Description

The Greenlee ANM-50 Anemometer and Thermometer is a hand-held testing

device for measuring three different characteristics: velocity (speed), flow

(volume of air per unit of time), and temperature. Useful for checking the output

of HVAC/R systems, the ANM-50 can take single-location measurements or

multiple-location measurements.

The ANM-50 can display either metric or U.S. units of measure.

Safety

Safety is essential in the use and maintenance of Greenlee tools and equipment.

This instruction manual and any markings on the tool provide information for

avoiding hazards and unsafe practices related to the use of this tool. Observe all

of the safety information provided.

Purpose

This instruction manual is intended to familiarize all personnel with the safe

operation and maintenance procedures for the Greenlee ANM-50 Anemometer

and Thermometer.

Keep this manual available to all personnel.

Replacement manuals are available upon request at no charge.

Operation

1. Turn the unit on. After performing a self-test, the unit will display the

temperature and air velocity.

2. If the unit does not function as expected, replace the battery.

3. If the unit still does not function as expected, send the unit to Greenlee for

repair. See the address shown under Warranty.

4. See Basic Functions and Advanced Functions for detailed operating

instructions.

Typical Measurement

•Place the unit in the airstream. For highest accuracy, ensure that the airstream

and the sensor are aligned (±20 degrees maximum) as shown.

•Allow at least three seconds for the reading to stabilize.

Electric shock hazard:

Contact with live circuits can result in severe injury

or death.

Basic Functions

Metric and U.S. Measurement Scales

Use this procedure to select either metric scale (Celsius for temperature and

meters per second for airflow) or the U.S. scale (Fahrenheit for temperature and

feet per minute for airflow).

1. Turn the unit off.

2. Press the AVERAGE MULTI-POINT button and hold.

3. Press the ON-OFF RESET button and release.

4. Release the AVERAGE MULTI-POINT button after the LCD shows the

measurement scales.

5. Press the AVERAGE MULTI-POINT button to select the U.S. scale.

Press HOLD to select the metric scale.

6. Press the MIN/MAX REC button and release. The letter “S”will appear on the

display.

7. Press HOLD and release. A four-digit number will appear on the display.

8. Press the MIN/MAX REC button and release. The letter “S”will appear on the

display.

9. Press HOLD and release. The display will return to normal.

Measurement Units

In addition to selecting a measurement scale (metric or U.S.), you may also

select one of several measurement units. After turning the unit on, press and

release the SEL: -MPH -KNOTS key to cycle through the choices:

The choices will appear in this order:

• Metric: Meters per Second

•

Kilometers per Hour

•

Advanced Functions

Air Velocity Average (Multiple Locations)

1. If the unit is on, press and hold the AVERAGE MULTI-POINT button until the

unit beeps twice to erase any stored data.

Turn the unit on. When “vel”appears in the upper left corner and the

temperature appears in the lower right corner, the unit is ready to take a

measurement.

2. Place the unit in the airstream.

3. After taking the measurement, press and release the HOLD button.

You will hear a tone and HOLD will appear on the display.

4. Press the MIN/MAX REC button.

You will hear a tone and a single digit (1 –8) will appear on the display.

This digit is the location number.

5. Repeat Steps 2 –5 until all of the locations have been tested, up to the

maximum of 8 points.

6. Press the AVERAGE MULTI-POINT button.

The display will show the average air velocity measurement and the number

of locations tested.

Air Flow Measurement (Single Location)

Air flow, or volume of air per unit of time, is calculated by multiplying the air

velocity by the free area of the grill or register. This specification is available from

the grill or register manufacturer.

1. Turn the unit on.

2. Press the MODE VELOCITY FREE AREA FLOW button.

AREA and 1.111 will appear on the display.

The leftmost digit will flash.

If this is correct for your application, proceed to Step 3.

Otherwise change the area value as shown below.

•Press the HOLD button to increment the flashing digit.

•Press the AVERAGE MULTI-POINT button to advance to the next digit.

Press the MODE VELOCITY FREE AREA FLOW button to save the information.

FLOW will appear on the display.
