Proper Application and Operation Before You Start First time users should reference “Battery Insertion Replacement” before using the unit.
Noncontact Food Safety Thermometer Proper Application and Operation Note The infrared temperature measurements are used for screening and measuring surface temperatures only. Critical internal temperatures must be verified by using the probe. Mode Selection The SELECT button has two functions. Pressing the SELECT button after the display has gone blank will recall the last display.
FoodPro Plus Users Manual ebq05.eps Figure 3. Extended Contact Probe ebq06.eps Figure 4. Probe Mode Display Notes Remember if the display blanks the select button will recall the last measurement. The probe tip must be sterilized before and between measurements of food samples to avoid cross contamination.
Noncontact Food Safety Thermometer Proper Application and Operation To set the countdown timer, press the SELECT button until the timer icon is displayed (Figure 5). 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.
FoodPro Plus Users Manual • A Green LED indicator shows a safe chilled or frozen condition below 5 °C (41 °F) or a safe holding temperature above 57 °C (135 °F). • The Red LED indicator light is displayed when temperatures are within the HACCP “Danger Zone” of 5 °C to 57 °C (41 °F to 135 °F) where microbe growth occurs most rapidly (Figure 5).
Noncontact Food Safety Thermometer Noncontact Temperature Measurement Applications the product in a refrigerated environment such as a walk-in cooler, either make rapid measurements (within 1 minute or less) or allow 30 minutes for the unit to stabilize in the refrigerated environment (above 0 °C / 32 °F) before measuring. To measure an item within a storage case, open the door or curtain, and directly scan the product for uniform temperatures.
FoodPro Plus Users Manual contents of delicases, chilled salads and desserts, holding ovens, rotisseries, etc. Note If any questionable temperatures are indicated or if temperature readings are within ±1 °C (±2 °F) of the HACCP “Danger Zone” boundary, use the probe to check internal temperatures. Field Verification of Accuracy Infrared (IRT) and Probe channels (RTD) Follow the steps below to verify the accuracy of your food safety thermometer.
Noncontact Food Safety Thermometer Field Verification of Accuracy ebq11.eps Figure 8. Cold Temperature Verification Check The noncontact (IRT) measurement should be within ±1 °C (±2 °F) of the reference probe reading (nominally 0 °C (32 °F)). The probe temperature reading should be within ±0.5 °C (±1 °F) of the reference probe reading. Hot Temperature Verification Check 1. Follow the same procedure as above, substituting hot water (>140 °F/60 °C). Hot tap water is adequate for the procedure. 2.
FoodPro Plus Users Manual ebq12.eps Figure 9. Hot Temperature Verification Check Using this method, the noncontact (IRT) channel should be considered accurately calibrated if the reading is within ±2 °C (±3.5 °F) of the reference probe’s reading; the unit’s probe reading should be within ±0.5 °C (±1 °F) of the reference probe reading. Cautions • Hold the noncontact thermometer outside the rim of the cup, approximately 3 inches from the surface of the water.
Noncontact Food Safety Thermometer Field Verification of Accuracy ebq13.eps Figure 10. Noncontact Thermometer Working Range Operating and Ambient Temperature Range The food safety thermometer is designed to operate in environments between 0 °C – 50 °C (32 °F – 122 °F). Avoid subjecting the unit to extreme or abrupt changes in ambient temperatures. Allow the unit to stabilize for a minimum of 30 minutes if exposed to rapid temperature changes.
FoodPro Plus Users Manual Humidity Noncontact thermometers (IRTs) are not intended for use in extremely humid or condensing environments. Condensation on the lens window will impede the optical performance and prevent accurate temperature measurements. If this occurs, allow the window to dry by evaporation or wipe with a soft cloth and resume measurements. Emissivity A noncontact thermometer (IRT) determines temperature by measuring the emitted energy of an object.
Noncontact Food Safety Thermometer Setting/Changing ºC and ºF Temperature Scales ebq15.eps Figure 12. Setting/Changing °C and °F Temperature Scales Note The °C/°F temperature scale initialization process must be performed whenever battery power is interrupted or the battery is replaced. Cleaning Instructions This food safety thermometer is sealed to IP54 standards.
FoodPro Plus Users Manual Probe Replacement The modular probe of the food safety thermometer is replaceable. To replace probe, extend the probe partially to access the rubber caps. Carefully pry up the rubber caps using a pin, and remove the screws using a #2 cross-tip screwdriver as shown. Grasp the probe and carefully separate the old probe from the probe base. Install the new probe in the reverse order, firmly tightening the screws and replacing the rubber plugs.
Noncontact Food Safety Thermometer Setting/Changing ºC and ºF Temperature Scales Note Each time the battery is installed or replaced, the temperature scale will default to the Celsius scale. To select the Fahrenheit scale see ‘Setting/Changing °C and °F Temperature Scales’.
