Metal Samples MS2601E - Maintenance; Troubleshooting

16
C. Maintenance
Once installed, the MS2601E requires little maintenance. However, it is important to verify the following
items periodically to ensure continued safe operation.
CAUTION:
Before performing any tests or maintenance on the MS2601E, ensure that all hazardous area
requirements are met.
Inspection Item
Frequency
Inspect the enclosure o-ring for any signs of damage. Replace as necessary.
Annually
Inspect the probe connector o-ring for any signs of damage. Replace as necessary.
Annually
Inspect all electrical connections for signs of corrosion, mechanical damage, or foreign
matter that could cause improper operation or cause an electrical short. Clean as necessary.
Annually
Ensure that the locking screw is in place and is secure.
Annually
Inspect the enclosure for any signs of corrosion or paint damage.
Annually
Check for any signs of moisture ingress within the enclosure.
Annually
Contact Metal Samples for replacement parts or if instrument repair is necessary.
D. Troubleshooting
If the MS2601E does not seem to perform as expected, check the following items:
CAUTION: Before performing any tests or maintenance on the MS2601E, ensure that all hazardous
area requirements are met.
ATTENTION: avant d'effectuer des tests ou des opérations de maintenance sur le MS2601E, assurez-
vous que toutes les exigences relatives aux zones dangereuses sont respectées.
1. Ensure that the probe is operational and is not completely corroded. This can be done in two
ways.
a. Test the probe with a portable ER meter if available.
b. Test the probe with a portable resistance or continuity meter as follows:
i. Connect one test lead to pin ‘A’ of the probes 6-pin connector.
ii. Measure continuity to each of the other pins. There should be continuity (low
resistance) to each pin.
NOTE: Continuity on each pin does not ensure that the probe is good. However, if
you find an open circuit on any pins then it is almost certain that the probe is bad and
should be replaced.
2. Ensure that the Probe Selection Switches are set correctly for the probe being used. Confirm
the probe type, and refer to Table 2 on page 9 to verify the appropriate switch settings.
3. Perform a visual inspection of the circuit boards to look for any signs of mechanical or
electrical damage.
4. Ensure that all electrical cables and wiring are in good condition.
5. Ensure that all electrical contacts are secure and free of corrosion.
