8.2 Reducing measurement noise
Excess cable lengths may be prone to electrical noise. The cable should be long enough to form a
drip loop, which helps prevent water ingress into the data logger enclosure. However, excess
cable coiled in the enclosure should be avoided.
AC power lines, pumps, and motors can be the source of electrical noise. If the TempVue 10
probe or data logger is located in an electrically noisy environment, the measurement should be
made with the 60 or 50 Hz rejection options.
Offsets in the measurement circuitry may be reduced by reversing the differential analog inputs
(
RevDiff
).
9. Maintenance,
troubleshooting, and calibration
NOTE:
All factory repairs and recalibrations require a returned material authorization (RMA) and
completion of the “Statement of Product Cleanliness and Decontamination” form. Refer to
the
page at the end of this manual for more information.
9.1 Maintenance
The TempVue 10 requires minimal maintenance. Periodically check cabling for proper
connections, signs of damage, and possible moisture intrusion.
Check the radiation shield monthly to make sure it is free from dust and debris. To clean the
shield, first remove the sensor. Dismount the shield. Brush all loose dirt off. If more effort is
needed, use warm, soapy water and a soft cloth or brush to thoroughly clean the shield. Allow
the shield to dry before remounting.
Ensure the TempVue 10 probe is clean and free of dirt or any soiling by wiping carefully with a lint
free cloth and warm soapy water.
