MadgeTech Vaccine Temperature Monitoring System (VTMS) Data Logger - Manual (Page 4)

Product User Guide
Product Overview
MadgeTechs Vaccine Temperature Monitoring System (VTMS) is ideal for the continuous
measurement and data logging of temperature sensitive vaccines or pharmaceuticals in
refrigerators, freezers, and coolers. The system includes a NIST traceable RFTCTemp2000A
data logger with thermocouple, Glycol bottle and a power supply. Additionally, the
RFTCTemp2000A data logger in the VTMS system has a convenient LCD to ensure
temperature parameters are met, in real time. The current reading, minimum, maximum
and average statistics can all be obtained through the display.
In the real-time chart recording mode the VTMS can alert the user, or other personnel,
via e-mail or text message if the refrigerator has failed, or if the temperature is outside of
the nominal range. This allows users to take immediate actions to ensure vaccines and
pharmaceuticals in storage are not destroyed. To prevent false alarms, the RFTCTemp2000A
is connected to a Glycol bottle which provides temperature buffered readings.
Selection Buttons
The logger is designed with 3 direct selection buttons: Scroll, Units and Wireless.
• Scroll: Allows user to scroll through current readings, average stats and device status
information displayed on the LCD Screen.
• Units: Allows user to change displayed units of measurement to either °F or °C.
• Wireless: Push and hold this button for 5 seconds to activate or deactivate wireless
communication.
• Manual Reset Option: Allows user to manually reset the statistics within the device to 0
without needing to use the MadgeTech software. Any data recorded up to that point is
recorded and saved. To apply the manual reset, press and hold the scroll key down for
three seconds.
LED Indicators
• Status: Green LED blinks every 5 seconds to indicate unit is logging.
• Wireless: Blue LED blinks every 15 seconds to indicate unit is operating in wireless mode.
• Alarm: Red LED blinks every 1 second to indicate an alarm condition.
Remote Thermocouple Channel
A female subminiature (SMP) or pluggable screw terminal is located on the bottom of the
logger to connect a thermocouple. The RFTCTemp2000A will accept thermocouple types
J, K, T, E, R, S, B, or N.
Wiring the Thermocouple
For MP Model:
Warning: Note the polarity instructions. Do not attach wires to the wrong terminals.
