The instrument can operate in two modes:
 Stand-alone mode, described in this section
 Remote mode, in which the instrument is controlled by a computer running DataView (see §4)
3.1. Making Measurements
3.1.1. Air Speed
1. Connect the sensor to the instrument.
2. If the instrument is OFF, press and hold down the button until it turns ON.
3. Press and hold down the button. While holding this button down, short-
press the button to cycle through the measurement options until VELOC
appears on the LCD.
4. While continuing to hold down , short-press to select the air speed
units of measure. Options are M/S (meters per second), F/M (feet per
minute), KM/H (kilometers per hour), and M/H (miles per hour). When the
desired measurement is displayed, release .
5. To change temperature units, short-press .
6. Hold the sensor in the air flow. The arrow on the inside of the propeller must point in the direction of the
flow (see illustration to the left). This ensures the temperature sensor faces the incoming air, allowing it to
display an accurate value more quickly.
7. The air speed and temperature measurements are displayed on the LCD. (Wait for the measurements to
stabilize before accepting the reading.)
Always hold the sensor by its handle. Keep your fingers away from the sensor propeller.
Note that if you turn the instrument OFF, the configuration settings selected in steps 1 through 6 above will still be
in effect the next time you turn the instrument ON.
3.1.2. Air Flow (Volume)
The Model 1227 can measure air flow both with and without using an optional air flow cone. Cones are typically
used for measuring air flow through grated ventilation registers and other passages where the flow is disrupted
and distorted, resulting in inconsistent measurements. The cone can help "normalize" the air flow by directing
most or all the air towards the instrument's sensor, providing a more consistent measurement. Two models of
cones are available as accessories, one with a round 7.9” (20cm) opening, and the other with a square 13”
(33cm) opening.
Thermo-Anemometer Data Logger Model 1227 9

Before you begin, ensure the instrument is turned ON and connected to the sensor. Then do the following:
1. Press and hold down the button. While holding this button down, short-press the button to cycle
through the measurement options until the desired FLOW setting appears on the LCD. Choices are:
In - measures incoming (blowing) air flow with a cone.
out - measures outgoing (suction) air flow with a cone.
CUSt - measures air flow without a cone. If you select this option, you must enter the area of the
ventilation register into the DataView Data Logger Control Panel, as explained in step 4 below. The
instrument can then calculate air flow using the speed measurement and ventilation area setting.
2. While continuing to hold down , short-press to select the air flow units of measure. Options are
M3/S (cubic meters per second), M3/H (cubic meters per hour), L/S (liters per second), and CF/M (cubic
feet per minute). When the desired measurement is displayed, release .
3. To change temperature units, short-press .
4. If you are using an air flow cone: Skip the remainder of this step and proceed with step 5 below.
If you are not using a cone: Connect the instrument to a computer using DataView (§2.2). Select the
instrument in the Data Logger Network and click Instrument -> Configure. Then go to the Anemometer
tab, select Custom, and enter the area of the ventilation register. (Consult the DataView Data Logger
Help system for assistance.) When finished, place the sensor in front of the ventilation register, and go to
step 7 below.
5. Place the air flow measurement cone on the sensor. Depending on the measurement you want to make
(flow in or flow out), place the sensor with the arrow pointing towards the cone (outgoing flow) or away
from it (incoming flow).
6. Place the cone on the ventilation register. The arrow inside the propeller must point in the direction of
the air flow. This will be towards the outside of the cone for a blowing measurement, or towards the inside
of the cone for a suction measurement.

3.1.4. MAX AVG MIN Function
You can monitor the maximum, minimum, and average measurements by pressing the button.This displays the
words MIN/AVG/MAX at the top of the display (see the following illustration). In this mode, pressing once
displays the maximum value measured during the current session. A second press displays the average value,
and a third displays the minimum. Finally a fourth press restores the normal display. Subsequent presses of
repeat this cycle.
To exit MAX AVG MIN mode, long-press . Note that when MAX AVG MIN mode is active, the MAP function is
deactivated.
3.1.5. MAP Function
The MAP function enables you to map air speed, air flow, or temperature for a 2-dimensional space or surface.
For example, in MAP mode you can measure the air speed at specific points within a room. You can then
download the recording to a computer running DataView, and display the measurements as a 2-dimensional
matrix, creating a “map” of the air speed within the room.
Before mapping an area, it is good practice to create a chart identifying where to make measurements. For
instance, the following illustration is an example measurement chart for a room. Each red circle represents a
measurement point.
To enter MAP mode, press for >2 seconds. Place the sensor at the first measurement point and press to
record the value in memory. The MAP counter is incremented. Repeat this step for all the other points of the map.
Thermo-Anemometer Data Logger Model 1227 11

When all points have been measured, you can display the maximum, average, and minimum values. To do this,
press three times to cycle through the maximum, average, and minimum values respectively.
To exit MAP mode, long-press .
For each map, a file is created containing all measurement points. This file can then be downloaded and
analyzed.
3.2. Recording Measurements
You can start and stop a recording session on the instrument. Recorded data is stored in the instrument’s
memory, and can be downloaded and viewed on a computer running the DataView Data Logger Control Panel.
You can record data by pressing the button:
 A short press (MEM) records the current measurement(s) and date.
 A long press (REC) starts the recording session. While the recording is in progress, the symbol REC
appears at the top of the display. A second long press of stops the recording session. Note that while
the instrument is recording, a short press of has no effect.
