Operation
Power ON-OFF
Power the meter ON or OFF by pressing and holding the power key for at least 1.5 seconds.
Meter Functions
This meter has three modes of operation: Air velocity (with temperature), thermocouple
temperature, and Air Volume (CFM/CMM). Press and hold the FUNCTION key for at least 1.5
seconds to switch from one mode to the other.
Air Velocity plus Temperature mode; meter displays
An
icon.
Type K or J thermocouple temperature mode (meter displays
tP
icon).
Air Flow (Volume CFM/CMM) meter displays
F-US
or
F-EU
depending how the meter is set up
for units of measure for area; refer to the SETUP mode for details.
Air Velocity plus Temperature Mode
1.
Select the Air Velocity and Temperature mode as described above.
2.
Connect the vane probe to the meter’s probe jack (top right of meter) via the probe plug.
3.
Hold the probe by its handle and allow the air flow to enter the sensor area. Note that the air
flow must face the probe’s colored dot.
4.
The meter will display the air velocity measurement (upper display area) and the air
temperature (lower display area).
Changing the Air Velocity Unit of Measure
This meter offers five (5) units of measure selections for air velocity: m/s (meters per second), FPM
(feet per minute), Km/h (kilometers per hour), knots, and mph (miles per hour).
1.
Press and hold the UNIT key for at least 1.5 seconds to switch from one unit of measure to
another.
2.
Note that pressing and holding the UNIT key continuously allows for quicker scrolling. Release
the key when the desired unit of measure is displayed.
Thermcouple (Type J or K) Temperature Mode
1.
Select the Thermocouple Temperature mode using the FUNCTION button as described above.
2.
The meter will display a ‘J’ or a ‘K’; on the left side of the display indicating the selected type.
To change the thermocouple type, refer to the Setup Mode section.
3.
Connect a Type J or Type K thermocouple to the meter’s sub-miniature thermocouple jack (top
of meter on the left).
4.
Hold the thermocouple in the air in the area to be tested.
5.
The meter will display the thermocouple temperature in the main display area.
6.
To change the temperature unit of measure (°C and °F) refer to the Setup Mode section.
