Professional FAQ

• Q: How do I set current output range for a channel?
  A: Use the module software menu to select 4–20 mA. Then verify with a calibrated meter during run-up.
• Q: What routine checks improve long-term accuracy?
  A: Perform yearly calibration and check zero/span drift under load.
• Q: How do I reduce ground loop errors on analog lines?
  A: Ground shields at the controller end and isolate large equipment grounds.
• Q: What steps fix unstable analog outputs after installation?
  A: Confirm wiring integrity, replace suspect cables, and re-run calibration.
• Q: How do I test isolation between channels safely?
  A: Use a high-voltage tester at rated isolation voltage with power removed, following safety rules.
