Indicator not to be subject to shock, excessive vibration or extremes of temperature (before or after installation).
•
Inputs are protected against electrical interference, but excessive levels of electro-magnetic radiation and RFI
may affect the accuracy and stability.
•
For full EMC or for RFI immunity, termination of cable shields and correct earthing of the instrument is
essential.
•
Indicator and load cell cable are sensitive to excessive electrical noise. Install well away from any power or
switching circuits.
