TARE selection
It is not unusual that, under normal operating conditions, the zero setting on the MicroFID II may
drift below zero. To readjust the display to zero, press the TARE key, and the display will be re-
set at 0.0.
4. WIRELESS COMMUNICATION
The MicroFID II uses a Bluetooth communication chip as the means to download and upload
information to and from the MicroFID II memory. The users must be sure that the Bluetooth
communication device software and Bluetooth device are running, paired and active when trying
to communicate with the MicroFID II.
NOTE: When the unit has been powered off, the computer or PDA must reinitiate
communication with the Bluetooth chip in the MicroFID II. This must be done each time the unit
has been powered off.
Wireless Communication Range
Most Bluetooth devices are capable of transmission approximately 30 feet away from the
send/receive device (in this case the computer or PDA to the MicroFID II and vice versa). Users
should be aware that the signals sent from the MicroFID II and the computer/ PDA are not
capable of transmissions through such items as steel doors and floors which disperse and block
the transmission signal. Most manufacturers will provide some sort of signal strength meter
within their software that will advise the user if a communications link between the receiving
device and the sending device is functioning and, in some cases, the signal strength.
Pairing
Bluetooth-enabled instruments need to be paired with the receiving or sending base which is
typically a computer or PDA. The pairing protocol will create a communications port for the
computer linking device, and will then begin a search for Bluetooth serial communications
devices. This pairing will occur during a send receive from the unit setup within the
computer/PDA when the user selects a specific device serial number from within the MicroFID II
unit. Most software programs from Bluetooth-enabled devices will find available MicroFID II
units with the sending unit. This serial number will not be the INFICON MicroFID II serial
number which is etched into the casing but rather the serial number of the Bluetooth
send/receive chip within the MicroFID II. For instance, MicroFID II unit serial number AZ300505
has a Bluetooth chip within it having the serial number ending in: C001. Users should rename
and add in the MicroFID II serial number to the information for the Bluetooth serial number as to
not confuse the data transmission and download or upload from other units accessing the
Bluetooth software program.
