Probe Mode
To measure the internal temperature of an
object, extend the probe
(see Figure 4)
and
press the MODE button until the Probe Icon is
displayed
(see Figure 5)
. Insert the probe at
least 1/2" (12mm) into the target and press the
ON button to measure the core temperature.
The Probe Icon on the display will blink for
approximately 15 seconds as the probe comes
to equilibrium with the object being measured.
Three short beeps will sound to indicate the
reading is complete and the temperature will be
shown on the display. When the highest accu-
racy is required, it is advisable to repeat the
measurement cycle to insure the probe has fully
stabilized and reached equilibrium with the
object.
Note:
Remember if the display blanks the
mode button will recall the last measurement.
Note:
The probe tip must be sterilized before
and between measurements of food samples to
avoid cross contamination.
Countdown (Timer) Mode
The food safety thermometer has a built in
countdown timer to conveniently monitor cook-
ing, cooling, and critical exposure times, as
well as Hazard Analysis Critical Control Points
(HACCP) inspection intervals. HACCP princi-
ples and good food safety practices require
monitoring the length of time perishable foods
are exposed to temperatures that may support
12mm min

To set the countdown timer, press the MODE
button until the timer icon is displayed
(Figure
6)
. Press the SET button once to enter the set
mode (“SET” on display blinks). Press the SET
button a second time to clear and increment the
timer value. The timer value increases initially
by 10 second intervals then by minutes and
hours. The timer can be set for a maximum of 7
hours and 59 minutes.
Once the desired timer value is set, pressing
the ON button will start and stop the count-
down. An alarm will sound for approximately
30 seconds when the timer reaches zero.
Note:
The timer can be activated and running
in the background (indicated by the flashing
timer icon) during either IR or Probe measure-
ments or when the display is off. Pressing any
button will silence the sounding alarm.
To clear the displayed timer value, press the
SET button once to enter set mode and a
second time to zero the timer value.
HACCP Check
This thermometer incorporates a “HACCP
Check” feature to graphically display critical
temperature zones. The icons and LED indica-
tors located above the display indicate a food
product is safely held at a sufficient holding
temperature, or if it has fallen within the unsafe
HACCP “Danger Zone” temperatures.
