Conseil de sélection: Choose 376-FC for 1000A AC/DC, frequent VFD testing, high-current work and wireless logging. Choose 375-FC for applications within 600A.

Applications typiques

Moteurs industriels, variateurs de fréquence, distribution panels, UPS, Onduleurs photovoltaïques

Plant electrical maintenance, equipment commissioning, diagnostic de panne, motor inrush-current testing

On-site remote reading, data archiving and test-report generation

Usage & Notes d'entretien

The iFlex flexible coil measures AC only, DC measurements must use the meter’s physical jaws.
Enabling the VFD filter reduces bandwidth; disable it for standard power-frequency measurements.
In-Rush mode captures transient startup events and shall not be used for steady-state readings.
Second-hand inspection checklist: Undamaged jaws, intact iFlex coil, functional Bluetooth, sound lead insulation, valid calibration status.

Fluke 375-FC vs 376-FC Key Differences

Both support Fluke-Connect Bluetooth, VFD filter, In-Rush mode, DC-mV and True-RMS, with identical safety ratings. Differences lie in jaw current range, iFlex inclusion and crest factor.

Plain-language Explanation

375-FC: 600A upper limit

Suitable for most low-voltage distribution panels, motors and loads up to 400A. iFlex coil is sold separately. Cost-effective for routine plant maintenance where 600A is sufficient.

376-FC: 1000A jaw + factory-fitted iFlex

Designed for 800-1000A loads, jeux de barres, high-power UPS and high-power VFDs. Ready-to-measure up to 2500A AC out-of-box with no extra probe purchase.

⚠️ Remarque: iFlex flexible coil measures AC only. High DC current must be measured by the meter’s built-in jaws.

Guide de sélection

Most operating conditions ≤600A, rare high-AC-current work → 375-FC

Frequent 800-1000A measurements, regular large-AC-current testing, no wish to buy iFlex separately → 376-FC

Second-hand Purchase Notes

Many used 375-FC units do not include iFlex. Genuine complete 376-FC units come with the i2500-18 flexible coil.

For both models verify: VFD filter function, In-Rush mode, Bluetooth connectivity, jaw movement and lead insulation integrity.

Différences d'application: Fluke 375-FC vs 376-FC

Feature sets are nearly identical: VFD filter, In-Rush surge, Fluke-Connect Bluetooth and DC-mV are all present. Application gaps stem from two core points:

① Maximum jaw current: 600A AC/DC for 375-FC; 1000A AC/DC for 376-FC

② iFlex is factory-supplied on 376-FC but must be purchased separately for 375-FC.

🟢 375-FC Application Scope (600A jaw, iFlex optional)

For general-purpose plant maintenance with steady-state load current ≤600A and rare >600A DC measurements.

Medium-small VFD-driven motors: 30-200 kW motors, MCC cabinets; measure operating current, startup inrush and VFD output (VFD filter enabled).
General low-voltage distribution panels: Feeder circuits, ≤400A molded-case breaker loops; routine inspection and preventive maintenance with data logging.
DC-side work: DC power panels, small-capacity UPS and DC busbars, for DC currents no higher than 600A.
Bâtiments commerciaux, HVAC and general equipment commissioning: iFlex probe may be purchased later if occasional high-AC-current measurement is needed.
Maintenance teams: Majority circuits sit below 600A; cost-optimized choice when iFlex is not used daily.

⚠️ 375-FC Limitations

Jaw DC measurement is capped at 600A. DC above this value cannot be measured (iFlex works for AC only).

Flexible coil is not supplied; extra procurement required for large cables or tight-fit busbar measurements.

🔴 376-FC Application Scope (1000A jaw, iFlex standard)

Targets high-current scenarios, frequent 600-1000A AC/DC measurements and regular flexible-probe usage for large cables / jeux de barres.

Heavy-duty industrial motors: 200-450 kW motors with operating current at or above 600A; motor inrush testing and high-power VFD circuit diagnostics.
High-power UPS, low-voltage busbars and incoming cabinets: Transformer secondary and 800-1000A incoming-feed circuits; direct high-DC-current readings via main jaws.
PV and energy-storage PCS converters: Mixed AC-DC environments; capable of near-1000A DC readings which cannot be achieved by the 375-FC.
Frequent iFlex-probe deployments: Congested cable trays, busbars and oversized cables that cannot fit within standard jaws; 2500A-AC measurement capability available immediately out-of-box.
System integration, project commissioning & EPC sites: Mixed-spec loads covering low-ampere loops through kilo-ampere incoming feeds; one-meter coverage; remote readings for test-reporting and arc-flash hazard mitigation.

⚠️ 376-FC Caveat

iFlex remains AC-only; 1000A DC is measured exclusively through the physical meter jaws.
