This digital multimeter is auto-ranging and features a large rotary knob for easy selection of the required test. For people who want to check that their Earthing Product is actually working.
There are two additional buttons, one to lock the range and the other to hold the result on the display. The multimeter functions include DC Volts, AC Volts, AC Amps, Ohms, Continuity with Audible Indication and Diode Test.
To check Body Voltage ground the Black Lead (to earthed radiator or Earthing Product or Ground Plug connected to mains outlet) and hold the Red Lead Pin between finger and thumb, or place it on bare skin on the body. Take a reading while not Earthed. You may need to adjust the AC Voltage Range by pressing the Range Button to obtain a reading depending on level of body voltage. Then test again while feet are on the Earthing Product to see how much your Body Voltage has been reduced. Using an Earthing Mat for example, hold the Red Lead Pin with on ehand and place the Balck Lead Pin on the Earthing Mat, and you should see the AC Voltage reading drop into the low mV and to even 10ths of a mV, depending on external AC and Wi-Fi influences. Can also be used to give an idea of the Resistance (therefore conductivity) of the Earthing Product and Ground Leads used. Full instructions provided.
Each digital multimeter is supplied with standard test leads, batteries, protective rubber holster and instruction manual. 2 year Warranty inside.
