INTRODUCTION
This Sper Scientic Environmental Meter with SD Card
Datalogger (Model 850071) is an extremely fast and
accurate meter with multiple functions. The meter reads
humidity, air temperature, air velocity, and measures

SD Card Data Structure
• The rst time a SD card is used in this meter, a folder
EMA01 will be generated.
• If the datalogger is being used for the rst time, a new
le EMA01001.XLS will be generated under the route
EMA01\.
• After exiting the datalogger and executing the function
again, the data is saved to the EMA01001.XLS le until
the data reach 30,000 data columns. A new le will then
be generated (i.e. EMA01002.XLS).
• The folder EMA01\ will hold 99 les. A new route will be
generated when exceeding 99 les (i.e. EMA02\).
The le’s route structure:

BATTERY REPLACEMENT
This meter uses six AA (1.5V, UM3) batteries. When

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 and hold POWER for 2 seconds to turn the
meter o󰀨.
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 during use (i.e.
the system is frozen and the keypad is non-operational),
reset the meter:
1. 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).
2. Press POWER to turn the meter on.
