- Page 1 Instruction Manual No. 7687-10 Vane Type Thermo-Anemometer Model SK-93F-II No. 3 Nishi-Fukudacho, Kanda, Chiyodaku, Tokyo 101-0037 Japan URL: http://www.sksato.co.jp/english/...
- Page 3 The main unit and sensor probe are fully compatible. When using multiple SK-93F-II units, the measurement accuracy always falls into the acceptable accuracy range even if the main unit or sensor probe of one SK-93F-II unit is combined with the main unit or sensor probe of another SK-93F-II unit. Measurement of air flow By entering/setting the value of the cross-section to be measured, the air flow can be calculated from measured wind speed and displayed.

(2) AC adapter jack Connects the dedicated AC adapter. For details on the AC adapter, see “Using an AC Adapter”. (3) RS-232C cable connection jack Connects the RS-232C cable.
- Page 5 LCD Display Panel (9) 7-segment display (upper part) Displays a wind speed or airflow rate. It displays the entered cross-sectional area in cross-section input mode, or a stored value in data storage mode. (10) 7-segment display (lower part) Displays a temperature value. It displays the number of stored values in data storage mode. (11) Unit of wind speed or air flow Displays “m/s”...
- Page 6 Function Key Panel (A) POWER/RESET key POWER: When this device is off, pressing this key turns the power on. Pressing it again turns the power off. RESET: While in maximum/minimum/mean value measurement mode, pressing this key clears the maximum, minimum, and stored mean values. (B) MODE key This key allows you to select wind speed measurement mode (“VEL”), cross-section input mode (“AREA”), or air flow measurement mode (“FLOW”).
- Page 7 2. Notes on Use To ensure correct use of this device, observe the following items. Because this device is a precision measuring instrument, be careful not to drop it or apply vibration or shock. Do not disassemble or modify this device. Doing so may result in failure. Do not use this device in a place exposed to direct sunlight or near heating equipment.
- Page 8 - Do not dispose of used batteries into a fire. - Be careful not to lose the setscrew of the battery lid when installing a battery. 4. Using the SK-93F-II Measuring Wind Speed (1) Press the POWER key. Numeric values will appear on the display and wind speed measurement mode will be invoked.
- Page 9 the NEXT DIGIT key to save the changed value in each digit. Each time the NEXT DIGIT key is pressed, the cursor moves to the next digit on the right. (5) Set up the cross-section in the same way as in Step (4). The input unit is m (6) After entering the cross-section, press the RECORD key.
- Page 10 “REC” and “AVG” will light on the display panel and the stored mean wind speed and temperature values will be displayed. (8) To clear the maximum, minimum, and mean values, press the POWER key. The device will be turned off and these values will be cleared. Notes: a) It is also possible to record the maximum, minimum, and mean values in airflow rate measurement mode.
- Page 11 Storing Wind Speed or Air flow Data and Displaying the Mean Value It is possible to store wind speed or air flow data in memory and display the mean value. Note: The maximum, minimum, and mean values can also be displayed even during data storage. (1) Press the POWER key.
- Page 12 Auto Power-off If you do not operate the keys for approximately 15 minutes, the auto power-off function will be activated, causing the power to turn off automatically. When continuous measurement is to be performed for more than 15 minutes, cancel the auto power-off function as follows. (1) While holding down the HOLD key, press the POWER key to turn on the power.
- Page 13 9-to-25-pin conversion adapter (available from personal computer stores). Setting the Communication Speed (SK-93F-II Main Unit) (1) While holding down the AVERAGE key, press the POWER key to turn on the power. Make sure that the power has been turned on, then release the POWER key only.
- Page 14 Setting Up the Personal Computer If an RS-232C communication program is to be written in BASIC language, it is necessary to set the communication speed in the personal computer beforehand, as follows. (1) Start the personal computer (2) Enter “SWITCH” at the DOS prompt and press the Enter key. (3) The PC communication environment setup screen will be displayed.
