The Proster Clamp Meter (PSTTL301) is designed for electricians, technicians, and DIY enthusiasts needing accurate AC/DC voltage and current measurements. Its key benefit is True RMS (TRMS) for precise readings on non-linear loads, with a caveat that advanced functions require familiarity with electrical testing principles. This 6000-count meter offers auto-ranging, non-contact voltage (NCV) detection, continuity testing, and overload protection, making it a versatile tool for troubleshooting in various environments.

True RMS (Root Mean Square) measurements provide the most accurate reading of AC voltage and current, especially on non-sinusoidal waveforms (like those from variable frequency drives or switching power supplies). Standard 'average-sensing' meters can be inaccurate in these situations.
Set the dial to the appropriate AC current function (e.g., `A~`). Open the jaws of the clamp meter, place them around only ONE conductor of the circuit you want to measure, and close the jaws completely. The reading will appear on the display.
Yes, this meter can measure DC current. Set the dial to the appropriate DC current function (e.g., `A-`). Open the jaws, place them around the conductor, and close them. For DC, polarity matters; the reading will show a negative sign if the current is flowing in the opposite direction through the jaws.
The `VΩmA` jack is used for measuring voltage, resistance, continuity, capacitance, frequency, diode tests, and low current. The separate current jacks are specifically for measuring higher AC or DC current and prevent blowing internal fuses.
Select the NCV function on the dial. Bring the top sensing area of the clamp meter close to the suspected live AC conductor without touching it. The meter will beep and/or flash if AC voltage is detected.
The included Type-K thermocouple typically measures from -20°C to 250°C (-4°F to 482°F). Please refer to the specific product manual for exact specifications.
Yes, the Proster Clamp Meter features overload protection on all ranges to prevent damage to the device and ensure user safety.
Ensure the test leads are properly inserted into the correct jacks and that the dial is set to the correct function. Check battery level.
Verify the dial is set to the continuity function and the resistance is very low (near zero). Ensure leads are making good contact.
Ensure the meter is powered on and the NCV function is selected. The voltage must be AC and within the detection range of the sensor.
Check if the meter is set to True RMS for non-sinusoidal waveforms. Ensure test leads are clean and making good contact. Test on a known reference if possible.
Ensure the selected range is appropriate for the expected measurement. Do not exceed the maximum rated voltage or current for the selected function.
