How These Tools Work (Even if You're Not a Tech Geek)

You don’t need to be a tech wizard to use these. The SMAN manifold line uses digital pressure sensors and thermocouples to give fast, accurate readings. Everything’s displayed on a bright backlit screen, and with the Job Link app, you can track and store service logs, reducing paperwork and time on site.

Here’s what a typical workflow might look like:

1. Connect the hoses to the system.

2. Insert temperature clamps.

3. Activate the Job Link app.

4. Monitor superheat, subcooling, and pressures live.

5. Make adjustments and save the job data on your phone or tablet.

It’s that easy—and yes, the Fieldpiece site backs this up with full manuals and video walkthroughs if you're new to digital manifolds.

Aussie Techs Speak: Real Feedback from the Field

Josh, Brisbane HVAC Tech

“The SM480V has been a lifesaver. I'm usually servicing five supermarkets a week and the wireless hookup means I’m not juggling hoses and trying to write notes at the same time. Plus, it's tough as nails.”

Mandy, VIC-based refrigeration contractor

“We made the switch from analog to digital last year and haven’t looked back. Being able to show live readings to the store manager builds trust and saves arguments.”

Tips for Aussie Tradies: Getting the Most Out of Your SMAN

• 🛠 Always update your Job Link app – New firmware often improves accuracy.

• 🔌 Carry extra AA batteries – Especially in rural areas.

• 🌦 Wipe down after use – These are weather-resistant but will last longer with care.

• 🧪 Use with Fieldpiece temperature clamps and vacuum pumps for a full suite of diagnostics.
