-
brate with the environment. Do not hold the unit in your hand during
this period. Press the mode button until the blinking word

TEMPERA-

TURE

appears.

4. Press

Enter

. Both the word

TEMPERATURE

and the numeric

temperature display will begin blinking in unison.

5. Use the

Up/Down

button to adjust the temperature reading to match

the reference.

6. Press

Enter

. The temperature offset is immediately adjusted, the

blinking stops, and the unit is now in normal operating mode.
