Probe Humidity and Temperature Measurements
1. Attach the probe to the meter via the jack at the top of the meter.
2. Hold the probe in the area to be tested & allow adequate time for readings to stabilize.
3. Read the Relative Humidity (center of LCD) and Probe Temperature (top of LCD).
NOTE: Do not immerse the probe in liquid; it is intended for use in air only.
InfraRed (Non-Contact) Temperature Measurements
1. The IR sensor is located at the top of the meter.
2. Point the sensor toward the surface to be measured.
3. Press and hold the large red IR button to begin measuring the surface
temperature of a desired target. IR TEMP and will appear on the
display. The laser pointer will switch on to help aim the meter.
4. The measured IR surface temperature will appear at the center of the
LCD (larger digits). The temperature displayed is the temperature of the
area within the spot.
5. When the red IR button is released, the laser pointer will switch off and
the reading will freeze (data hold) on the display for approx 10 seconds.
6. Note that the probe (Air Temperature wand) continues to monitor
