User Manual EE850 Duct Sensor
MODEL EE850-M10:
Select the CO
2
output signal:
The output signal can be changed from voltage to current or vice-versa.
Set the output signal selection switch to I for current 4 - 20 mA output or to U for voltage 0 - 10 V output.
The original CO
2
output range does not change and the calibration data remains valid.
Model EE850-M10
Example:
Factory setup: voltage output (U), output scale: 0 - 10 V = 0...5000 ppm
User setup (after setting the output signal selection switch to I): current output (I), output scale: 4 - 20
mA = 0...5000 ppm.
MODELS EE850-M11 and EE850-M12:
Changing the CO
2
and T output scale:
The scaling of the output can be changed by using USB Configuration Adapter (HA011066) and Product
Configuration Software (EE-PCS).
Example:
The initial scaling of the outputs is:
The output scale after the change is:
CO
2
: 0 - 10 V = 0...5000 ppm
CO
2
: 0 - 10 V = 400...4000 ppm
T:
0 - 10 V = 0...50 °C
T:
0 - 10 V = 40...100 °F
RH:
0 - 10 V = 0...100 % RH
Td:
0 - 10 V = -20...40 °C
Please note:
After changing the factory setup (output signal and/or output scale) the original type number on the
EE850 identification label loses its validity; it does not match any longer the device setup.
The return to factory setup function of EE-PCS restores the original adjustment/calibration of the
device, but does not affect the user setup for output signal and output scale.
