Appendix 2 - Troubleshooting
If you are having difficulties with your configuration, refer to
the frequently asked questions before contacting technical
support.
I swapped a sensor and received a Sensor Fail error.
But then everything seemed OK. What happened?
Most likely, you performed the swap as the sensor was being
read by the device. This generates an alarm concerning that
precise moment. If the new sensor is working correctly, the
problem can be considered as being very temporary and you
can simply acknowledge the alarm to close it.
The Smart-Vue Pro Duo/Quatro data logger screen is
black. When I tap the screen, nothing is displayed and
there does not seem to be any reaction. What should I
do?
Is your data logger running on battery only?
If so, the batteries might be low and the screen is turned off
because the data logger is in power saving mode. Try
plugging in the AC (USB) power supply. If the screen comes
back on then install fresh batteries (i.e. one after the other)
and/or leave it plugged in.
Are the batteries inserted correctly?
First, make sure the batteries are installed and inserted in the
right direction (+/- according to the image in the battery slot).
Try testing the unit with batteries that are known to be of the
correct size and voltage (3.6 V Lithium, 3600 mA). If the
problem persists and the screen does not display anything,
contact technical support.
The Smart-Vue Pro Duo/Quatro data logger is properly
connected to the web platform. Why don’t I get any
temperature readings?
The Smart-Vue Pro wireless protocol is based on Smart-Vue
Pro LoRaWAN technology. The data logger connects
wirelessly to your Smart-Vue Pro LoRaWAN-enabled receiver
and transfers data periodically but not at every reading. If you
modify data logging settings in Smart-Vue Pro, the values on
the Smart-Vue Pro Duo/Quatro screen will be updated when
the next reading interval occurs. Wait for the next transfer
interval to get your data updated.
This could also be due to a loose cable or improperly
connected temperature sensor. Check the cable between the
Smart-Vue Pro Duo/Quatro data logger and the sensor.
Unplug the sensor and plug it back in. Make sure there are no
exposed wires. Try a different sensor.
Can external sensors be submerged in glycol?
Yes, for all metal-tipped sensors but not the dual
temperature/humidity sensor (with the white Teflon/PTFE
casing). To “absorb” sudden variations in temperature, such
as those caused by opening and closing the chamber door,
you may submerge the metal part of the sensor in glycol or
glycerol. This limits inconsequential temperature variations
recorded by the sensor. Check your laboratory’s quality guide
for recommendations and make sure to use a volume of
glycol that corresponds to the volume of product(s) you are
monitoring. To achieve the same results, you may also delay
the transmission of alarms via the software and leave the
sensors exposed.
CAUTION:
Remember to use the “Reset battery”
function when you install fresh batteries but never
use that function unless you actually change the
batteries.
