Maintenance and Lubrication
Proper maintenance and lubrication of the Veris P4000G will allow you to collect high
quality NIRS and EC data, and greatly extend the useful life of the unit. Veris
Technologies strongly suggests that you follow the following guidelines:
MAINTENANCE: Storage of Spectrophotometer
Spectrometer and Auxiliary cases are water resistant; store NIRS system indoors or
under roof. Water damage to spectrometers and electronic components is not covered
by warranty.
MAINTENANCE: Electrical Continuity and Isolation
It is advisable to perform this test on a routine basis (weekly or every 20-25 hours of
data collection) to ensure you are obtaining reliable data.
1) Probe electrode isolation – Check isolation of the dipole to the point with a
Digital Multi Meter if the coulter electrode is properly isolated, a reading of
12K ohm should be obtained.
