The SDMN5 is capable of taking gas pressure as well as static pressure. The SDMN5 comes in a rugged rubber boot. The SDMN5 also has a zero adjust and a hold button to hold the cur- rently displayed reading. The auto-power-off func- tion conserves battery life, but can be disabled if desired. The SDMN5 will allow you to take gas pressure up to ±60” (152cm) of WC. The SDMN5 will take dif- ferential pressure readings and display the differ- ence between P1 and P2 at all times in the lower right corner of the LCD. The SDMN5 also has four different measurement scales including inches of water column, millimeters of water column, mBar and PSI. Static pressure is possible with the reso- lution to 0.01” of WC (0.1mmWC). Special purpose static pressure instruments are on the market with better accuracy and temperature compensation but they typically cost many times more than the SDMN5. Operation 1. Zero the SDMN5 by pressing the ZERO button just before taking the pressure readings, while at ambient pressure. This will zero both P1 and P2. 2. Connect a single hose to get the gauge pres- sure relative to the ambient or ZERO pressure. 3. Connect both hoses if you want to see relative pressure, P1 minus P2. 4. By pressing the P1 / P2 button you can change between displaying P1 or P2, P1 - P2 is con- stantly displayed in the lower right of the LCD. 5. Pressing the unit button makes it possible to switch between the four measurement scales of inches of water column (inWC), millimeters of water column (mmWC), mBar, and PSI. The scale being viewed is displayed on the right side of the LCD. 6. To disable the auto-power-off hold the HOLD button while turning the unit on. If the auto- power-off is enabled (meter will turn off automat- ically) an APO will appear on the display. If Auto-power-off is disabled (meter will not turn off on its own), then no designation will appear on the LCD. 7. If you are in an environment where the tempera- ture is noticeably changing while you are taking your reading, it is advised that you disconnect the meter from the hoses and ZERO it relative to ambient before each reading. Checking Gas Pressure on a Regulator 1. Screw the brass fitting into the pressure port on the regulator. 2. Put unit into operation (i.e. turn on the furnace and have furnace ignite, as if running it in nor- mal operation.) 3. This will give you the pressure coming out of the regulator. 4. If you suspect high or low inlet pressure into the regulator, the manometer can hook into the inlet port in the same manner it can connect into the outlet port. If you have a dual-port manometer, you can check both the inlet and the outlet simultaneously and see the pressure drop across the regulator. 5. See manufacturer's specification for the specifi- cations on target inlet and outlet pressure for a given regulator or piece of combustion equip- ment. Battery Check Function Press and hold the UNIT button to display the percentage of usable battery remaining. This function can be used any time the meter on. Field Calibration Pressure: By pressing the ZERO button, both the P1 and P2 are zeroed to the pressure they are being exposed to. For this reason the calibration should be done when both P1 and P2 are dis- connected from the hoses.

1. Connect ASP2 to SDMN5 via hose.2. Insert ASP2 into drilled or pre-existing 1/4” hole.3. Use allignment arrow on the ASP2 to direct probe
into the air stream.4. Read static pressure measurements from the dis-
play on the SDMN55. Remove probe and patch hole.

Modular ExpandabilityModular expandability is ability for accessory
heads and meters to change configurations tomatch the various needs of an HVAC/R technician.
Accessory heads (the sensors) send out a mVsignal, which represents the value of the measure-ment, to whatever meter is attached to it. Heads canattach directly to the top of a Stick meter, DL3 datalogger, or EHDL1. They can also plug into any meterwith mV ranges using ASLS2 leads.
Stick MeterThis is the heart of modular expandability. In addi-
tion to being a full functioning multimeter, any acces-sory head can be used with it.

Accessory HeadsAccessory heads are the sensors of multiple
parameters measured by technicians every day.They plug into a mV range (depending on the head)of a multimeter. The multimeter will display whatev-er the head is measuring. Instead of having to pur-chase and carry a separate instrument for eachparameter, a technician can use multiple heads anda single multimeter to do the job.
