The transmitter will only accept full-scale adjustment when the pressure readout is within 600 to 1000 mbar. Note that if the adjustment is performed at a true pressure different from 1000 mbar, it can cause measurement deviations in the upper part of the measuring range. 300544652_002_C1 - 11/2016 - © Leybold... -

Page 25: Faq (Frequently Asked Questions)
Factors that temporally or permanent can influence the measuring performance is contamination, corrosion, heat and electronic interference. Q: Will the transmitter retain user calibration after power is shut off? A: Yes - All transmitter parameters including calibration data is stored internally in the transmitter nonvolatile memory. 300544652_002_C1 - 11/2016 - © Leybold... - Page 26 Q: Reverse voltage has been connected to power supply input. Is the transmitter damaged? A: Not likely – The transmitter power supply circuit has reverse voltage and over voltage protection however, Leybold cannot guarantee that the transmitter will not be damaged. Q: The status light ring is constantly illuminating red? A: The red status indicates a defect sensor element most likely damaged by corrosion or contamination.
