Hardware

Air release needle valve is located on the face plate of the DP2000A. In most cases, this would be in the back of the computer. With a screwdriver, turn the valve clockwise to decrease air flow and counter-clockwise to increase air flow. For example, if a measurement takes a total of 40 seconds to release the air, then turn the screw a quarter of a turn or less counter-clockwise. This may take a few measurements until you obtain the range of 25 to 35 seconds.

If the screen displays "pump" and the cuff does not inflate, recheck the hosing and make sure that there are no kinks. If the cuff inflates slightly but not fully, then it may be possible that the cuff has a leak somewhere. Send unit with cuff in for repairs service.( A RMA number msut be obtained). Verify that the pump is engaged when starting the measurement. If the pump is not engaged when it is supposed to, please contact the Technical Support Department.

You must set the jumpers to the specific setting in order for the software to identify it on a particular communication port. Please refer to the following diagram.

Verify that your DynaPulse software is compatible with your computer operating system. V3627 will work in Windows 95, Windows 98, and also with the higher speed Pentium II systems.

Verify that the jumpers are set for the correct communication port you want to use. The default settings are Com 4, IRQ 5. Refer to the Diagram above.

If the comcheck feature under the Options menu identifies the port, but continues to give a communication error message upon measuring, follow these instructions:

In Windows 95 and 98, go to Start/Settings/System/Device Manger/ Ports/ Port Identified(1,2,3, or 4)/Port settings/ Advanced. Remove check mark next to Use FIFO Buffers and click OK. Now go back to the DynaPulse program and run comcheck first. Once it identifies the port, try to take a measurement. If this fails go back to your Advanced Port Settings and replace the check mark next to Use FIFO Buffers. Lower the settings for transmitting and receiving buffers. It should be set at 1 or all the way to the left. Retry measurment.
