13 Jan 2011 Fisher Science Digital Manometer Serial Driver Reads pressure measurements from a Fisher Science digital manometer Author: Kumar Mallikarjunan Tim

At the suggestion of Matlab staff, here is the very simple change I made to get this code to work with the OEM manometer from AZ Instrument Corp of Taiwan. These are readily available on ebay ('digital manometer' ... look for the distinctive AZ device look, as on the AZ web site).

In line 50, a more generic prefix is substituted for the Fisher device's ...
usertag = ['Serial-' serialCOMPort];

All of the AZ handheld instruments work in the same way. They just use a device type-specific prefix (eg 'P' for pressure (see the parseDataPacket function). The exact syntax is described in each device's RS232 software manual.

Thanks for this. I successfully made v minor mods to your code to allow it to work with the generic manometer from the apparent OEM manufacturer of the Fisher device, AZ Instrument Corp (Taiwan). A minor further mod should allow it to work with all their handheld instruments.
Note that the output rate is limited by the manometer device to 1 sample/second.
