INTRODUCTION
The Sper Scientic RH/Temperature SD Card Datalogger
(Model 800021) is an extremely accurate meter with fast
response times that reads relative humidity (RH), ambient
temperature, dew point, wet bulb, 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.

SETUP MODE
The advanced Setup Mode allows you to customize the
following meter preferences and defaults:
•Real Time Clock
•Decimal Type
• Auto Power O󰀨
•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 o󰀨 and on again.
Once a selection is saved, the meter automatically advances
to the next setup function (i.e., after setting the real time
clock, the meter will automatically enter the decimal type
setup function).
1. Press POWER to turn the meter on.
2. Press SET for 2 seconds or longer to enter Setup Mode.
3. Press NEXT to cycle through the setup functions.
Note…
Press ESC to exit Setup Mode. The meter will return to
Normal Mode.

SD Card Data Structure
1. The rst time a SD card is used in this meter, a folder
HTA01 will be generated.
2. If the datalogger is being used for the rst time, a new le
HTA01001.XLS will be generated under the route HTA01\.
After exiting the datalogger and executing the function
again, the data is saved to the HTA01001.XLS le until the
data reach 30,000 data columns. A new le will then be
generated (i.e., HTA01002.XLS).

20
3. The folder HTA01\ will hold 99 les. A new route (i.e.,
HTA02\) will be generated when exceeding 99 les.
4. The le’s route structure:
