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. Alternatively, manually record 99 readings for
on-screen review or stream data directly to a computer
using the optional software and cables. Each data set
includes temperature, RH, time and date.

20

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:

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. Tighten the screws on the
battery cover to secure to the meter.

TROUBLESHOOTING

If the meter is not functioning properly (i.e., the system is
frozen and the keypad is non-operational), reset the meter:

1. Press POWER to turn the meter on.

2. Use a small tool (such as a disassembled paperclip or a
pin) to press the RESET button (located on the right
side of the meter under the protective black cover).
Wait a few seconds for the meter to restart.

22

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).
