INTRODUCTION The Sper Scientific Anemometer SD Card Datalogger (Model 850023) is an extremely accurate meter with fast response times that reads air temperature and velocity, and functions as a Type K/J thermocouple thermometer. This meter features a real time SD memory card datalogger. Standard, portable SD memory cards provide unlimited data storage and upload pre-formatted data directly to Excel, eliminating the need for cables or software.
FEATURES • Reads air velocity and temperature and functions as a Type K/J thermometer • Low-friction ball vane wheels provide high accuracy in high and low velocities • SD memory card datalogger • Manual datalogger option • Fast response time for air temperature • Highly accurate microcomputer circuit • RS232 or USB PC connection • Direct upload of data to Excel • Detachable probe for measuring flexibility • Internal clock and calendar • Touch-tone • Tripod mounting screw • Built-in
MATERIALS SUPPLIED • Meter • Probe • SD Card • 6 AA Batteries • Instruction Manual • Soft Carrying Case 6
POWER SUPPLY This meter can be powered by six AA (1.5 V, UM3) batteries or an optional 9 Volt DC adapter. See page 22 for battery replacement instructions. Plug the adaptor into the power port labeled “DC 9V,” located on the side of the meter. Note) When using the adapter to run the meter, the meter will remain permanently on and the POWER button will be disabled.

SETUP MODE The advanced Setup Mode allows you to customize the following meter preferences and defaults: • Real Time Clock • Decimal Type • Auto Power Off • Touch-Tone • Thermometer Type K/J • Temperature Units • Sampling Time • SD Memory Card Format Note) The setup functions can be performed under any parameter but not while utilizing the datalogger function. Once selections are saved, the meter will default to the selected preferences when the meter is turned off and on again.
SETUP MODE Note) Press ESC to exit Setup Mode. The meter will return to Normal Mode. Real Time Clock 1. Enter the clock function from Setup Mode (see page 11). “dAtE” appears on the LCD. 2. Press ENTER. The year will appear on the LCD. 3. Press ▲ or ▼ to adjust the value. Press ENTER to save the value. 4. Repeat Step 3 to adjust the month, date, hour, minute and second. Note) This procedure adjusts the meter’s internal clock.
SETUP MODE 2. Press ▲ or ▼ to select Basic (.) or Euro (,). Press ENTER to save the selection. Auto Power Off The meter automatically turns off after 10 minutes of inactivity, however this function can be disabled. 1. Enter the auto power off function from Setup Mode (see page 11). “PoFF” appears on the LCD. 2. Press ▲ or ▼ to select yes (auto power off enabled) or no (auto power off disabled). Press ENTER to save the selection. Touch-Tone 1. Enter the touch-tone function from Setup Mode (see page 11).
SETUP MODE (see page 11). “t-CF” appears on the LCD. 2. Press ▲ or ▼ to select C (degrees Celcius) or F (degrees Farhenheit). Press ENTER to save the selection. Sampling Time The sampling time is the time allotted between successive measurements. To adjust the sampling time (in seconds): 1. Enter the sampling time function from Setup Mode (see page 11). “SP-t” appears on the LCD. 2. Press ▲ or ▼ to adjust the value (0, 1, 2, 5, 10, 30, 60, 120, 300, 600, 800, 1800, 3600 seconds).
MEASUREMENT PROCEDURES Turning the Unit On/Off 1. Press POWER to turn the meter on. 2. Press and hold POWER for 2 seconds to turn the meter off. Selecting the Function 1. Press and hold FUNC to cycle through the options listed below. Release FUNC when you reach the desired function. • Air velocity/temperature “An” appears on the LCD. • Type K/J thermometer “tP” appears on the LCD. Note) The meter will default to the last function setting used when it is turned off and on again.
MEASUREMENT PROCEDURES Air Velocity and Air Temperature 1. Press POWER to turn the meter on. 2. Plug the anemometer probe plug into the anemometer probe input socket. 3. Press and hold FUNC to cycle through the options until “An” appears on the LCD. Release the FUNC button. 4. Hold the probe handle and point the probe head toward the air flow. The air velocity value appears on the upper display and the air temperature value appears on the lower display.
MEASUREMENT PROCEDURES 5. “K” or “J” appear on the LCD to indicate the type of thermometer. Note) When using the meter for the first time, the meter will default to K type thermocouple. See page 13 for instructions on selecting the thermocouple type. Hold Function 1. When measuring any parameter, press HOLD to freeze the reading on the display. “HOLD” will appear on the LCD. 2. Press HOLD again to release the hold function. “HOLD” will disappear from the LCD.
MEASUREMENT PROCEDURES 5. To exit the min/max function, press and hold REC for 2 seconds or longer. The meter will return to Normal Mode. Note) The meter cannot be turned off from the memory record function. Exit the function, then press and hold POWER to turn the meter off. Backlight 1. The backlight turns on automatically when the meter is turned on. 2. Press to turn the backlight off. 3. Press to turn the backlight on.
DATALOGGER Preparing the Datalogger 1. Insert the SD card into the SD card socket on the bottom of the meter, ensuring that the front of the SD card faces the back of the meter. 2. Format the SD card as needed (see page 14). 3. Set the real time clock if using the meter for the first time (see page 12). 4. Set the decimal type if using the meter for the first time (see page 12.) Auto Datalogging 1. Set the sampling time to ≥ 1 second. Refer to page 14. 2. Press REC. “REC” will appear on the LCD. 3.
DATALOGGER Note) To enable/disable the touch-tone feature, see page 13. Manual Datalogging 1. Set the sampling time to 0 seconds. Refer to page 14. 2. Press REC. “REC will appear on the LCD. 3. Press LOGGER. “REC” will flash on the LCD and the alarm will sound while the measurement data and time information are saved to memory. The position (location) number will appear on the bottom of the LCD and will also be recorded on the SD card. Note) To enable/disable the touch-tone feature, see page 13.
DATALOGGER 2. If the datalogger is being used for the first time, a new file AMA01001.XLS will be generated under the route AMA01\. After exiting the datalogger and executing the function again, the data is saved to the AMA01001.XLS file until the data reach 30,000 data columns. A new file will then be generated (i.e., AMA01002.XLS). 3. The folder AMA01\ will hold 99 files. A new route (i.e., AMA02\) will be generated when exceeding 99 files. 4. The file’s route structure: AMA01\ AMA01001.XLS AMA01002.
BATTERY REPLACEMENT This meter uses six AA (1.5 V, UM3) batteries. When the low battery indicator appears on the LCD, battery replacement is needed. After the icon appears on the LCD, in-spec measurement can still be made for several hours before becoming inaccurate. 1. Press POWER to turn the meter off. 2. Unscrew the battery cover and remove from the meter. 3. Remove the old batteries and replace with six new AA batteries, ensuring correct polarity. 4. Replace the battery cover.
PC CONNECTION To save data from the SD card to a PC (using Excel software): 1. After datalogging is complete, remove the SD card from the meter’s SD card socket. 2. Insert the SD card into the computer’s SD card slot (if built into the computer) or into a SD card adapter (ensuring that the adapter is connected to the computer). 3. Turn the computer on and run the Excel program. 4. Download the saved data file (i.e., AMA01001.XLS, AMA01002.XLS) from the SD card to the computer.
