 Equivalent leakage area per enclosure area at 10 Pa, “EqLA10/area”: sq in/sq ft, sq cm/sq m)

 Effective leakage area per enclosure area at 4 Pa, “EfLA4/area”: (sq in/sq ft, sq in/100sq ft, sq ft/sq

ft, sq cm/sq m)

The [Channel B] display is also a key: when tapped, the “Result to display” on [Channel B] will change. In

the list that shows up, tapping a [Result] to highlight it (in brighter red), will select it as the displayed

[Channel B] Result of choice. Once highlighted, the [Result] can be tapped repeatedly to cycle through all

the different units available for display of that Result.

Refer to Retrotec’s Residential & Commercial Airtightness Requirements document for Results required

according to various standards, codes, and regions.

2.6.3. Set the [Range/Device] connected to the gauge

“Device” refers to the calibrated fan or other device being used to conduct the current test in conjunction

with the gauge. It is important to make sure that the correct Device is selected because the calculation for

each of the Results is based on equations that are different for each Device.

“Range” or “Range Configurations” are the rings or plates installed on a calibrated fan to limit the air flow

through it, so that the fan can achieve a measurable Fan Pressure, even when moving only a small amount

of air (for more information, see Retrotec’s Manual-Door Fan Operation). Select the Range that matches

the Range Ring or Plate that is installed on the fan to ensure that the gauge performs accurate calculations

and displays correct results.

Retrotec calibrated fans connected to the gauge with a Speed Control Cable can have their speed of

operation controlled by the gauge through the “Fan Speed” control output.

Fans manufactured by TEC (such as the DuctBlaster or Minneapolis Model 3 or 4) can be controlled by the

gauge “Fan Speed” control output if an optional Retrotec-TEC Fan speed control Adapter is connected

between the gauge and the TEC fan, in line with the Speed Control cable as shown in Figure 12. The

Minneapolis fan speed control must have the cruise input.

Connecting the pressure tubing to your TEC fan as described in Retrotec literature allows the gauge to

correctly calculate results.
