The ADMN2 is a portable dual port manometer accessory head for use with Fieldpiece's modular multimeters (DMMs) and instruments. Measures gas pressure, static pressure and pressure differential. The ADMN2 includes a zero adjust and the Auto Power-Off (APO) function conserves battery life. Disable APO for data logging. The ADMN2 measures pressure between -60inWC and 60inWC (inches of water column) and -150.0 to 150.0 mBar. The ADMN2 also measures P1 or P2 pressure readings and calculates the difference between P1 and P2. Take static pressure measurements using the resolution mode of 0.01inWC or 0.01mBar.
The modular design of the ADMN2 gives it a distinct advantage over other dual-port manometers in the field. Remoting the ADMN2 with Fieldpiece's detachable test leads allows you to measure pressure in hard to reach places. The included 3/16" to 5/16" adapters allow you to measure gas pressure on more makes and models of gas appliances as well.
How Does It Work?
Use the ADMN2 to measure gas pressure, static pressure and pressure differential. Simply connect to COM and Volts jacks on your meter using any Fieldpiece test leads with removable probe tips. For Fieldpiece "stick-style" meters, adapters and handles, slide the head directly onto the unit. Select the mVDC range on your meter. Remove the rubber strip on the face of the ADMN2 to access the ZERO button. Press the ZERO button while the tubes are disconnected to calibrate the meter to ambient pressure. Then use the meter as you wish to perform the following tasks:
- Connect a single hose to get the gauge pressure relative to the ambient or ZERO pressure
- Connect both hoses if you want to see relative pressure, P1 minus P2. Select P1, P2, or P1 - P2
Then select English (inches of water column) or Metric (mBar) units. To disable the auto-power-off, remove the rubber covering and flip the switch below. Auto Power-Off is helpful for conserving the battery; but if you are data logging with Fieldpiece model DL3, you will want to disable this feature. If you are in an environment where the temperature is noticeably changing while you are taking your reading, disconnect the meter from the hoses and ZERO it relative to ambient pressure before each reading.
