Fluke 114 multimeter
is basically designed for use in electric utility applications to test circuits before switching on the power at the meter. The Fluke 115 multimeter is used for electronic & electrical testing by technicians. The Fluke 116 multimeter measures temperature and microamps useful for HVAC/R technicians i.e. for heating, ventilation, Air conditioning and Refrigeration and for commercial electricians Fluke 117 came into existence. Fluke 117 multimeter is the most usable multimeter these days so in our article we are going to explain this meter in detail.

Fluke 117 Electricians Digital multimeter

Fluke 117 Electricians Digital multimeter is an ideal true RMS multimeter used for commercial applications like schools, buildings and hospitals. It prevents false readings caused by ghost voltage because of its AutoV/LoZ function & integrated non-contact voltage detection property.

Measurements using Fluke 117 digital multimeter

Fluke 117 multimeter is used for measuring various electrical parameters like Ac & dc voltage, current, resistance, capacitance, diode test etc. Check out how it measures all such parameters: Measurements

When Ghost voltage occurs in multimeters?

When energized wiring and non-energized wiring are placed very close to each other such as in a same raceway then ghost voltage occur. Due to this, capacitive coupling occurs between energized & non energized wiring and forms a capacitor. By placing the multimeter leads between the open circuit and neutral conductor, circuit get completed through the input of the meter. Internally connected capacitance, floating conductor and hot conductor form a voltage divider in conjunction with the multimeter input impedance. After this, multimeter displays the voltage value on its screen.

Why we are using AutoV/LoZ function in Fluke 117 Electricians Digital multimeter and what it designates?

For the prevention of the false readings caused by ghost voltage, Fluke 117 digital multimeter uses AutoV/LoZ function. AutoV/LoZ function of Fluke 117 is also called low impedance function. We are going to explain you what is AutoV and LoZ indicates.
(a) Auto-V (Automatic volts): With the help of this feature Fluke 117 digital multimeter easily determine whether the measured signal is ac or dc and accordingly selects the correct function, range and display right information on the screen of the meter.
(b) LoZ (low impedance): This feature provides low impedance to the input of the circuit under test. It improves the accuracy of the meter by reducing the possibility of false readings due to ghost voltages.

Advantages of Fluke 117 Electricians Digital multimeter

  1. Frequency: Measures Frequency with one tool.
  2. Analog bar graph: While monitoring measurement changes it provides better accuracy.
  3. Display Hold/Auto hold: You can easily hold your measurements for future use.
  4. Compact ergonomic design: one hand operation.
  5. VoltAlert: It has non-contact voltage detection capability i.e. there is no need for a separate detector.
  6. Large white LED backlit display: It basically make easier to read in dark locations.
  7. LoZ (low impedence input): Reduces chances of false reading due to ghost voltage.
  8. Autovolt : Without extra steps it determines Ac/Dc voltage & display voltage measurements correctly.
