Maintenance and Lubrication
Proper maintenance and lubrication of the Veris MSP 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) Coulter electrode isolation
– check so see that no metal part of the any
coulter electrode is in contact with the implement frame. This may be by
visual inspection or by connecting one lead of an ohmmeter to the individual
coulter electrode, and the other to a grounded fastener on the frame. If the
coulter electrode is properly isolated, no reading will be obtained. Make sure
that all electrode coulter clamp bolts are properly tightened to prevent lateral
movement of the coulter electrode.
Figures 1 and 2
2) Signal Continuity – To properly measure conductivity, good electrical signal
continuity must be present from the coulter electrode to the instrument. The
Implement Test Box (Part No. 10759) allows you to quickly check this.
Use the following method:
a) Connect the signal cable to the terminal on the test box.
b) Touch one lead of an ohmmeter to the #1 coulter blade (left hand,
standing behind the unit) and the other lead to the #1 terminal on the test
box. A reading of less than 2 ohms is normal.
