Pre-Setup Requirements
Before starting your study, power on the QUESTemp and check the battery level. The unit requires at least 6.5 Volts to operate reliably throughout a study [00:17].
Step 1: Configuration and Calibration Check
-
General Settings: Enter the Setup tab to select your preferred units (Fahrenheit or Celsius), language, and set the current time and date [00:30].
-
Index Selection: Choose between Heat Index or Humidex depending on your specific reporting requirements [00:52].
-
Reset: To ensure a clean data set, navigate to the Reset option on the main menu and hold the Enter key to clear previous study data [01:25].
-
Calibration Verification: Remove the top sensor bar and plug in the verification module. Compare the displayed values to the numbers printed on the module; if they are within 0.5°C, the instrument is within calibration [01:52].
Step 2: Preparing the Sensors
-
Wet Bulb Maintenance: Check that the wet bulb wick is clean. Fill the reservoir with deionized or distilled water to keep the wick functional and prevent mineral buildup [02:41].
-
Acclimation: Turn the machine on and wait approximately 10 minutes before starting your test. This allows the sensors to reach equilibrium with the surrounding environment [03:07].
Step 3: Running the Study
-
Positioning: Place the QUESTemp in the desired testing area, ideally mounted approximately 3.5 feet off the ground [02:57].
-
Starting: Enter View mode and press the Run/Stop button. A running clock indicates the unit is actively storing data [03:07].
-
Understanding Readings: The unit calculates several values, including:
Step 4: Stopping and Saving
When the monitoring period is complete, press the Run/Stop button to end the test and secure the data in the instrument's memory for download [03:29].
