Overview

The Pressure MAX (PM-1) Digital Pressure Meter is quick to set up, easy to use, and ready to go where you need to be. PM-1 has three ports to measure pressure: a wide port, a narrow port, and a differential port as shown below. The PM-1 can measure air, gas, or liquid (note: liquid measure via wide port only). The PM-1 also has very useful features, such as a Peak Pressure indicator, a built-in Timer, and the ability to set multiple pressure targets. Pressures are displayed in your choice of eleven units of measure, selectable with a press of a button. The Pressure MAX is equipped with Pronk Mobilize™ wireless connectivity.

Batteries and Power
Install the AA batteries in the correct orientation as labeled inside the battery compartment. See figure at right. The PM-1 can also be powered by a standard Pronk 6VDC 2.0 A power supply. When on battery, the PM-1 will shut down if not used for 20 minutes. Battery life is up to 30 hours, depending on the type of battery used. A battery level meter indicator is visible in the upper right side of the display.

Dual Pressure Channels
The PM-1 has two pressure ports. WIDE pressure port is for measuring larger pressure values, -14 to 100 PSI. NARROW pressure port measures lower pressure ranges, -300 to 400 mmHg, and it does so with remarkable accuracy and precision (see PM-1 Specifications). The WIDE port is configured with a bleed screw that enables it to be used with either liquid or gas, while the NARROW port is recommended for use with gasses only. The PM-1 will automatically select which port to display, based upon which port has pressure applied to it. When pressure is applied to a port, the PM-1 will lock the display onto that port and will continue showing only that port for 30 seconds after pressure is released. If no pressure is applied to either port, the PM-1 will toggle the display between the two ports every two seconds so users can see if either port needs zeroing. The NARROW port display will always show an additional digit of resolution over the WIDE port display.

Peak Pressure
The PM-1 captures the peak pressure value and displays it in the top-center of the screen next to the PK icon as shown below. Peak value can be cleared by holding the Timer/ PK button. Peak pressures will also zero when the units setting is changed (see “Selecting Units of Measure,” below).

Timer
Tapping the Timer button will cycle through:

• Timer start
• Timer stop
• Timer reset

Selecting Units of Measure
Tapping the Units/Menu button will rotate through the available units of measure. There are 11 units of measure available: mmHg, PSI, cmH20, atm, mbar(a), mbar(g), bar(a), bar(g), kPa, inHg, inH20.
To filter unneeded units of measure, they can be turned off as follows:

• Hold the Units/Menu button.
• Use the Timer button (scroll UP) or Target button (scroll DOWN) (see image on p. 4) to scroll to the CUSTOMIZE UNITS selection. Tap the Zero/Power button to select.
• Use the Timer button (scroll UP) or Target button (scroll DOWN) (see image on p. 4) to scroll through the units of measure. Use the Zero/Power button to uncheck any unwanted units of measure.
• Tap the Units/Menu button when done.

Thumbscrew Exhaust Port
The Pressure MAX WIDE port can be used for measuring pressure of gas or liquids. When switching between measuring liquids and gasses, it can be useful to remove the fluids from the system before measuring gas pressures and to remove air bubbles before measuring fluid pressures. To remove the liquid or gas from the system:

• Loosen the Thumbscrew Exhaust Port (see figure on p. 4).
• Lay the unit flat.
• Flush the unit with a syringe until no gas or liquid is exiting.
• Tighten the Thumbscrew Exhaust Port. A firm finger tightness is sufficient.

Differential Pressure Readings
Both WIDE and NARROW ports can read gauge pressures. This is the pressure of the port minus current atmospheric pressure. Atmospheric pressure is read via the center ‘Negative Differential Port’ which is normally left open to the air. However, sometimes it is useful to measure the difference between two pressures. For example, when fluid is flowing through an orifice, flow rate can be measured by looking at the pressure difference between the two sides of the orifice. To make these sorts of measurements, the ‘Negative Differential Port’ can be connected to one side of the reading setup, and the WIDE or NARROW port can be connected to the other. In this configuration, the PM-1 will read the pressure difference across the setup. Reading accuracy will be ± 1%, and the range of the negative port is limited to ±1 bar or about ±14 PSI.

