Introduction VFC400-USB User Guide 6
Introduction
The Control Solutions VFC400-USB Vaccine temperature monitoring Data Logger
features a display, USB connectivity, data logging memory storing up to 16065
temperature readings per channel and a separate statistical memory, storing maximum
and minimum reading as well as alarm duration for each of the last 30 days.
During recording the display shows the following, alternating for each channel:
lThe current temperature (of the most recent reading)
lThe alarm status (within or outside the acceptance range)
lAn alarm trigger summary of up to the last 30 days (today and 29 days previous)
lThe current time and battery status
lMinimum and maximum temperatures since the start of the trip
Alarm events can be triggered when a number of readings are outside pre-set
temperature thresholds, and a “day alarm indicator” appears on the display.
Logged temperature data can be viewed on any PC by plugging the unit into a
computer’s USB port via a micro-USB cable. A PDF file is generated, which can be
accessed using free PDF software such as Acrobat Reader. The VFC400-USB can also be
downloaded to the free companion software Control Solutions VTMC, where you can
display data in chart, list or summary formats. The software also allows electronic
archiving and exporting to Control Solution Web Base VTMC (Vaccine Temperature
Monitoring Cloud) for managing your region/clinical storage & handling needs.

alarm events have occurred for the current day and up to 29 days in the past. Details of
any alarm event can be checked by inspecting the statistics history on the logger's
display or in more detail via Control Solutions VTMC. In addition, a red Alarm LED
shows if an alarm event has occurred.
External Probes
The VFC400-USB will accept external probes from the ST100 product range.
Power Supply
The same USB socket that is used for communication is also used for providing power to
the VFC400-USB, using an external 5V USB power supply. The AAA batteries maintain
all functionality when USB power is not connected. A long-life CR2032 lithium backup
battery maintains essential functions if the AAA batteries are empty and external power
is not supplied.
PDF
The VFC400-USB will generate a detailed PDFreport when plugged into a USB port of a
PC. The PDF report shows a summary of the trip, presents the data in chart and list
format and also includes a day summary page, showing an overview of the statistics
collected. A CSV file of the data list is also available.
