OPERATION INSTRUCTION
1.
Connect the t
emperature and measuring signal output
of MDS
-
4 module
to a PC
via a DAQ.
We recommend using the DAQ with analog input resolution at least 14
-bit.
2.
Connect the 3.3
V stabilised DC power supply with the power input
of MDS
-4
module.
3.
Use
the formulas (1) and (2) from p. 4 for signal processing at your PC.
The
calibration coefficients (
a, b, c, d, e, f
) are pointed in the technical report appropriate to
your MDS-
4 module.
Precautions
Turn on the power supply only after all connections are
made and tested.
Do not disassemble the optical
cell; otherwise the optical
system
will be damaged.
Do not use multimeter to control and adjust current
of the LED
.
