Note on Thermistor Sensors:
Ensure the
30k9 Load Resistance
is selected in the
Calibration
section of the
Sensor
properties
in the EMS software.
Notes on Accuracy:
Due to the nature of the connections, the onboard Thermistor channels have an
accuracy of +/- 0.5
⁰
C and the Humidity channel has an accuracy of +/-3%.
For greater accuracy, you should use RL4000 or RL5000 radio sensors (+/- 0.2
⁰
C and
+/-% as standard).
Note on Stability:
If the Thermistor or RH channels produce unstable results, fit a 10μF tantalum electrolytic
capacitor across the relevant terminals.
This operation is polarity sensitive, so the capacitors should be fitted as follows:
EMS Sensor Type
Channel Capacitor
Connections
RL2000 Dual Thermistor
Thermistor A
Pin 1: Positive
Pin 2: Negative
Thermistor B
Pin 3: Positive
Pin 4: Negative
