Today, both analog and digital double clamp phase voltmeters are widely used and are indispensable to anyone working in the electronic or electrical field. This is an essential tool for troubleshooting circuits. It's not just electricians who need digital double clamp phase voltmeters. Contractors, handy people, homeowners and anyone doing electrical work around the house should have someone to diagnose problems and test the circuits. Digital dual clamp phase voltmeters are also essential for diagnosing equipment failures, testing automotive circuits and other purposes.

Why is a digital double clamp phase voltmeter needed

If you work in the electronics industry or as an electrician, there is no need to tell you why you need a digital dual clamp phase voltmeter. However, if you are a homeowner or a handy person, you may not use electrical measuring equipment on a daily basis, and the need for such equipment may not be immediately apparent. But put the digital dual clamp phase voltmeter in the tool cabinet and you'll be surprised at how often it's used. Digital dual clamp phase voltmeters are useful in the following situations:

• Test socket: When the device does not seem to be working properly, you can set the digital dual clamp phase voltmeter to the test voltage and then insert the wire into the socket socket. If the digital dual clamp phase voltmeter does not show voltage at all, you are experiencing a circuit problem that prevents current from flowing. Alternatively, you may find that moving the probe causes the meter to throb, which means you need to replace the socket. On the other hand, you might get a voltage reading, but much smaller than the actual reading, indicating that a circuit defect requires attention.

• Electrical maintenance: Modern appliances are full of sensitive circuit elements and can go bad. Digital dual clamp phase voltmeters are the preferred tool for zeroing out problematic components in the event of equipment failure.

• Test batteries and bulbs: Filled with old batteries or incandescent bulbs? Test the battery using the voltmeter function to determine which batteries are good and which should be discarded. Set up meter to measure continuity or resistance to test bulb. Infinite resistance or negative continuity results mean the bulb is bad.

• Test switch: If you think the switch is not good, you can test it using the ohmmeter function on the digital dual clamp phase voltmeter. Close the circuit breaker and disconnect the switch, then set the meter to measure resistance A and touch the probe to the switch terminal. When the switch is off, the resistance should be close to zero. If the resistance is very high, it's time for a new switch.

An ohmmeter or continuity tester is an excellent tool for diagnosing a thermostat that doesn't work properly. To test the resistance, please hold the wire at the same port (public ports and V Ω), and set the dial to resistance. You will get the units of ohms (Ω) reading. If you are using a digital model and the screen shows OL (null line), the infinite resistance reading on the analog meter is the same. If the meter is continuous and you select it, the buzzer will not go off because there is no continuity.

The digital dual clamp phase voltammeter is useful for measuring current amperes when you are building or diagnosing electronic circuits. Change the red probe to an ampere (A) or mA/Microampere (mA/A) port and set the dial to the appropriate sensitivity. Testing electronic circuits requires extra care, as you often need to measure direct current rather than alternating current. In addition, if the selection is too sensitive, the instrument's built-in fuse may blow. If this happens, the meter will not work until the fuse is replaced.
