Built for Aussie HVAC&R pros, the Fieldpiece LT16A delivers accurate, reliable readings on real job sites — from flame rectification to three-phase rotation. Pair it with Fieldpiece accessory gear and you’ve got one meter that covers electrical and non-electrical checks. Less gear to lug, fewer call-backs. Too easy.
Key Features & Trade Benefits
- True RMS accuracy — Trust your readings on noisy signals, reducing misdiagnosis and repeat visits.
- Phase rotation testing — Confirm motor direction on three-phase gear before start-up, saving rework time.
- 400A AC clamp (ACH4) — Measure current without breaking the circuit for faster, safer checks.
- MIN/MAX hold — Capture highs and lows when you’re working solo.
- Silicone leads with detachable tips — Flexible, durable, and grippy in tight panels and summer heat.
- Tilt stand & magnetic hanger — Go hands-free while keeping the display in view.
- Accessory ecosystem — Expand into temperature, airflow, microamps and more using compatible Fieldpiece heads.
Why This Multimeter Matters
When you’re up on a roof in 40-degree heat, you need kit that just works. The LT16A is a fair dinkum workhorse — it plays nicely with Fieldpiece accessory gear, so you can add capability without another bulky meter. One contractor told us he chased a nuisance trip on a supermarket condenser: MIN/MAX flagged a voltage dip under load, phase rotation checked out, and the fix was sorted before lunch. That’s the difference between guessing and getting it right first go.
Building out your testing setup? For a tidy lead bundle and quick swaps on site, consider the Fieldpiece ADK7 Deluxe Lead Kit — a ripper pairing with the LT16A.
Pro Tip
For three-phase checks, use the yellow phase rotation lead with the magnetic hanger. Set your range first, hang the meter clear of moving parts, then probe once — no juggling. She’ll be right.

FAQs
Does the LT16A work with Fieldpiece accessory heads?
Yep. It’s built for the Fieldpiece ecosystem via standard banana jacks.
Can I measure higher currents safely?
Use the included 400A ACH4 clamp to measure load without opening the circuit — fast and safe.
Is it suitable for refrigeration service work?
Absolutely — microamps for flame rectification, capacitance for start/run caps, plus MIN/MAX and True RMS for accurate diagnostics.
