Boky Torolalana ho an'ny Manometra Nomerika Dwyer 475-1-FM

1. Fampidirana

The Dwyer 475-1-FM Handheld Digital Manometer is designed for fast, accurate positive, negative, and differential pressure measurements. This device is suitable for use with air and compatible combustible gases. Its robust design and intrinsic safety features make it ideal for various industrial and scientific applications, including HVAC system monitoring, clean rooms, fume hoods, and isolation cabinets.

2. Information momba ny fiarovana

2.1 Intrinsically Safe Operation

The Dwyer 475 Series Manometer is FM-approved intrinsically safe for Class 1, Div. 1, Group A, B, C, D, T4 hazardous locations. Adhere to all local and national safety regulations when operating in such environments.

2.2 Gas Compatibility

This manometer is compatible with air and compatible combustible gases. Do not use with incompatible or corrosive gases, as this may damage the instrument and pose a safety risk. Always verify gas compatibility before connecting the manometer.

2.3 Fitandrina ankapobeny

• Ensure the manometer is in good working condition before each use.
• Fadio ny milatsaka na mametraka ilay fitaovana amin'ny fiantraikany mafy.
• Do not attempt to open or repair the unit yourself, as this may void the warranty and compromise intrinsic safety.
• Arovy amin'ny mari-pana sy ny hamandoana tafahoatra ny fitaovana.

4. Fametrahana

4.1 Fametrahana bateria

1. Locate the battery compartment cover on the back of the manometer.
2. Esory ny fonony.
3. Insert the supplied 9V alkaline battery, ensuring correct polarity.
4. Soloy tsara ny fonon'ny efitrefitra bateria.

4.2 Tubing Connection

The manometer features two barbed connections for tubing. These connections accept 1/8" (3.18 mm) or 3/16" (4.76 mm) I.D. tubing.

1. For positive pressure, connect the tubing from the pressure source to the positive (+) port.
2. For negative pressure (vacuum), connect the tubing from the vacuum source to the negative (-) port.
3. For differential pressure, connect the higher pressure source to the positive (+) port and the lower pressure source to the negative (-) port.
4. Ensure tubing connections are snug to prevent leaks.

5. Torolàlana miasa

5.1 Mamelona/Mamono

• Tsindrio ny ON/OFF bokotra hampandeha ny fitaovana.
• Tsindrio ny ON/OFF tsindrio indray ny bokotra mba hamonoana ny fitaovana.

5.2 Auto Zero Function

Before taking a measurement, it is crucial to zero the instrument for accuracy.

1. Ensure both pressure ports are open to atmospheric pressure (disconnected from any pressure source).
2. Tsindrio ny ZERO button. The display will show '0.00' or a similar indication, confirming the zeroing process.

5.3 Pressure Unit Selection

The manometer allows selection between U.S. and metric pressure units.

• Tsindrio ny vondrona button to cycle through available pressure units (e.g., in. w.c., kPa).
• Select the desired unit for your measurement.

5.4 Fandrefesana

1. Perform the Auto Zero function as described in Section 5.2.
2. Connect the tubing to the appropriate pressure source(s) as described in Section 4.2.
3. The large LCD will display the pressure reading in the selected units.
4. The manometer can display positive, negative, or differential pressures.

6. Fikojakojana

6.1 Fanadiovana

Wipe the exterior of the manometer with a soft, damp lamba. Aza mampiasa mpanadio na solvents mikikisana, satria mety hanimba ny c ireoasing na fampisehoana.

6.2 Fanoloana bateria

When the battery indicator appears on the display, replace the 9V alkaline battery following the steps in Section 4.1. A fresh battery provides up to 100 hours of operation.

6.3 Fitehirizana

Store the manometer in a dry, cool place, away from direct sunlight and extreme temperatures. Disconnect tubing and remove the battery if storing for extended periods to prevent leakage.
