1. SAFETY INFORMATION
The following symbol may appear on the instrument and in this instruction
manual:
Refer to Instruction Manual
CAUTION
When using the meter to check air flow, make certain that you can safely raise and hold
the meter while making measurements. Be especially careful when working on a
ladder.
Observe all necessary precautions so that the unit does not become caught in moving
machinery or touch any exposed electrical wiring.
DANGER
The meter is not designed for use in gas mixtures other than air. DO NOT use the unit
with corrosive or other dangerous or explosive gas mixtures.

5. MEASURING PROCEDURE
5-1 Getting Started
1. Installing the Batteries
Insert six AAA batteries as indicated by the diagram located on the inside of the
battery compartment.
2. Extending the Probe
To extend the probe, remove the sensor protection cap, hold the handle in one
hand while pulling on the probe tip with the other hand. Do not hold the cable while
extending the probe as this prevents the probe from extending.
3. Using the flexible telescoping probe
The flexible telescoping probe contains the air velocity sensor. When usingthe probe,
remove the sensor protection cap then rotate or bend the flexible tube, make sure the
sensor windowis fully exposed and is facing upstream.
※
※※
※If in the right direction, the user will see the red-ink marking as following figure.
4. Retracting the Probe
To retract the probe, hold the handle in one hand while pushing on the probe tip with
the other hand. If you feel the probe antenna binding, pull gently on the probe tube
until the flexible tube section is retracted. Collapse the rest of the antenna by
pressing the probe tip and refit the sensor protection cap.
