| Supported Units of Measurement: |
|
| Channel A: |
Pressure in Pascals, inches H2O, lb/ft2 |
| Channel B: |
Pressure in Pascals, inches H2O, lb/ft2
OR Flow in cfm, l/s, m3/s, m3/h
OR Flow @ (any pressure) calculates ELA at ANY desired pressure configured in the Setup menu
OR Leakage Area – EqLA (Canadian) and/or EfLA (US) in cm2, in2, ft2
OR Leakage Area @ (any pressure) calculates ELA at ANY desired pressure configured in Setup menu
OR Air-changes per hour according to volume entered in keypad
OR Velocity in m/s, km/h, ft/s, ft/min, mph
OR Velocity-Flow in cfm, l/s, m3/s, m3/h according to cross-sectional area entered on keypad |
| Functionality: |
|
| Range/Config: |
Cycles through flow ranges of the blower door or duct tester being used |
| Setup: |
Permits changing default units, displayed outputs, devices and reference pressures |
| Baseline: |
Measures and removes background pressures on Channel A for subequent testing |
| Time Avg: |
Advanced box-car averaging displays continuous updates of the average pressure. No more waiting for your next average pressure measurement! Dramatically reduces the affect of wind and other pressure fluctuations |
| Auto Zero: |
On start-up and every 8 seconds on both channels. May be turned off |
| Device: |
Selects the flow characteristics of virtually any blower door, duct-tester or a pilot tube |
| @: |
Turns on/off extrapolation to configured pressures |
| Volume/Area: |
Enter volume and/or area values to calculate air-change and flow/unit area results. |
| Temperature: |
Displayed with Retrotec’s temperature probe (optional) |
| Set Speed: |
Allows direct control of fan speed from the DM-2 – no need for handheld speed control |
| Set Flow: |
Closed-loop PID control of fan flow pressure – great for windy conditions |
| Set Pressure: |
Permits “set and forget” control of your fan. Dial in “Set 50 Pa” and the fan will ramp up and hold 50 Pa giving on the fly flow, ACH or leakage measurements. As you identify and seal leaks, the fan will automatically adjust itself for the tighter enclosure |
