Meter Description 

1. 

LED display

 for Air Velocity, Air Flow, Probe 

Temperature, and remote surface temperature. Units 
of measurement and user alerts are also displayed on 
the LCD. 

2. 

Vane Sensor

. Hold the sensor in the flow of air to take 

a reading. 

3. 

IR sensor: 

Non-contact temperature measurement for 

remote surfaces. 

4. 

Laser Pointer: 

Helps the user aim the IR sensor. 

5. 

Battery access: 

Cover on rear panel 

6. 

PC interface jack: 

Use the supplied cable to connect 

meter to a PC 

7. 

Upper Keypad

 (brief descriptions below): 

 

IRT: 

Press and hold to measure remote surface temperature. Release to hold the 

temperature value on the display.

 

 

MAX/MIN (for air temperature measurements)

: Used to record and store the highest 

and lowest readings for temperature measurements made by the vane probe. 

 

AVG

: Used to obtain Average for multi-point measurements in either FLOW or 

VELOCITY modes. Up to twenty (20) points can be averaged. 

 

HOLD 

 (for air temperature measurements): 

Press to freeze the displayed 

temperature reading measured by the probe. Press again to unlock the display. Press 
and hold for 2 seconds to activate the LCD backlight. Press and hold again for 2 
seconds to turn the backlight off. 

8. 

Lower Keypad

 

 

On/Off button 

: Press to turn the meter ON or OFF 

 

MAX/MIN   (for air velocity and air flow)

: Press to record and store the highest, 

lowest and continuous moving average readings for single point measurements. This 
button also functions as the decimal positioning tool in the AREA mode. 

 

C-F UNITS

: Press to select the mode of operation and unit of measure. In FLOW 

mode, the meter displays air volume. In VELOCITY mode, the meter displays air speed. 
This button also functions as the UP arrow button in AREA mode. 

 

AREA / NEXT

: Press and hold to enter the AREA mode. The NEXT function allows the 

user to save AREA values to any of eight memory locations. This button is also used to 
clear stored readings in the MAX/MIN/AVG modes. 

 

HOLD   (for air velocity and air flow measurements) Backlight:

 Press to freeze the 

displayed air velocity or air flow reading. Press again to unlock display. This button also 
functions as the right arrow button in the AREA mode. 

NOTE

: Battery Compartment and Tripod Mount are located on the reverse side of the meter
