What the meter sends
In plain words, a ZOYI meter sends the reading and its unit over Bluetooth, about three times a second. That is all it sends. The app shows what the meter sends and does not change how it measures.
To connect, turn on the meter's Bluetooth: on the ZT-5B with a short press of the power button, on other models as their manual describes. A Bluetooth symbol appears on the meter's display, and the meter shows up in the app's scan list as Bluetooth DMM. Tap it to connect; the app reconnects to your last meter on launch and after drops.
What is not available
A ZOYI meter only streams its readings, so the app cannot set the meter's function, range or hold. Use the app's own hold, REL and min/max.
Other ZOYI models
Some ZOYI meters are also sold as Aneng or BSIDE, and other ZOYI meters may use the same protocol. Only the models in the table are claimed. Have another one? Mail its model to support@testnmeasure.app.
What it does and doesn't do (yet)
| What it does | Plan |
|---|---|
| Finds supported Bluetooth meters nearby and lists them, with a clear path when Bluetooth or its permission is missing. | Free |
| Tap a result to connect; the meter becomes the active instrument and live readings start. | Free |
| Reconnects to your last meter on launch and after drops, and always shows the connection state. | Free |
| Keeps a list of your instruments with names you choose, so every reading is tied to the meter that took it. | Free |
| A simulated meter lets you try the whole app without hardware; it is labelled DEMO everywhere. | Free |
| Type the reading from any instrument; typed values are marked as manual. | Free |
| A large readout that shows which digits have settled; OL and UL are shown as OL and UL, never as a number. | Free |
| Swipe the readout to a live graph with min and max lines, pan and zoom. | Free |
| Hold freezes the displayed reading and statistics in the app, independent of the meter's own HOLD. | Free |
| Shows the running minimum, maximum and average since the last reset, with the sample count. | Free |
| Shows rolling averages over the last 5, 30 and 60 seconds. | Free |
| REL shows the difference from a stored reference, for example to null out test-lead resistance. | Free |
| Five stability bars show when a reading is steady. | Free |
| A landscape layout for the meter and run screens. | Free |
| Keeps the screen on while you measure, run a test or record. | Free |
| One tap saves the current reading, with an Undo. | Free |
| Log sessions hold captures and time-series recordings, and recording continues with the screen locked. | Free |
| Add a text note and a short label to any capture. | Free |
| Attach up to 5 photos to a capture. | Free |
| Record a voice note of up to 2 minutes on a capture. | Free |
| Scale readings with a factor and an offset, for clamp adapters, shunts and probe dividers; the raw reading is kept. | Free |
| Search and filter your history; deleted items stay in Recently deleted for 30 days. | Free |
| Review a session as a full graph with pan and zoom, statistics and its captures. | Free |
| Auto-record saves a capture when the reading becomes stable. | Free |
Not yet, or not planned
- One live Bluetooth meter at a time for now; two meters at once (voltage and current, with power) is coming.
Questions
Which ZOYI meters work with TestNMeasure?
All four in the table: the ZT-5B, ZT-5BQ, ZT-300AB and ZT-5566S. They share one ZOYI driver, and live readings from the ZT-5B were checked against the meter's display. Each model page lists what is still to be verified.
Do I need the e-Bull app as well?
No. TestNMeasure connects to the meter by itself. If the meter does not show up in the scan list, close the e-Bull app: it may still hold the connection.
Can I connect two ZOYI meters at once?
No. One live Bluetooth meter is connected at a time. Your instrument list remembers each meter by name.
