4. MEASURING PROCEDURE 4-1 Air Velocity Measurement 1) Power on the instrument by pressing the " Power Button " ( 3-1, Fig. 1 ). 2) Select the Anemometer function by pressing " Function Button " ( 3-6, Fig. 1 ). 3) Press the " Unit/Zero Button " ( 3-4, Fig. 1 ) to select unit that you want and then face the " Air Flow Sensor " ( 3-7, Fig. 1 ) to the source of wind. 4) Allow time for the reading to become stable and note the value indicated. From a practical point of view the velocity may fluctuate.
* The temperature difference between thermocouple probe and thermometer will cause an inaccurate measuring result. Therefore, for the best measuring and accuracy performance, whenever change a probe or plug a new probe, thermal equivalent between probe plug and meter's input socket is a necessary condition. Thermal equivalent procedure may take few minutes and apply only when the probe has been exposed to an ambient temperature different from the meter.
Zero Offset Adjustment of Light Function : * For best results zero the light sensor prior to use in a dark environment. Placing the light sensor end of the meter under a desktop or flat surface so as to block any light can accomplish this. Then press the "Unit/Zero Button" ( 3-4, fig. 1 ) to set the meter indication to zero. * Zero point can drift due to environment temperature and battery power change as well as for other reasons.
2) With the REC symbol on the display : (a) Press the " Max./Min. Button " ( 3-3, Fig. 1 ) once and the " Max " symbol along with the maximum value will appear on the display. (b) Press the " Max./Min. Button " again, the " Min " symbol along with the minimum value will appear on the display. (c) To exit the memory record function, press the " Max./Min. Button " continuously for at least 2 seconds. The display will revert to the current reading. (d) Clear the Max./Min.
7. OPTIONAL TEMPERATURE PROBE AND OTHER ACCESSORIES Thermocouple Probe (Type K) TP-01 * Measuring Range : -40 to 250 ℃ ( -40 to 482 ℉ ) * Max. short-term operating temperature: * It's an ultra fast response naked-bead thermocouple suitable for many general Thermocouple Probe (Type K) TP-02A purpose application. * Measuring Range : -50 to 900 ℃ ( -50 to 1650 ℉ ) Thermocouple Probe * Dimension: 10cm tube, 3.2 mm Dia.
