How to use
Power the Unit UT333 using the appropriate battery and allow the sensor to stabilize in the measurement environment for a short period. Hold the handheld meter in the area where you want to measure ambient conditions, avoid obstructing the sensor, and wait until the displayed values settle. Read the temperature and relative humidity directly from the display. For consecutive measurements, move the unit to each location and allow a brief stabilization time before recording values.
