3. OPERATION
Before turning the instrument on, connect the SICRAM probes to the inputs: 8-pole male DIN
45326 connectors
, located in the upper part of the instrument.
You can connect the following probes to the inputs:
Input 1
Indoor Air Quality for the SICRAM probes:
•
P37AB147: It measures CO
2
Carbon Dioxide, CO Carbon Monoxide, Relative Humidity
RH, Temperature T, and Atmospheric Pressure Patm.
•
P37B147: It measures CO Carbon Monoxide, Relative Humidity RH, Temperature T, and
Atmospheric Pressure Patm.
•
Humidity and Temperature combined probes.
•
Temperature probes with Pt100 sensor .
Input 2 Temp-Air Velocity for the SICRAM probes:
•
Hot-Wire Sensor Wind Speed probes.
•
Vane Wind Speed probes.
•
Temperature probes with Pt100 sensor .
NOTE:
Connect the probes when the instrument is off. If a new probe is connected and the
instrument is on, it won’t be detected. You need to turn the instrument off and on.
NOTE: If you connect two temperature probes with Pt100 sensor to the two inputs, only the
Indoor Air Quality input probe will be detected. The Temp – Air Velocity input probe will be
ignored.
If a probe is disconnected when the instrument is on, you will get an acoustic signal (one beep per
second) and an indication on the display relevant to the physical quantity being disconnected. The
LOST message will be displayed.
During turning on, the following message is displayed for about 10 seconds:
