Standard

This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

Changes or modifications not expressly approved by Sauermann could voice the user’s authority to operate the equipment.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:

1. This device may not cause interference, and
2. This device must accept any interference received, including interference that may cause undesired operation.

Air velocity displayed on the instrument is calculated at fixed conditions: L Pitot tube with a deprimogen coefficient of 1.0015, at 20°C (68°F) and 1013.25 hPa (29.92 inHg). When the app is used to display air velocity, these parameters can be modified.
All the accuracies indicated in this technical datasheet were stated in laboratory conditions, and can be guaranteed for measurements carried out in the same conditions, or carried out with calibration compensation.

General features

*Battery life given at 20°C (68°F) with alkaline batteries
**If the instrument is stored outside the operating temperature (for example in a van, a warehouse, etc.), please wait for 10 minutes in its operating temperature before starting and using it.

Operating principle

Calculation of saturation pressure
This parameter must be calculated for air velocity calculation with the Si-PM3 differential pressure manometer instrument.
Psat: Saturation pressure (unit: Pa) H: Relative Humidity (unit: %RH) T: Temperature (unit: Kelvin K)

Calculation of air density
This parameter must be calculated for air velocity calculation with the Si-PM3 differential pressure manometer instrument.
ρ: Air density (unit: kg/m3)
Patm: Atmospheric pressure (unit: Pa) T: Temperature (unit : Kelvin K) Psat: Saturation pressure (unit: Pa)

Use with a pitot tube

The Pitot tube is introduced perpendicular ipe by pre-determined points by the user.
The antenna is composed of an ellipsoidal nose (bow) maintained in parallel and in front of the flow to control.
The Tp total pressure (+) is picked up by the bow and is connected to the + sign of the manometer.
The Sp static pressure (-) picked up by the small holes located around the antenna is connected to the – sign of the manometer.
The difference between these two pressures is the pressure indicated on the Si-HVACR Measurement MobileApp and is equal to the dynamic pressure Dp = Tp- Sp.

Maintenance

Change batteries

•  With the device turned off.
• Unscrew the battery compartment at the back of the device and remove the cover.
• Remove used batteries and insert new batteries (3 alkaline batteries AAA LR03 1.5 V) respecting the polarity.
• To close the battery compartment, push the battery cover back on starting with the upper part.
• Screw the battery compartment cover.

Clean the instrument

• Clean the housing with a damp cloth (soap suds) if it gets dirty.
• Do not use aggressive cleaning agents or solvents.

Warranty

Instruments have 2-year guarantee for any manufacturing defect.
