The temperature display is updated at
approximately 2 times per second during
sustained operation.
Humidity
Noncontact thermometers (IRTs) are not intend-
ed for use in extremely humid or condensing
environments. Condensation on the lens win-
dow will impede the optical performance and
prevent accurate temperature measurements. If
this occurs, allow the window to dry by evapo-
ration or wipe with a soft cloth and resume
measurements.
Emissivity
A noncontact thermometer (IRT) determines
temperature by measuring the emitted energy of
an object. Emissivity (E value) is the measure of
an object’s ability to emit infrared energy.
This noncontact thermometer is specially cali-
brated for high emissivity targets and is preset
to an E value of ~0.97. This setting is the most
advantageous for capturing the emitted energy
from water, oils, shortening, fat, vegetables, as
well as frozen, partially frozen and refrigerated
products in boxes and plastic containers.
Note:
Shiny metal surfaces (such as polished
or stainless steel) have low emissivities and
reflect the energy of their surrounding, resulting
in inaccurate temperature readings. The emis-
sivity of shiny metal surfaces can be enhanced
to provide more accurate readings by covering
the measurement area with masking tape, flat
black paint, or a coating of shorting or oil.
Blackened cooking surfaces such as griddles
and cast iron pans make good targets.
Setting/Changing ºC and ºF
Temperature Scales
The food safety thermometer can display
temperature in either the ºC (Celsius) or ºF
(Fahrenheit) scales. The desired scale is
selected at the time the battery is installed:
Selecting the ºC Scale:
When the battery is connected to the battery
leads the ºC scale indicator shows on the
display for approximately 15 seconds. If the
SET button is not pressed the unit will time out
and default to the ºC or Celsius scale.
Selecting the ºF Scale:
If the SET button is pressed within 15 seconds
of connecting the battery to the battery leads,
the temperature scale display will toggle to the
ºF scale indicator and the unit will now default
to the ºF or Fahrenheit scale
(Figure 14)
.
Note:
The ºC/ºF 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. The unit may be wiped down with a
wet sponge or cloth using a mild water based
detergent or anti-bacterial soap and rinsed
under a gentle stream of cold water
