2. Data Hold and Auto Power Off: The data hold function allows you to hold the last measured value, while the auto power off feature saves battery life by turning off the device after a period of inactivity.
3. Backlight and Large Display: The device has a backlit LCD display that is easy to read in low light conditions, and it's large enough to clearly display the readings.
4. Safety Features: The Metex M-3900 has overload protection, short circuit protection, and diode test function to ensure safety during use.
Cons of Metex M-3900 Digital Multimeter T/D Tester:1. Limited Frequency Range: The frequency range of this multimeter is only up to 100 kHz, which might not be sufficient for some high-frequency applications.
2. No True RMS Function: The device does not have a true RMS function, which may lead to inaccurate readings when measuring AC signals with non-sinusoidal waveforms.
3. No Probe Protection: The probes do not have any protection against overvoltage or overcurrent, which could potentially damage the device or the user.
Ending Conclusion:The Metex M-3900 Digital Multimeter T/D Tester is a decent tool for basic electrical measurements and temperature readings. Its wide range of measurements, data hold, and auto power off features are useful. However, its limited frequency range and lack of true RMS function and probe protection are drawbacks that should be considered before making a purchase. If these features are not essential for your needs, then the Metex M-3900 could be a good choice due to its affordable price.
Recommendation:If you're looking for a multi-purpose digital multimeter with temperature measurement capabilities, the Metex M-3900 could be a suitable option. However, if you require a device with a wide frequency range or true RMS function, you may want to consider other models that offer these features. Always ensure to use the device safely and follow the manufacturer's instructions to avoid any potential damage or injury.
