c) Continue to check each coulter electrode in succession, left to right.
d) If any coulter electrode exhibits no continuity or resistance higher than 2 ohms, refer

to the maintenance or trouble shooting sections for possible causes.

Note: 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.

Instrument Signal Testing

– The Veris MSP pH Manager is shipped with an Instrument Test Load

(Part No. 10447) that will enable you to quickly check the instrument to ensure that it is functioning
properly. To perform this test, do the following:

1) Disconnect the signal cable from the 9-pin (signal) terminal on the instrument.
2) Connect the test load to the signal terminal.
3)

Switch on the unit and go into “data acquisition” mode.

4) The display should show: (approx.)

Shallow

Deep

5) If the readings vary significantly (more than one whole number) contact our service

department.

6) Once the test is complete, remove the test load and reinstall the implement signal cable.

Note: It is advisable to conduct this test as a routine check to ensure that you are obtaining reliable
EC data.

ADJUSTMENTS

Commutators-- The spring-loaded commutators are located in the center of each coulter

electrode hub cap. They are factory preset, and should not need

routine adjustment. If a continuity test shows abnormally high resistance,
