The table below clearly outlines the key differences and similarities between the DT-9380 and DT-9380A AC clamp meters to help you choose based on your needs.
| Feature & Function | DT-9380 | DT-9380A | Comparison & Advantage |
|---|---|---|---|
| Core Measurement | |||
| AC Current Measurement | Yes (1000A, True RMS) | Yes (1000A, True RMS) | Both use True RMS technology for accurate measurement of non-linear loads. |
| DC Current Measurement | No | No | Both are AC-only clamp meters and cannot measure DC current. |
| Display & Precision | |||
| Display Counts | 4000 counts | 6000 counts | DT-9380A offers higher display resolution for finer readings, especially advantageous for low current/voltage measurements. |
| Basic Accuracy | Per specifications | Per specifications | Both provide reliable accuracy within their respective ranges. |
| Advanced Diagnostic Features | |||
| Inrush Current Measurement | No | Yes | A key exclusive feature of the DT-9380A. Accurately captures the instantaneous high current during motor or transformer startup for analyzing inrush characteristics and breaker sizing. |
| Low Impedance (LoZ) Voltage Mode | No | Yes | A key exclusive feature of the DT-9380A. Eliminates misleading "ghost voltage" readings caused by induced voltage, ensuring true and reliable voltage readings on de-energized lines or long cable runs. Enhances safety. |
| Low Pass Filter (LPF) | No | Yes | A key exclusive feature of the DT-9380A. Filters out high-frequency noise when measuring voltage/current on Variable Frequency Drive (VFD) outputs, providing stable fundamental frequency readings. Essential for VFD maintenance and commissioning. |
| Data Functions | |||
| Data Hold | No | Yes | Supported by DT-9380A, useful for freezing readings in hard-to-see places. |
| Relative (Zero) Function | No | Yes | Supported by DT-9380A, useful for measuring differences or nulling test lead resistance. |
| Max/Min Hold | Yes | Yes | Both support recording peak values during measurement. |
| Safety & Convenience | |||
| Non-Contact Voltage (NCV) Detection | Yes | Yes | Both feature built-in NCV for quick live wire detection. |
| Flashlight & Backlight | Yes | Yes | Both equipped for working in low-light conditions. |
| Auto Power Off | Yes | Yes | Both supported to conserve battery life. |
| Design | |||
| Jaw Opening | 35mm (1.4 inches) | 35mm (1.4 inches) | Same, fits most cables and busbars. |
| Housing | Dual-molded | Dual-molded | Same, durable and drop-resistant. |
| Typical Application | General electrical maintenance, load checks, wiring installation, basic troubleshooting. | Motor circuit diagnostics, VFD system maintenance, industrial control panel troubleshooting, complex electrical environments requiring ghost voltage elimination, and applications demanding higher measurement precision. | The DT-9380A is engineered for more complex and demanding electrical diagnostic tasks. |
