Modern HVAC work is all about working smarter, not harder. If you’re still kneeling next to a vacuum pump watching micron numbers crawl down, you’re wasting time — and energy.
The Fieldpiece MG44 Wireless Micron Gauge, when paired with the Job Link® app, gives you hands-free, real-time vacuum monitoring directly from your phone or tablet. Once you set it up properly, you’ll never want to go back to hovering over a gauge.
In this guide, I’ll walk you through exactly how to connect the MG44 to the Job Link app, plus a few pro tips to get the most out of it on real HVAC jobs.
Why Use the Job Link App With the MG44?
Before diving into setup, it’s worth understanding why this matters.
Connecting the MG44 to Job Link allows you to:
- Monitor micron levels remotely
- Perform accurate decay tests without touching fittings
- Reduce trips back and forth to the pump
- Keep your evacuation setup undisturbed
When combined with other HVAC tools like a digital manifold, this creates a clean, professional workflow — especially when working with modern refrigerant systems.
What You’ll Need Before You Start
Make sure you have:
- Fieldpiece MG44 Wireless Micron Gauge
- A smartphone or tablet (Android or iOS)
- The Fieldpiece Job Link® app installed
- Bluetooth enabled on your device
Optional (but recommended for a full setup):
- A digital manifold such as the SM482V Manifold
Step-by-Step: Connecting the MG44 to the Job Link App
Step 1: Install the Job Link App
Download the Fieldpiece Job Link® app from:
- Google Play Store (Android)
- Apple App Store (iOS)
Once installed, open the app and allow:
- Bluetooth access
- Location permissions (required for Bluetooth scanning)
Step 2: Power On the MG44
Turn on the MG44 by pressing the power button.
Make sure:
- The batteries are fresh
- The gauge powers up normally
- You’re within a few meters of your mobile device
The MG44 will automatically enter pairing mode when powered on.
Step 3: Open Job Link and Add the MG44
In the Job Link app:
- Open the app
- Tap “Add Tool” or “+”
- Select MG44 Wireless Vacuum Gauge from the list
Within seconds, the app should detect the MG44 and connect automatically.
Once paired, you’ll see live micron readings on your screen.
Step 4: Confirm Live Data
To confirm everything is working:
- Watch the micron reading update in real time
- Gently move the system or start the vacuum pump
- Confirm the numbers respond instantly
If the reading changes smoothly, you’re fully connected.
Pro Tips for Hands-Free Evacuations
Mount the MG44 at the System
For best accuracy:
- Install the MG44 directly on the evaporator or liquid line
- Avoid mounting it at the pump or manifold
This eliminates hose leaks from your readings and gives you true system vacuum.
Leave the System Undisturbed
Once the MG44 is connected:
- Do not touch hoses or fittings during evacuation
- Watch decay tests from your phone
- Let the system stabilise naturally
Hands-free monitoring improves accuracy and confidence.
Pair With the SM482V Manifold
For a complete Fieldpiece workflow:
- Use the MG44 to verify deep vacuum
- Use the SM482V Manifold to monitor pressure and refrigerant conditions
The SM482V Manifold handles system diagnostics, while the MG44 focuses purely on evacuation quality — a professional division of roles that reduces mistakes.
Common Connection Issues (And How to Fix Them)
MG44 not appearing in the app?
- Make sure Bluetooth is enabled
- Power-cycle the MG44
- Close and reopen the Job Link app
Connection drops occasionally?
- Stay within Bluetooth range
- Replace weak batteries
- Avoid excessive interference from other devices
In most cases, reconnection is quick and automatic.
Why This Setup Changes How You Work
Once connected, the MG44 + Job Link combination allows you to:
- Walk away while evacuating
- Set up other tools
- Prepare refrigerant charging
- Monitor progress without babysitting the pump
It’s a small change that delivers real productivity gains — especially on longer evacuations.
Who This Is Perfect For
This setup is ideal if you:
- Perform regular evacuations
- Want accurate decay testing
- Are tired of chasing false leaks
- Use professional HVAC tools
- Work with moisture-sensitive refrigerant systems
If evacuation quality matters, hands-free monitoring is no longer optional.
Final Thoughts
Connecting the Fieldpiece MG44 to the Job Link app takes less than a minute — but the efficiency gains last for years. You get accurate system-mounted vacuum readings, hands-free monitoring, and a cleaner workflow from start to finish.
When combined with tools like the SM482V Manifold, the MG44 becomes part of a fully integrated Fieldpiece setup built for modern HVAC professionals.
Conclusion
