The IDA 4 Plus computes flow rate by measuring the time it takes to fill a glass tube of known volume. The IDA 4 Plus senses when the measuring tube is filled, then drains the measuring tube, and the cycle begins again. While the measuring tube is being drained, the IDA 4 Plus occludes its inlet. This is the clicking sound the IDA 4 Plus makes.

The RS232 ports (Serial Port) on your computer and IDA 4 Plus must be configured the same way. Hydrograph for Windows assumes the IDA 4 Plus RS232 port to be set to its default: 19,200 baud.

Verify that your IDA 4 Plus RS232 port is set to 19,200 baud. RS232 settings be viewed in the Utilities menu.

If using Hydrograph for Windows, verify that Hydrograph has configured your RS232 port to 19,200 baud. In Hydrograph, RS232 port settings can be viewed and changed, by clicking "Control" on the menu bar, then by selecting the "Com Port Settings" option.

It is very important that no air is present in the pump, bag, syringe or tubing.

Add a single drop (per 100 mL) of dishwashing detergent (Dawn works well) to your water. The detergent is not used as a cleanser, it is used to make the water "slippery". This helps prevent drops that cling to the IDA 4 Plus internal measuring tube.

Use only water. Use of saline or any liquid other than water is not recommended. Use of a liquid other than water can dirty the IDA 4 Plus internal glassware, resulting in poor priming, error messages, or loss of accuracy.

To run Hydrograph for Windows on Windows 98/2000/XT, Hydrograph for Windows Version 2.05 is required.

In order to use the Wedge Adapter, a specific cable must be used to allow the medTester to communicate with the IDA 4 Plus. This cable can be ordered from Fluke Biomedical, part number 2201042.

The syringe must be filled with water, not saline or any other liquid. Inspect the water in the syringe, purge out any air before priming.

When priming, infuse steadily and slowly. This won't slow you down, priming only takes a moment.

There are a number of USB-to-Serial adapters that can be connected to the IDA 4 Plus for communication. We recommend the Digi Edgeport/1 (DB-9) adapter for use with the IDA 4 Plus.

Start the first channel.
Select STATUS to return to the "Status All Channels" screen.
Select the next channel you want to start.
Follow the same start procedure for each channel.

Yes. The number of channels/pumps you can test depends on the number of channels on the IDA-5 or IDA-4 Plus you have available. Ansur has the ability to test up to 16 pumps at once, but in this instance you will need 16 available channels equivalent to four 4-channel IDA-5 units.