Working with Pressure Targets
The Pressure Target feature of the PM-1 gives you a way to check pressure values without needing to see the pressure value on the display. When a target is enabled, the PM-1 will show the target value in the center of the display and:

• If pressure is out of tolerance and below target, the case and display are lit blue.
• If pressure is within a tolerance of the target, the case and display are lit green. If beeping is enabled via the Menu (use the Units/Menu button), unit will also beep slowly.
• If pressure is out of tolerance and above target, the case  and display are lit red.

To enter Target mode or to switch between targets: tap the Target button (see p. 4). To exit Target mode, tap either the Units/Menu button or the Target button when the last target is displayed.

How to Set Pressure Targets
The PM-1 has five programmable Pressure Targets. Each Target has four fields (see figure, right): Target #, Unit of Measure, Target Value, and Target Tolerance.

To edit a target, press and hold the Target button.

1. Select a Target # to edit: initially, “TARGET #1” will be highlighted in blue. To select a different Target # for editing, press to select the Target # field. Then scroll to the desired Target # by using the Timer (= UP) or Target (= DOWN) buttons. Press  again to select that Target #.
2. Select Unit of Measure: after the target # has been selected, use the button to highlight the Unit of Measure (i.e., Units) field. (Note: if a Target # is not currently in use, the Units field will say ‘off.’)  Press to select the Units field for editing. Then use the or button to scroll to the desired Unit of Measure. Then press again to select.
3. Select Target Value: use the button to highlight the Target Value field. Press to select the Target Value field for editing, then use the  or  button to scroll to the desired Target Value. Then press  again to store the Target Value.
4. Select Tolerance: after you have selected the desired Target Value, use the button to highlight the Tolerance field. Press to select the field for editing, then use the  or  button to scroll to the desired Tolerance. Press again to store the Tolerance.
5. Save the Pressure Target: press the Units/Menu button to save this Pressure Target.

Configuring Accessory Hoses
The NARROW port of the PM-1 utilizes a 0.2-inch barrel quick disconnect that is commonly used for NIBP fittings for patient monitors and others. Your PM-1 kit includes a female connector for this, as well as a length of low pressure hose. Because the low-pressure hose is used for the NARROW port, it is easy to manually reconfigure different connectors onto the hose. The WIDE port of the PM-1 utilizes a 5/16 inch barrel quick disconnect fitting which is supported by several manufacturers in different materials and configurations. The accessory fittings supplied by Pronk are CPC PMC series parts, which is a cost-effective, durable Delrin series material of compatible parts which are rated to 120 psi and widely available. A few parts in this series are shown below:

The WIDE port accessory hoses and fittings supplied can be configured in different ways. A high-pressure hose must be used to support the full range of WIDE port pressures, and manually removing this hose from fittings after installation is often not feasible. So, advance planning of the hose configuration is necessary. In the suggestion below, an 18-inch PMC F-F extension hose is built, in addition to several PMC male-based adapter hoses. This configuration has good flexibility and is very cost-effective for building a large library of adapter hoses.

A different configuration could be built to use an M-F extension hose rather than the F-F extension hose. This configuration has the advantage that the adapter hoses can be used directly on the PM-1 without the use of the extension hose, but since the PMC Female parts are roughly four times the cost of the PMC Male parts, it is not as cost-effective for building a large library of different adapter hoses.

Pronk Mobilize Wireless Connectivity
The PM-1 integration of the Pronk Mobilize Wireless Solution provides automated testing and data collection capabilities. Mobilize integration is indicated by “Pressure MAX Mobilize” printed on the device and/or by the part number ending in “-M.”

Fluid Height Units of Measure
Units of Measure that are based on fluid height must be referenced to a specific fluid temperature and value of gravity. The PM-1 references these measures to g= 9.80665m/s2, Water Temp= 4° C, and Mercury Temp = 0° C. These are the most standard modern values, but in some older documents, InHg and InH2O can reference 60° F, which would give slightly different values.

Temperature Range Errors
The PM-1 is only validated to its specified accuracy over its specified temperature range. Beyond this temperature range, it will stop showing pressure and instead show an error message and the measured temperature value. To avoid temperature errors, keep your PM-1 in the passenger compartment when traveling by car or plane, and indoors when possible. To quickly recover from temperature errors, place the PM-1 in an area within temperature specifications (I.E pocket next to your body).
