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.
Field of View
The ideal working range of the noncontact thermometer (IRT) is between
25 mm and 250 mm (1 and 10 inches) or the field of view from the target
to the unit, divided by 2. The built in target illumination beam helps to
indicate the measurement area. To ensure accurate measurements, the
measurement target must fill or exceed the field of view. When conditions
permit move in closer to the subject (Figure 10).

Cautions
Hold the noncontact thermometer outside the rim
of the cup, approximately 3 inches from the
surface of the water.
Avoid steam condensation on the unit's lens. If
condensation forms, carefully wipe the lens or let
it dry at room temperature and resume
measurement.
