As a field technician, you often need fast answers while on-site with a customer. Circuit gives you instant access to your workspace’s technical documentation through a chat interface.

Common scenarios

​
Troubleshooting an error code

Instead of searching through multiple PDF manuals, describe the situation:
The XYZ-500 unit at the customer site is displaying error code E-47. The unit was installed in March 2024 and has been running fine until today. What should I check?
The agent will find the relevant troubleshooting procedure, walk you through diagnostic steps, and cite the source manual so you can pull it up if needed.

​
Finding installation procedures

When you need step-by-step guidance for a specific configuration:
I need to install the XYZ-500 in a ceiling-mounted configuration in a room with limited clearance (2.4 meters). What are the clearance requirements and mounting steps?
Include the specific model, mounting type, and any site constraints to get a procedure tailored to your situation.

​
Looking up part numbers and specifications

What replacement filters are compatible with the XYZ-500? I need the part numbers for both the standard and high-capacity options.
What is the torque specification for the mounting bolts on the XYZ-500 bracket assembly?

​
Checking maintenance procedures

The customer wants to know the recommended maintenance schedule for their XYZ-500. They run it about 16 hours a day in a dusty environment. What should they be doing and how often?
The environmental context (dusty, heavy use) helps the agent provide adjusted intervals rather than just the standard schedule.

​
Tips for field use

Be specific about the model and conditions. Agents work best when you include the exact model number, installation type, operating conditions, and any symptoms or error codes.
  • Include the environment: temperature, humidity, dust levels, and operating hours affect recommendations
  • Mention what you’ve tried: “I already replaced the filter and the error persists” helps the agent skip to the next diagnostic step
  • Ask for safety warnings: “Are there any lockout/tagout requirements before I open the access panel?”
  • Request part numbers explicitly: the agent can pull these from catalogs and manuals if you ask
