Chauvin Arnoux F404T Key Features:
- Patented Autocheck: check instrument operation as part of DC no-current verification
- Wide measurement capability: up to 1,000 A AC, 1,500 A DC, 1,200 V AC and 1,700 V DC
- TRMS measurement: True RMS capability for electrical testing
- Automatic AC/DC detection: available for both current and voltage measurements
- TrueInrush function: capture starting current to support conductor and protection assessment
- Dual backlit display: 10,000-count readout for viewing measurements
- Test lead resistance compensation: automatically account for lead resistance
- Additional measurement functions: temperature, relative and differential measurements, plus an adapter input for external probes
Why choose the Chauvin Arnoux F404T?
When a current reading informs the next stage of a job, checking the instrument itself is a useful part of the process. Autocheck adds that capability to a clamp meter with the broader functions needed for field measurements.
The controls are designed for one-handed operation, including use with protective gloves. Dedicated measurement positions and function buttons help make selecting the required check straightforward during site work.

❓ Frequently Asked Questions (FAQ)
Q1: What does Autocheck actually verify?
A. It checks that the instrument is operating correctly after DC zero adjustment. A “YES” result confirms self-check success; it does not establish that the installation is voltage-free.
Q2: Does the F404T automatically select AC or DC?
A. Yes. Automatic AC/DC detection is available for current and voltage measurements. Manual selection is also available.
Q3: Is the maximum DC measurement range the same as the CAT rating?
A. No. The maximum DC voltage measurement is 1,700 V, while the measurement category ratings are CAT IV 1,000 V and CAT III 1,500 V. Select the instrument and accessories for the installation’s required category and voltage.
Q4: Is a temperature sensor included?
A. Yes. A temperature sensor is supplied alongside the test leads and accessories, carrying case and batteries.
