12 best volt meters

A voltmeter is an essential electrical instrument used to measure the electrical potential difference, or voltage, between two points in an electrical circuit.Here's what you should know about voltmeters:

Purpose: Voltmeters are designed to measure voltage, which is the force that drives the flow of electric current in a circuit. They help electricians and technicians assess the voltage level at various points within an electrical system.
Types of Voltmeters:
- Analog Voltmeters: These meters use a pointer or needle to display the voltage reading on a scale. They are considered traditional and are less common in modern applications.
- Digital Voltmeters (DVMs): Digital voltmeters provide a numerical readout of the voltage, making them more precise and easier to read. They are widely used in both professional and DIY applications.
Ranges: Voltmeters come in a variety of voltage ranges, from millivolts (mV) to kilovolts (kV). The range you select depends on the specific voltage you need to measure.
AC and DC Voltmeters: Some voltmeters are designed to measure either AC (Alternating Current) or DC (Direct Current) voltage, while others are capable of measuring both. It's crucial to use the right type for the electrical system you are working on.
Input Impedance: A voltmeter should ideally have high input impedance, as this minimizes the impact of the meter on the circuit being measured. High input impedance voltmeters do not draw much current from the circuit under test, ensuring accurate readings.
Safety: When using a voltmeter, it's important to ensure your safety and the safety of the equipment. Make sure the voltmeter is rated for the voltage you intend to measure, and take precautions to avoid electrical shocks.
Probe Selection: Voltmeters typically come with probes, which are used to make contact with the electrical points under measurement. The choice of probe, such as needle-point or alligator clips, depends on the application and the accessibility of the points.
Usage: To measure voltage with a voltmeter, you typically set the meter to the appropriate voltage range, connect the probes to the points you want to measure, and read the displayed value. Be mindful of polarity in DC circuits, as reversing the probe connections can result in a negative reading.
Applications: Voltmeters are used in various applications, including troubleshooting electrical problems, testing batteries, assessing power supplies, and monitoring voltage levels in electrical equipment.
Calibration: Periodic calibration and maintenance are essential to ensure the accuracy of voltmeters. Some devices may need regular recalibration to maintain their precision.

In summary, voltmeters are indispensable tools in the field of electrical engineering and maintenance, allowing professionals and enthusiasts to measure voltage accurately, diagnose electrical issues, and maintain the proper functioning of electrical systems.

User questions & answers

Question:	Hi, Is there a protection plan options for this item? if yes, what's the cost of the plan. Thanks
Answer:	Why bother, the cost is low and there is a return policy.
Question:	is the a category 3 and true RMS meter
Answer:	NO
Question:	Is your meter made here in the usa,or is it out sourced from china
Answer:	Of course in China , as almost tech gadget, it would have costed at least 10 times more if made in USA, and not any better
Question:	Does this work with square waves like those for the output of a 12V landscape lighting transformer? If so, what setting should be used
Answer:	A square wave can be expressed as a sum of the fundamental frequency and many harmonics, the meter is designed to measure just the fundamental , 60 hz, if it can do a proper filtration of it, which is pretty difficult, so NO

Power Probe IV

Available Colors:

PP401AS - Red

PP405AS - Green

Fuel Injector Test

FUEL INJ = Fuel Injector Mode is specifically set-up for fast and easy injector circuit diagnosis. One quick connection to the circuit and the Power Probe IV will display all the needed fuel injector testing information that would normally require using an lab-scope.

Fuel Injector Test (Continued)

ON- ms = Injector Pulse On-Time (milliseconds) - This is the total amount of time that the fuel injector is energized and supplying fuel to the cylinder. This can be compared to scan tool PID data to see if commanded on-time equals actual on-time.

2 IND-K V = Inductive Kick Voltage - Normal inductive kicks range between 55 and 90 volts. You should see a similar voltage number from each of injectors on the engine. Note: The height of the inductive kick is sometimes cut-off by an internal ECM diode to about 35 to 45 volts. Note: This test does not apply to hi-pressure injectors used on diesel engines and gasoline direct-injection en- gines.

3 ECM V = ECM Ground Voltage - The engine computer activates each fuel injector by com- pleting the ground circuit with an internal transistor switch. When the fuel injector is energized, the ECM ground voltage should be close to zero volts. Actual measured ECM ground voltage can vary, and may be closer to 0.5 volts because of the internal resistance of the switching transistor.

4 INJ V = Injector Supply Voltage - This is the battery power being supplied through the fuel injector itself. Measured voltage should be close to full battery voltage. There may be small volt- age drops in the circuit, however, anything more than 0.5 volt loss from the source battery voltage should be investigated.

Feed Test

FEED TEST - Power Feed Test (PFT) is a powerful feature primarily intended for testing power or ground feeds. PFT places a small current load (30 milliamps).

on the circuit and will safely load circuits during voltage and ground testing, while at the same time providing an accurate resistance reading of the circuit you are testing.

Loading the circuit provides more reliable data and can quickly identify circuit weakness caused by damaged or corroded wiring or connectors that normally can’t be found using a static voltage check.

Voltage Test

VDC mode is for testing DC (direct current) voltages. Voltage testing is as easy as contacting the probe tip to a circuit and reading the display. The Power Probe IV will display the probe tip voltage in the center display.

The Power Probe IV automatically enters VDC Mode when first connected to the vehicle’s battery, or to a 12-24 volt power supply. VDC Mode is the only mode that the Power Probe IV can supply battery power or ground by pressing the rocker switch.

If the Probe tip voltage is within 0.5 volts of the source battery voltage and the circuit resistance is less than 10 Ohms, the Red LED will illuminate and if the speaker is turned on, the speaker will make a high-tone.

When testing on ground circuits, as long as there is less than 10 Ohms total circuit resistance from tip to battery ground, the Green LED will illuminate and the speaker will make a low-tone.

User questions & answers

Question:	Would you choose this model or another for automotive diagnosing
Answer:	To answer your question I'm a master Automotive technician most of the people in the business use flukes but our use these ones because they are accurate and work just as good as the fluke when it comes to Automotive Diagnostics. There is nothing you can't do with this digital multimeter that you can do with a fluke
Question:	I have been trying to measure the ac/dc amps with this but doesn't work. i wanted to know if i am missing something or its actually faulty
Answer:	Make sure you have the leads in the proper slots or ports for the amperage reading.
Question:	What does "4000 counts" mean
Answer:	Counts and digits are terms used to describe a digital multimeter's resolution. Today it is more common to classify digital multimeters by the total counts than by digits. Counts: A digital multimeter resolution is also specified in counts. Higher counts provide better resolution for certain measurements.
Question:	Do the Battery Test selections test under load
Answer:	battery test 1.5v 30 ohm load 9v-12v 300 ohms load
