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.
•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.
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).
