Bluetooth multimeter logging: how to capture and export readings (Fluke Connect, Megger MFT-X1, Kewtech, UNI-T)

Electrician logging Bluetooth multimeter readings to a phone at a UK consumer unit

Contents

Quick answer

If your meter or tester supports Bluetooth, you can stream and log readings to a phone, then export to CSV or PDF for reports. Popular options used by UK sparkies include:

  • Fluke Connect with FC meters and clamps for live trending and CSV export. See Fluke’s UK pages on logging and exporting with the app: Fluke Connect with clamps and Fluke Connect overview.
  • Megger MFT-X1 pairs over Bluetooth to the CertSuite mobile app to move results straight into NICEIC-style certificates. See Megger CertSuite and the MFT-X1 product page.
  • Kyoritsu/Kewtech testers connect to KEW Smart Advanced or Kewtech Connect apps for viewing and saving results. See KEW Smart Advanced.
  • UNI-T meters use the Smart Measure app or a UT-D07 Bluetooth adapter to send readings to your phone. See UNI-T Smart Measure.

Who this is for

  • Domestic and commercial electricians who want cleaner records for EICR/EIC, fault-finding, and handovers.
  • Supervisors who want engineers to attach real measurements to job packs without extra admin.
  • Apprentices who want to learn good evidence habits from day one.

What you can log and why it matters

  • Intermittent faults: capture a current spike, voltage sag, or nuisance RCD trip over time, not just a snapshot.
  • Commissioning evidence: trend L1/L2/L3 current under load; record inrush on motors or EV charge points; log Zs/IR sequences from an MFT.
  • Documentation: attach a CSV or PDF graph to your job, EICR, or client email. It looks professional and avoids disputes.

Before you start: safe isolation and setup

  • Follow BS 7671 safe isolation. Set up your phone before opening any live enclosures.
  • Charge batteries on both phone and meter; logging can run 10 to 60 minutes or more.
  • Label assets in the app (e.g., “CU flat 4” or “AHU-2”) so exports make sense later.

Step-by-step by brand

Fluke Connect (FC clamp/meter)

Fluke’s mobile app connects to compatible “FC” tools over Bluetooth LE for live viewing, logging, and export.

  • Install the Fluke Connect app (iOS/Android) and sign in. See Fluke’s UK how-to: using Fluke Connect with clamp meters and real-time troubleshooting.
  • Pair your meter in the app, select the function (e.g., AC current), pick a logging interval/duration, then Start.
  • When finished, Stop and Download to save the session under Measurements.
  • Export as CSV or PDF from the session to email or your files. Desktop software is also available: Fluke Connect sw3000fc.

What it’s best for

  • Trending current on individual breakers, monitoring inrush, and catching sags/spikes while you are working elsewhere on site.

Megger MFT-X1 with CertSuite

Megger’s MFT-X1 sends test results to the CertSuite app over Bluetooth so you can build the certificate as you test.

  • Install CertSuite and sign in. See the UK pages: CertSuite overview and MFT-X1.
  • Pair your MFT-X1, select the job/circuit, run the test (IR, continuity, loop, RCD), and sync the result.
  • Use CertSuite circuit templates to speed up repetitive board layouts. Megger’s video walkthrough: MFT-X1 and CertSuite.

What it’s best for

  • Turning on-site MFT results straight into certs without retyping, especially useful for EICR/EIC.

Kewtech and Kyoritsu apps

Kyoritsu/Kewtech testers use KEW Smart Advanced or Kewtech Connect.

  • KEW Smart Advanced supports a range of KEW-series instruments (e.g., KEW6514BT MFT, KEW2433RBT clamp). App page: KEW Smart Advanced.
  • Kewtech Connect supports selected Kewtech models (e.g., KT220 clamp). App page: Kewtech Connect.
  • Pair in the app, select the instrument, start capture, and save/export as required.

What it’s best for

  • Quick transfer of test readings and photos into a job record using budget-friendly testers.

UNI-T Smart Measure

UNI-T meters can log to the phone with Smart Measure. Some models need a UT-D07 Bluetooth adapter.

What it’s best for

  • Affordable logging for basic voltage/current/resistance jobs and training.

Export and share: CSV and PDF naming

  • Use CSV when you want to graph or combine datasets later in Excel/Sheets.
  • Use PDF when you want a quick, client-friendly attachment.
  • Naming tip: Project-Site-Board-Point-YYYYMMDD-HHMM.csv (e.g., “Acme-Unit12-CU1-L1-20251003-0930.csv”).
  • Store exports in the same job folder as your photos and certificate files.

Troubleshooting Bluetooth on site

  • Range: Bluetooth LE is short range. Keep the phone near the meter if it’s streaming live.
  • Permissions: On iOS/Android, allow Bluetooth and Location for the app or it will not pair reliably.
  • Battery saver: Disable Low Power/Battery Saver during long logs.
  • Interference: Steel cabinets and plant rooms can kill signal. If your tool supports internal logging, use it and sync later.
  • Firmware: Update the app and your instrument’s firmware; vendors fix pairing and logging bugs regularly.

Workflow tips and automations

  • Add photos: Shoot the nameplate and the breaker you tested. Most apps let you attach images and notes.
  • Tie logs to certificates: If you use CertSuite or other software, keep filenames consistent so anyone can find the evidence.
  • Automate admin: If you use iPhone, set up a Shortcut to rename and file exports in one tap. See our guide: iPhone Shortcuts for trades: 3 fast automations you can set up today.

FAQ

Can I log without keeping my phone next to the panel?

Some meters only stream live to the phone (so you must stay in range). Others can log internally and sync later. Check your model’s manual.

Will this help with EICR evidence?

Yes. A CSV or PDF trend shows exactly what happened under load. Combine it with photos and your certificate for strong evidence.

Is Bluetooth allowed on all sites?

Some industrial sites restrict phones and radios. Follow the site rul…
