Instrument Security

Security options include two different electrical security options that alarms after a user
designated number of temperatures is reached or when the unit is removed from the wall
holder (Model 692 only). A mechanical security option is also available to prevent removal of
the unit from the wall mount or mobile stand without a special tool. The design of the

that are user selectable. Both systems require the use of a holder system with the
thermometer. This setting will be retained in non-volatile memory when the batteries are
replaced.
2.4.1 Temperature Count Security Feature
The Temperature Count security feature allows you to take a set number of temperature
readings before the instrument goes into the security alarm state. The selectable counts are
25, 50, 100, and 200. As the instrument nears the final reading, it will display SECURITY
COUNT as a warning, along with a number representing the last 5 temperature counts (i.e.,
5,4,3,2,1) remaining on the security counter.
When the instrument enters the alarm state, it beeps for approximately 10 seconds. At this
time, the instrument displays SEC on the LCD along with SECURITY COUNT in the ID field in
the upper left-hand corner of the screen. The instrument is then disabled. Returning the
instrument to the wall holder resets the security count. If the count is set to OFF, the
temperature count function is disabled and no security alarm will occur.
This setting is programmable through the Biotech mode (page 11).
2.4.2 Instant-On Security Feature
When the Instant-On security feature is activated, the instrument goes into the security alarm
state within five seconds after removal from the wall holder. When the instrument enters the
alarm state, it beeps continuously and displays SEC on the LCD. Pressing the Mode
