Setup Instructions
1. Open the packaging and remove the miniPEK.
2. Follow the instructions below based on the pressure sensor that has been soldered to the PCB.
LP Series: If you are measuring differential pressure, connect one end of both pieces of tubing to the ports of the pressure sensor 		and the other end of both pieces to the ports of the pressure source that you are testing, e.g., an air duct. If you are measuring 		gauge pressure, connect one end of tubing to the top pressure port and the other end to the pressure source, leaving the bottom 		pressure port open.
HTS Series: Connect one end of tubing to the pressure port and the other end to the pressure source.
3. Connect the USB 2.0 connector to your computer and the Micro-B connector to the miniPEK.
4. Power up your computer, if necessary.
5. Install the free Merit Sensor Evaluation Software.
Note: Windows 10 automatically installs the driver for the Merit Sensor Evaluation Software. The driver can also be installed 			manually by downloading it from the following link: http://ww1.microchip.com/downloads/en/DeviceDoc/MCP2221%20			
Windows%20Driver%202014-10-09.zip.
a. Go to meritsensor.com/products/minipek/ and select the button “Download Software.” A zipped folder named “miniPEK-			software” will become available on your computer.			
b. Save the software to an appropriate drive on your computer.
c. Unzip the software folder.

d. Double-click or right-click on the “setup.exe” file to open it.
e. If you are prompted with any security warnings, it is safe to install or run the software.
f. If your computer prompts you to install the .net framework, which is necessary for the software to function appropriately, do so.		 Note: The framework installation can take a while depending on your internet connection and computer hardware.
g. The application will launch.
6. Once the software is running, select the appropriate miniPEK part (1420 for LP and 1510 for HTS) and the pressure sensor that has 		
been soldered to the PCB from the drop-down menus in the top two fields of the software window.
7. Make any other adjustments to the software settings, as necessary. To learn more about the options, refer to the information below.
