FNIRSI DMC-100 is a digital clamp meter for universal measurements in electrical equipment. The device integrates the functions of measuring current, voltage, resistance and many other parameters, while enabling non-contact voltage testing. Thanks to its clamp design and 25 mm diameter hole, the DMC-100 is suitable for both home work and professional service use.
The meter supports testing of AC/DC current, AC/DC voltage, resistance, capacitance, circuit continuity, diodes, frequency, temperature, and neutral and phase wire. Thanks to the NCV (non-contact voltage detection) function, the presence of voltage can be quickly checked without the risk of touching the wires.
The use of two independent measuring circuits enables the simultaneous measurement of voltage and current with automatic power calculation. This function speeds up diagnostics and eliminates the need for additional instruments.
The device offers measurement accuracy based on True RMS technology and a resolution of up to 10,000 counts, which guarantees accurate readings even in the case of non-linear signals. The graph and data recording function allow analysis of up to 30 series of results, with the possibility of viewing the last 8 measurements.
The built-in 1500 mAh lithium battery ensures long operation without recharging. The USB-C connector is protected from dust and damage by a silicone cap. The 2" color LCD display and built-in flashlight enable work even in poor visibility conditions.
