F. Spirometer Handle
There are different versions of the Spirometer handle available.
Midmark Diagnostics Group offers USB and COM port versions of the handle. The USB
handle is designed to operate with a computer.
There are two versions of the COM port handle (COM port handles have a DB9 female
connector). One version is designed to operate with a Pocket PC device (like a
Compaq/HP iPAQ) and the other version is designed to operate with a computer.
The model/serial number is listed on the label on the top of the Spirometer handle (under
the DPM). This should be used to identify the version of the handle.
The model/serial number defines the handle as follows:
03xxx COM port handle for use with a desktop or laptop computer
50xxxx COM port handle for use with a desktop or laptop computer
51xxxx COM port handle for use with a Pocket PC, hand-held device
52xxxx USB port handle for use with a desktop or laptop computer
 NOTE: 51xxxx handles are switched on when the DPM is in place. To
conserve the life of your batteries, be sure to remove the DPM after
calibration or testing. In addition, place the DPM in the handle
BEFORE entering the test or calibration screen. This will turn the
handle on and allow the software to detect the handle.
Please contact Midmark Diagnostics Group Customer Service at 800-624-8950, if you
have any questions about which handle you have.
