2.3 Glossary
This section discusses the terminology used throughout this manual.
System impedance
Component density and ventilation structure obstruct the flow of air and cause
pressure loss within a device. This resistance to the flow of air within a device is
known as system impedance. It is also referred to as ventilation or system resistance.
This resistance and airflow rate can be plotted using a quadratic curve. This is known
as a system impedance curve. The intersection of the P-Q performance curve and
system impedance curve is known as the operating point.
Operating airflow
Refers to the actual airflow within a device while a fan is mounted.
P-Q performance (airflow vs. static pressure characteristics)
Expresses the relationship between airflow and static pressure of a fan.
Connection duct
Connects the measured device to the main unit. (Included)
Measurement nozzles
These nozzles are used to calculate airflow. Each nozzle has a different measuring
range. For more details, see section 4.2, "Measuring range of the measurement
nozzles." With the assistance of the automatic feedback control, change the nozzles
to match the measured airflow range. For more details, see section 4.3, "Automatic
feedback control of the measurement nozzles." The nozzles are inserted into the side
of the main unit, dividing it into two chambers. Airflow is calculated by measuring the
difference in static pressure in both chambers. Five sizes of nozzles are included to
deliver accurate airflow measurement.

Auxiliary fan
The auxiliary fan is located at the rear of the main unit. It is used to create a pressure
difference between the two chambers separated by the nozzle. The operation of this
fan is automatically controlled during measurement.
Mode selection valves
These are two valves that are used to switch between measurement modes. Set the
mode selection valves to match the measurement mode. For more details, see
section 3.2, "Setting the mode selection valves."

3. Getting started
3.1 Preparing the main unit
Some preparation of the main unit is necessary for measurement.
①Connect the AC power cable to the main unit
and insert it into an outlet.
(The POWER LED lights red when the main
unit is receiving power.)
②Turn the power switch to the ON position.
When the power is turned on, all of the LEDs
blink three times to confirm functionality.
After about five seconds, the control
panel enters the start-up status (as
shown on the right) and you may begin
using the tester.
Check that the POWER LED lights
green and the STATUS LED is off.
When the power is turned on, nozzle
No.1 and SYSTEM IMPEDANCE are
initially selected.
Note: If there is a problem with the equipped sensors for temperature, humidity,
or atmospheric pressure, the control panel displays an error code.
For further details, see section 7, "Troubleshooting." Follow the instructions
corresponding to the error code.

3.2. Setting the mode selection valves
On the side of the main unit, adjust the mode selection valves as shown in the diagram
below.
3.3 Inserting and exchanging the measurement nozzles
The measurement nozzles need to be replaced to measure different measuring ranges.
For further details, see section 4.2, "Measuring range of the measurement nozzles."
When inserting and replacing the measurement nozzles, follow the procedure provided
below.
①Detach the nozzle slot cover from the main unit.
Release the two snap locks and detach the cover.
②Insert the nozzle as shown in the diagram below.
Firmly insert the nozzle along the groove within the nozzle slot.
The tester may not function properly if the
nozzle is not completely inserted.
When replacing nozzles, remove the inserted
measurement nozzle and insert a different one.

Units of measurement: m3/min, CFM, Pa, inchH2O
Units are set prior to shipping and cannot be changed by the user.
⑦START/STOP button
START: Begins measurement for all measurement modes
Used to begin manual measurements. Six measurements are taken during P-Q
performance mode: three automatically and three manually.
STOP: Hold down for approximately four seconds to cancel measurement
Also cancels measurement for each measurement mode.
Hold down until the green STATUS LED turns off.
Length of time to hold the button may vary depending on the measurement status.
4.2 Measuring range of the measurement nozzles
Included are five sizes of measurement nozzles numbered 1 to 5. The numbers are
stamped into the nozzles. Each measurement nozzle is specially designed to measure a
particular airflow range.
Measuring range of the measurement nozzles
No. 1: 0.20 m3/min to 0.42 m3/min
No. 2: 0.42 m3/min to 0.90 m3/min
No. 3: 0.90 m3/min to 1.90 m3/min
No. 4: 1.90 m3/min to 3.90 m3/min
No. 5: 3.90 m3/min to 8.00 m3/min
During measurement, the internal automatic feedback control determines the most
appropriate nozzle for measurement.

20
4.3 Automatic feedback control of the measurement nozzles
The Airflow Tester is equipped with an automatic feedback control to determine the correct
nozzle for a measurement. The feedback control automatically judges whether or not the
selected nozzle is appropriate for the current measurement.
If the nozzle is incorrect, an error code indicating to replace the nozzle appears on the data
display, the STATUS LED lights red, and the measurement stops.
Replace the nozzle in accordance with the error code.
Push START/STOP to clear the error and return to standby mode.
Once in standby mode, the red STATUS LED turns off.
①If the current nozzle is too big:
Error code "E002" appears on the display so use a nozzle one size smaller.
[Ex] If you had used nozzle No. 3, replace it with nozzle No.2.
②If the current nozzle is too small:
Error code "E001" appears on the display so use a nozzle one size larger.
[Ex] If you had used nozzle No. 3, replace it with nozzle No.4.
Note: For further details, see section 3.2, "Inserting and replacing the measurement
nozzles."
4.4 Checking the status of the main unit (CHECK mode)
This tester has a function that automatically checks the status of the internal sensors.
The procedure for using CHECK mode is explained below.
In CHECK mode, nozzles are optional. (Selecting a nozzle is unnecessary.)
Perform the following checks after detaching the duct from the main unit.
①Turn on the power, then check on the control
panel that the POWER LED lights green and
the STATUS LED is off.
②Simultaneously hold down NOZZLE and MODE
and the CHECK LED flashes green.
When the LED lights green,
CHECK mode is enabled.
