The TV2 is a highly engineered monitor/alarm/logger with a simple user interface. It uses remote wire or wireless sensors to collect temperature, humidity and/or pressure data. The Easy-Touch™display shows current conditions as well as days, weeks, months and even years of logged data. It complies with all federal regulations.
It displays current, maximum /minimum conditions and digital charts for up to four remote wired or wireless sensors. It logs and charts all monitored conditions which it stores in non-volatile memory for protection. All stored data is encrypted to comply with intent of the 21 CFR 11 standard, and can be copied to a computer for archiving or printing with a USB cable or over a Local Area Network. All logged data can be viewed in graphic form or exported to an Excel file.
Logged (stored) data:
The TV2 stores up to 80,000 data points for each sensor, which means that it will store over 2 years of temperature history if you are sampling temperature once every 10 minutes. If you are logging temperature and humidity, it stores over 12 months of history for each of the four sensors. Although the TV2 can store and display temperature from absolute zero to thousands of degrees, the actual temperatures collected depends on the type of sensors being used (see below).
In addition to showing the current conditions the TV2 can display the logged data for each sensor. Touching one of the displayed values on the QuickCheck display causes the logged data to be displayed as an easy-to-read chart. The chart can be scrolled backwards and forward. It can also be zoomed into or out of to show more or less data.
The menu system
A password-protected Easy-Touch menu is used to set the system and display parameters such as high and low temperatures, sampling intervals, and alarm levels. Since the menu system is password protected, the TV2 can be placed in high traffic areas so that each staff member can see it and be part of your quality control process.
The TV2 is powered with wall power or through a USB cable and has a internal 72-hour rechargeable lithium battery backup. When it enters battery mode during a power failure the display ‘sleeps’ but the sensors continue to collect data for over seventy-two hours depending on your settings. In the event that power is not restored before the battery is depleted, the stored data will still be retained although the unit will no longer log or display new data. Once power is restored, the display wakes up, the battery begins to be recharged, and normal operations continue.
The TV2 display:
The LCD is a full color Easy-Touch graphic display, controlled by a
microprocessor that updates ever few seconds to show real-time data so everyone knows what is going on all the time. I can display temperature, humidity and pressure information depending on which sensors you have plugged into the display. Any time any of the displayed vales becomes unsafe it turns red, so training personnel is as simple as telling them that any time they see red on the display they should call maintenance.
The bottom of the QuickCheck display shows the current date, and time, the battery charge level, a network connected icon, as well as the Menu and Last Reviewed Date hot-spots.
