True RMS AutoSensingTM Multimeter MN30 NCV
The MN30 is a manual range multimeter that measures resistance, frequency, capacitance, temperature, duty cycle, and diode test in addition to AC/DC voltage and current. Additionally, it has an integrated non-contact voltage detector for speedy live circuit detection.
The MN30’s AutoSensingTM feature, which automatically chooses whether to monitor AC or DC voltage, is one of its key features.
This might help you save time and effort while analysing various voltage sources. There is no need to turn the dial or touch any buttons. To read the display, simply connect the test leads.
The MN30 also has a True RMS function, which can accurately interpret waveforms that are loud or distorted. This is significant when gauging the AC voltage or current coming from variable frequency drives, inverters, or other non-sinusoidal waveform-generating electronic devices.
The MN30 has a large LCD screen with backlighting and a bar graph that displays the measurement’s relative value.
Additionally, it has a data hold feature that freezes the display to make reading it easier. It includes an impact- and drop-resistant rubber holster for protection. Additionally, it has a tilt stand so you can set it down on a flat surface and operate it without using your hands.
Among the benefits of the MN30 are:
A wide range of electrical properties can be measured, and it can also detect live circuits without making contact.
It contains an AutoSensingTM capability that chooses the AC or DC voltage measurement automatically.
Its True RMS feature can deliver precise readings of distorted or noisy waveforms.
It has a sizable LCD screen with a backlight and a bar graph that displays the measurement’s relative value.
It is strong and simple to use because it has a tilt stand and a protective rubber holster.
The following are a few MN30 drawbacks:
It is a manual ranging multimeter, therefore in order to measure anything other than voltage, you must choose the proper range.
It doesn’t measure continuity or AC current.
It lacks an automatic power-off feature that might extend battery life.
The MN30 costs roughly $60 and includes a user guide, test leads, a type K temperature probe, and a 9V battery.
Here are some pointers and strategies for using the MN30:
Set the dial to V and attach the test leads to the COM and V//CAP terminals to activate the AutoSensingTM feature. The voltage is automatically detected by the metre, which then shows it on the screen.
Press the NCV button on the meter’s top to activate the non-contact voltage detector. Look for an audible and visible indicator on the screen when holding the metre close to a live circuit. As you approach the live circuit, the indicator will turn from green to red.
Press the TRMS button on the front panel to activate the True RMS feature. On the screen, the TRMS sign will show. Only measurements of AC voltage or current are compatible with this function.
Press the HOLD button on the front panel to activate the data hold feature. The display will freeze and the HOLD symbol will appear on it. To release it, press the HOLD button one again.
The digital mini multimeter MN15A
The MN15A is a small manual range multimeter that measures resistance, temperature, diode testing, AC/DC voltage, DC current, and other quantities. It boasts a sizable, simple-to-read digital display as well as a tilt-able, protective rubber holster.
The MN15A’s battery test function, which allows you to easily assess the health of 1.5V and 9V batteries, is one of its key features. All that is required is to connect the test leads to the COM and BAT terminals and set the dial to BAT. The battery life left in percentage will be shown on the metre.
The MN15A also has a temperature function that uses a type K thermocouple probe to measure surface and air temperatures. All that is required is to connect the test leads to the COM and TEMP terminals and set the dial to TEMP. The temperature will be shown on the metre in either Celsius or Fahrenheit.
The 2000 count LCD display of the MN15A provides clear and precise readings. Additionally, it has a data hold feature that freezes the display to make reading it easier. It includes an impact- and drop-resistant rubber holster for protection.
