INTRODUCTION

The Sper Scientific Visible Light SD
Card Datalogger (Model 850007) is
an intelligent meter that reads light in
Lux or Foot Candles 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
light measurement, time and date.

data is saved to the
LXA01001.XLS file until the data
reach 30,000 data columns. A
new file will then be generated
(i.e., LXA01002.XLS).
