ECOLOG-PRO 2PTR is a measurement module with two external temperature sensors. Communication from this module with the ECOLOG-PRO RBR is via radio signal. ECOLOG-PRO 2PTR is a measurement module for two external temperature probes (available here). This module requires the communication module ECOLOG-PRO RBR.
External Probe Pt100 4-wire Stainless steel probe L=10 cm, Temperature range -90 °C..+250 °C, Cable length 2.65 m
Second external probe to be bought seperately here.
Make sure that you have defined the sensor's settings in the ELPRO Cloud software and that the "Add sensor" wizard shows the image displayed above. This gives you a 10 minutes time frame to connect your module via the following steps:
Remove the screw on the front and open the measurement module's cover.
Insert the three AA batteries.
Bring the measurement module ECOLOG-PRO 2PTR in close proximity (approximately 10 cm) to an ECOLOG-PRO RBR connected to ELPRO Cloud.
Press and hold the "Connect" button inside the measurement module for more than 3 seconds. The left LED will blink red 3 times.
Wait until the left LED starts flashing red (once per second).
A successful connection will be indicated by the left LED illuminating in green for 10 seconds. Afterwards, the left LED will be flashing green every 10 seconds.
Close the communication module's cover and tighten the screw. Place the module in its intended location (e.g. storage room, next to your ultra-freezer or cryo container, etc.).
