Details for FNIRSI DMC-100 True RMS AC/DC Clamp Meter | 600A, 10,000 Count

Product overview

FNIRSI DMC-100 is a rechargeable 10,000-count True RMS clamp multimeter designed for electricians, technicians, automotive troubleshooting, solar and battery-system checks, and general electrical maintenance. Its clamp measures AC or DC current without opening the circuit, while the included test leads support voltage, resistance, capacitance, frequency, diode, and continuity measurements. A 2.0-inch 240 × 320 color TFT display provides numerical readings, minimum/maximum values, waveform trends, and a power-measurement screen. The compact 25 mm (0.98 in) jaw is suited to individual conductors in panels, equipment, and vehicle wiring. Manual range selection, data hold, storage for up to 30 records, NCV screening, live-wire identification, a flashlight, and USB-C charging make it a versatile field tool.

Key Features

  • 10,000-count True RMS measurement with AC/DC clamp current up to 600 A
  • DC voltage up to 999.9 V and AC voltage up to 750.0 V
  • General, waveform, and calculated power measurement modes
  • 2.0-inch 240 × 320 color TFT display with adjustable brightness
  • NCV screening, live-wire identification, continuity, diode, resistance, capacitance, frequency, and temperature functions
  • Built-in 3.7 V 1500 mAh battery with USB-C 5 V/1 A charging

Best For / Typical Applications

Configuration Guide

This listing contains one Standard Kit. The former country-of-dispatch choices have been removed because they did not represent different product configurations.

Compatibility

No mobile app is specified. The USB-C port supports charging and firmware transfer. FNIRSI states that firmware updates must be performed on Windows 10 or Windows 11; macOS is not supported for firmware updating and may render the device inoperable.

What’s Included

  • DMC-100 clamp multimeter
  • Red and black test leads
  • Temperature probe
  • USB Type-C charging cable
  • User manual and retail box

Important Limitations

  • Clamp one insulated conductor at a time; clamping a complete cable containing both supply and return conductors can cancel the magnetic field and produce an incorrect current reading.
  • The 25 mm jaw may not fit large service or industrial conductors.
  • NCV and live-wire indications are screening aids, not proof that a circuit is de-energized.
  • The supplied specifications do not establish an independently verified measurement-category certification. Do not assume suitability for high-energy service entrances or distribution equipment solely from markings shown in product images.
  • Temperature accuracy depends on the supplied probe, contact, and operating conditions.

Safety & Use Notes

Inspect the meter, clamp, leads, and insulation before use. Hold probes behind the finger guards and never touch input terminals during a measurement. Disconnect the probes before changing the range or function. Use additional caution above 36 V DC or 25 V AC. Do not use in flammable or explosive environments, and do not operate the meter while it is charging.

Frequently Asked Questions

Does the clamp measure both AC and DC current?
Yes. Select the appropriate AC or DC current mode and zero the DC-current reading before measurement.

Is the DMC-100 auto-ranging?
No. The documented measurement ranges are selected manually.

Can I clamp around an appliance power cord?
Normally no. Clamp around a single conductor; enclosing both live and neutral can cancel the fields.

Can I update firmware from a Mac?
No. FNIRSI specifies Windows 10 or 11 for firmware updates and warns against using macOS.

Compatibility and requirements
Standalone measuring instrument; no mobile app or Bluetooth connection is required. The meter can display English or Chinese. FNIRSI firmware tools are advertised for Windows 10/11 only; the manufacturer warns that macOS updates are unsupported and may damage the device.
Limitations and product fit
Clamp only one conductor at a time. The 25 mm jaw opening limits conductor size. NCV is a screening function and must not be used as proof that a circuit is de-energized. The temperature range shown by the meter does not override the temperature probe’s own safe range. Accuracy figures are manufacturer-stated specifications, not an independent calibration certificate. A measurement-category certification was not independently verified for this listing.
Safety and handling
Inspect the case, jaw, leads and insulation before use. Keep fingers behind probe and clamp guards. Do not touch exposed terminals. Disconnect test leads before changing functions or opening the jaw around a conductor. Use extra caution above 36 V DC or 25 V AC. Do not operate the meter while it is charging or in explosive environments. NCV detection does not replace a properly rated contact tester and lockout/tagout procedures.
Warranty information
Store warranty and return terms apply; no separate manufacturer warranty term is claimed for this listing.
Frequently asked questions
Q: Can the clamp measure DC current?
A: Yes. The DMC-100 measures both AC and DC clamp current up to 600 A. Zero the DC-current reading before measurement and clamp one conductor only.

Q: Does it measure voltage through the clamp?
A: No. Voltage, resistance, capacitance, frequency, diode, continuity and temperature measurements use the supplied input leads or probe.

Q: Is NCV proof that a wire is safe to touch?
A: No. NCV is a screening aid. Confirm de-energized status with an appropriately rated contact tester and follow applicable safety procedures.

Q: Can it be used while charging?
A: No. The manual instructs users not to measure while the meter is charging.

Q: Does it connect to a phone?
A: No phone app or Bluetooth function is specified.

Q: What computer is needed for firmware updates?
A: FNIRSI lists Windows 10/11; its firmware page warns that macOS updates are unsupported.
