Micromanometer

The micromanometer is a multifunction instrument useful in obtaining air velocity, air flow, absolute and differential pressure, temperature, and humidity measurements when used with the tools listed below. The lightweight micromanometer incorporates auto-zeroing for high-accuracy, low-end pressure measurements.

Standard Tools

This section gives a brief description of standard tools for the micromanometer.

Pitot Tube

The pitot tube is primarily used to obtain air velocity, air volume, and velocity pressure measurements within ductwork.

Static Pressure Probe

The static pressure probe is primarily used to obtain static pressure measurements within ductwork.

Optional Tools

This section gives a brief description of optional tools for the micromanometer.

Capture Hoods

Capture hoods are primarily used to obtain volumetric air flow measurements through diffusers, registers and grilles. Capture hoods are available in a kit with one 2 ft × 2 ft (610 mm × 610 mm) fabric hood, frame, and base assembly. Alternate hood sizes are available and descriptions and part numbers can be found in

Table 2 of Chapter 2 in this manual.

Velocity Matrix

The velocity matrix is primarily used to obtain area-averaged multi-point air velocity measurements useful in laboratory hood face velocity testing, filter face velocity testing, and other applications.

Air Flow Probe

The air flow probe is primarily used to obtain single point air velocity or air volume measurements in ductwork.

Temperature Probe

The temperature probe is used to obtain temperature measurements over the range of -40 to 250°F (-40 to 121°C).

Temperature/Humidity Probe

The temperature/humidity probe is used to obtain temperature measurements over the range of 14 to 140°F (-10 to 60°C), humidity measurements over the range of 0 to 95% RH, along with calculated wet bulb temperature of 40 to 140°F (4 to 60°C) and dewpoint temperature of 5 to 120°F (-15 to 49°C).

Preparing the Instrument for Use

Before you can use the micromanometer, you must decide on a power source.

Power the Micromanometer with the AC Adapter

When the AC adapter is plugged into the micromanometer, the unit automatically turns on, runs a brief diagnostic check, and briefly lights all segments of the display. It then displays the type of batteries the unit is set to use (alkaline or rechargeable NiMH) and turns itself OFF.

Whenever the AC adapter is plugged into the micromanometer, the rechargeable batteries are recharged. (Assuming you are using rechargeable batteries and the switch inside the battery compartment is set to NiMH. See below.)

Power the Micromanometer with Batteries

When not using the AC adapter, the micromanometer requires four AA-size batteries to operate. These can be either alkaline batteries or rechargeable NiMH batteries. For your convenience, four NiMH batteries are included with the micromanometer.

To select the type of batteries you are using:

1. Turn the unit off and locate the battery cover on the back of the micromanometer (see Figure 4).

6 Model 8710 DP-CALCTM Micromanometer and Model 8375 ACCUBALANCE® Air Balancing Tool

Figure 4: Battery Cover Removal

Press down on the compartment cover and slide it down. (The cover slides off.)

3. Remove the battery holder by pulling up on the bottom (to loosen it) and then pulling the battery

holder free.

4. Refer to Figure 5 and set the battery selection switch to indicate the type of batteries you are using.

Battery Selection Switch

Figure 5: Location of Battery Type Selector Switch

5. Reinstall the battery holder and replace the battery compartment cover.

To install replacement batteries:

1. Turn the unit off and locate the battery cover on the back of the micromanometer (see Figure 4).

2. Press down on the compartment cover and slide it down. (The cover slides off.)

3. Remove the battery holder by pulling up on the bottom (to loosen it) and then remove the battery

holder.

Chapter 2: Unpacking and Setting Up 7

4. Remove the old batteries and replace with fresh batteries (alkaline or rechargeable NiMH). Make

certain batteries are correctly oriented.

5. Verify the battery selection switch is correctly set (see Figure 5).

6. Reinstall the battery holder and replace the compartment cover.

Note: Make sure the battery holder is oriented so that its terminals make contact with the spring

contacts in the battery compartment.

If fresh, new alkaline batteries are used, the battery indicator will show 4 bars when first turned on. With NiMH batteries, the indicator may show a lower value even when they are fully charged.

Notes: The percent power remaining will not be accurate for NiMH batteries because their voltage

does not decrease linearly with power use.

Due to the danger of battery leakage, remove batteries from the battery compartment before storage. Never mix battery types.

The NiMH batteries should only be charged at room temperature. Starting with batteries that are too cold or too warm can cause the charge cycle to stop early.

Connecting the Pitot Tube to the Micromanometer

The static pressure port (-) on the pitot tube will be connected to the negative pressure (-) port on the micromanometer, and the total pressure port (+) on the pitot tube will be connected to the positive (+) port on the micromanometer (see

Total Pressure Port (+)

Figure 6).

Attaching the Micromanometer to the Capture Hood Base

1. Tilt the meter forward and align the tabs in the base of the meter with the two matching slots in the

bottom of the recessed area at the front of the base (see

2. When the tabs are engaged in the slots, press firmly on the face of the meter above the display until

the tab in the top center of the meter “clicks” into the bent metal retaining clip in the base.

Figure 8).

3. Attach the temperature cable and the back pressure flap switch cable to the right side of the meter.

4. To remove the meter from the base, first disconnect the temperature cable and the back pressure flap

switch cable, then press upward on the metal retaining clip to release the meter from the base.

Figure 8: Attaching the Meter to the Capture Hood Base

Connecting the Velocity Matrix to the Micromanometer

The positive port (+) is located on the side of the Velocity Matrix that is opposite the handle assembly. The positive port (+) on the Velocity Matrix will be connected to the (+) port on the micromanometer, and the negative port (-) on the Velocity Matrix is connected to the (-) port on the micromanometer.

Chapter 2: Unpacking and Setting Up 9

Standoffs can be screwed together to make different lengths and are used to maintain a fixed and level orientation away from a filter. The standoffs are attached to the positive (+) side of the velocity matrix.

The handle assembly is attached to the downstream or negative (-) side in the center of the velocity matrix

Connecting the Air Flow Probe to the Micromanometer

The static pressure port (-) on the Air Flow Probe will be connected to the negative pressure (-) port on the micromanometer, and the total pressure port (+) on the Air Flow Probe will be connected to the positive (+) port on the micromanometer (see

Figure 10).

Note: Observe the arrow indicator on the Air Flow Probe when taking air velocity or air volume

measurements.

Connecting the Temperature Probe or Temperature and Humidity Probe to the Micromanometer

The Temperature probe and Temperature/Humidity probe attach to the 8-pin connector located on the right hand side of the micromanometer. When connecting the probe to the meter, the dimple on the connector must be aligned to fit the receptacle indentation on the meter (see

Figure 11).
