EC MODULE TROUBLESHOOTING
Map doesn’t match known or expected soil types --
1. Check electrical continuity using Implement Test Box as discussed above.
2. Check isolation of coulter electrodes
3. Remove any buildup of moist soil on toolbar
4. Check blade bolt tightness and corrosion
5. Map additional fields to see if similar condition results
6. Contact Veris Service Department
EC values change with field speed, or when unit stops moving
(If both shallow and deep EC array values change, focus on coulters 2 & 5; if shallow array coulters 3
& 4; if deep array coulters 1 & 6)
1. Check electrical continuity carefully—rotating coulter blade as measurement is made
2. Remove coulter hub cap and inspect spring-loaded commutator and coulter spindle for wear;
replace commutator or grind spindle end smooth if necessary
No conductivity readings on instrument display--
1.
No continuity on coulter electrode # 2 or # 5.
2. Check for excessive corrosion on coulter terminal.
3. Check for broken signal wire by disconnecting wire from coulter electrode and checking
continuity from end of wire to corresponding terminal on test box. Replace coulter wiring (PN
15601) or signal cable (PN 13602) as required.
4. Check for collapsed spring-loaded commutator on # 2 or # 5.
Data missing from display reading –
1. Unit must be in contact with soil to record data points; lower unit or add weights to ensure
consistent 1”-2” (2.5-5 cm) penetration into soil
2. Check GPS and DGPS signal; Veris instrument is programmed to eliminate all non-DGPS geo-
referenced points.
3. Shut power off and restart
4. Check electrical continuity: coulter electrodes to terminal…terminal to instrument.
5. Check input voltage, 12 v minimum required
Excessive number of negative readings in data --
1. Increase depth of penetration.
2. Slow down in extremely rough fields.
3. Alter transect pattern to avoid areas of heavy residue (combine swath)
Instrument has “locked up” and is not responding --
1. Shut off power and restart. Download the file that you were creating at the time the problem
occurred. Continue mapping the field. The files can be combined later in your spreadsheet.
2. Check for diskette in drive. Do not start up the instrument with a diskette inserted in the drive.
File will not download –
1. Try again
2. Check to see if you are receiving DGPS signal; system eliminates all non-DGPS geo-referenced
points
3. Restart computer and try again
4. Try another diskette.
5. Use Rescue Disk (Veris part #12330) to download files. Follow instructions on Rescue Disk
label.
6. Use serial port download function
Time or date on instrument display is incorrect or needs to be reset for new time zone--
1. Insert Time Set Disk (Veris part #-12331) to adjust time or date. Follow instructions on Time Set
Disk.
