  • Page 2 Beware of explosion! The SK-28V is not explosion-proof. Never use it in an atmosphere containing flammable gases. * If there is anything you are not unclear about using the SK-28V, please contact our retailer or our service network Descriptions Adopting the principle of thermal anemometer, this product can measure wide range of air velocity.

  • Page 4: How To Use

    How to Use ⚫ Loading batteries (1) Place the Function Switch in Power-Off position. (2) Take the main unit out of the carrying case and load six “C” size alkali batteries (LR14) in the battery compartment located at the back of the unit. Make sure to load them with correct polarities.
  • Page 5 Heat-running and zero point adjustment (1) Place the Function Switch to either of Air Velocity or Static Pressure position. Then put the sensor cap on the probe and run the heat for more than 5 minutes. The pointer will gradually return to zero point from left (minus).
  • Page 6 ⚫ How to measure temperature Place the Function Switch in Temperature position for temperature measurement. Right after measuring air velocity and static pressure, the temperature of the sensor itself is about 100°C higher than ambient temperature. Start to measure temperature after full stabilization (it takes at least 2 minutes) for accurate measurement.
  • Page 7: Cautions In Operation

    ⚫ Caution in general (1) Never put sensor probe into liquid. (2) The SK-28V is calibrated in normal ambient. If the component of air is extremely different from the normal ambient, an error may arise in the measured value. (3) Never touch the sensor until it cools down when measurement was made in 50°C or higher state.
