Attention: Please check the box for 110V grid voltage: Flat plug (US standard) 199V. For example, Taiwan, China, the United States, Canada, Panama, Cuba, Lebanon, Mexico [Japan and North Korea 100V voltage] [because the error is small when measuring 110V grid voltage with 199V]
1: AC80-300V [220V grid voltage usage]
2: AC80-199V [110V grid voltage usage]
Overview:
Plug type digital voltmeter (pen type voltmeter) is widely used for detecting AC AC 80-199V-300V mains voltage (real-time monitoring of the current grid voltage). Simply plug the voltmeter into the plug board or wall switch to immediately display the current voltage (whether it is in a home, office, industrial and mining enterprise, etc.). The biggest advantage is that when you see the current grid voltage is too low or too high, It is possible to selectively turn off the operation of a certain household appliance or device (especially low voltage household appliances such as air conditioners, refrigerators, etc.), effectively protecting the service life of your household appliances and devices (and can also be used as a simple electric measuring pen). There are two types of instruments: flat plug and European plug (as shown in the figure below), and European plug is generally exported to European countries and the Middle East region. (Note: 1200 hours consume 1 kWh of electricity)
