10.1 - Calibration
Your Nimbus IoT has been fully calibrated at the factory, and can be recalibrated in software
using Define WorkBench (see Section 6). Scaling to convert the input signal to a desired dis-
play value is also done using WorkBench
If your Nimbus IoT appears to be behaving incorrectly or inaccurately, refer to troubleshooting
before attempting to calibrate it. When recalibration is required (generally every 2 years), it
should only be performed by qualified technicians using appropriate equipment.
Calibration does not change any user programmed parameters. However, it may affect the
accuracy of the input signal values previously stored.
10.2 - Troubleshooting
Issue
Resolution
Power LED flashes orange
every 2-3 seconds con-
tinuously AND data log
samples have inaccurate
time/date
The most likely cause of this error is the long-life battery for
the real-time clock backup needs to be replaced. Contact our
service center for further instruction.
Power LED stays red
continuously
If the power LED stays red continuously this indicates an in-
ternal error which will need to be assessed by the manufac-
turer. Please return the Nimbus IoT to the manufacturer for
analysis and repair.
Cannot power up unit
Check the power supply connections and supply range.
Power LED flashes orange
multiple times followed
by a 2-3 second pause
The Nimbus IoT has encountered a non-critical error. Count
the number of orange flashes between the pauses and con-
tact our service center for further instruction. (Note: the
meaning of this condition may change with custom appli-
cations so be sure to mention if you are running a custom
application)
Power LED is mostly off
but flashes a short red
pulse every 3 seconds
The Nimbus IoT does not have enough power supplied for it
to run correctly. Check that the power supply voltage meets
the requirements shown in section 7.5 of this manual.
For further assistance, please contact technical support using the contact details listed at the
