Fluke digital multimeter basics final exam answers

Test is useful connect the probe ends. Together the meter display should read a small ohms value of

What does 6000 counts mean on a multimeter?

Generally 6000 Count Multimeter have range 600.0 mV, 6.000 V, 60.00 V, 600.0 V. The count refers to the limit of the highest value the Multimeter will display for each range.

How accurate is a Fluke multimeter?

Use of a digital multimeter with higher accuracy allows for a great number of applications. Basic dc accuracy of Fluke handheld digital multimeters ranges from 0.5% to 0.025%.

How do you reset a Fluke multimeter?

HOW TO CALIBRATE A FLUKE MULTIMETER

Hold the Min/Max button down while turning the rotary know to the “VAC” position.
Press the Auto/Hold button again. ...
When “C-01” displays on the screen, attach the outputs from the meter to the inputs on your electric calibrator.

What are the symbols on a Fluke multimeter?

This guide will take you through the basic anatomy of a digital multimeter. ... Digital multimeter jacks

A (amps)
mA, μA (milliamps, microamps) ...
COM. ...
Voltage (V), resistance (Ω), diode test (arrow plus symbol), capacitance (other symbol), temperature.

How is voltage fluke measured?

Simply move the dial position to measure current and now you can slide your open jaw design around

What is the range of ohms?

Most resistors you'll see range between 1 ohm and 1 megaohm (1.0 MΩ) they often have 5% tolerance but you can buy 1% or even 0.1% accuracy resistors. In general, resistence testing is best for measuring resistors, but you may find yourself measuring the resistance of other things, such as sensors and speakers.

What does K stand for on multimeter?

The sub-units are as follows – K for kilo, which means 1000 times. M for mega or million, which means 10,00,000 times. m for milli, which means 1/1000. (µ) for micro, which means 1/million.

What is the unit of multimeter?

A multimeter or a multitester, also known as a volt/ohm meter or VOM, is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter may include features such as the ability to measure voltage, current and resistance.

Why are Fluke multimeters so expensive?

The reason they're so expensive is four reasons: 1. Mains and high voltage work. If you're working with high voltages or massively different potentials, Fluke actually design the boards and isolation circuitry properly.

What does a 4 ½ digit display mean?

A half digit can only represent a “1”, but a 2 can no longer represent a whole digit. This means a 4-digit ½ display can show values from 0 to 19999. A 4-digit display, on the other hand, can only show values from 0 to 9999.

What does 1 digit accuracy mean?

One digit is the minimum value that can be displayed, which is the resolution in the measuring instrument (the µR series). In the 2 V range, 1 digit = 0.001 V (1 mV). <Calculation example> Calculate the measurement accuracy when measuring 2 V in the 2 V range.

What does OL mean on a Fluke multimeter?

Infinite resistance (open circuit) is read as “OL” on the Fluke meter display, and means the resistance is greater than the meter can measure. Resistance measurements must be made with the circuit power off – otherwise, the meter or circuit could be damaged.

How does a Fluke multimeter measure DC current?

Connect the test probes to the circuit: black to the negative polarity test point (circuit ground), red to positive test point. ... Other useful functions when measuring dc voltage

Disconnect the test probes.
Change the dial setting to dc millivolts.
Reconnect the test probes and read the measurement.

Can you calibrate a fluke meter?

Hold down the "Min/Max" button on the meter. While holding this button down, turn the rotary knob to the "VAC" position. You will see "CAL" appear on the display to indicate that you have entered calibration mode. You can now release the "Min/Max" button safely.

What are the 4 function of multimeter?

Simple budget models have a small set of functions that are sufficient for solving basic common tasks: checking the conductors, continuity of the circuit, measuring the voltage in the socket or the battery level of the car. The set of additional functions of the multimeter depends on the purpose of the instrument.

How is DC current measured?

Both AC and DC currents can be measured with a multimeter by connecting the meter in series with the circuit, in which the current is measured provided the current in that circuit is limited or controlled by a load or appropriate values of resistance.

What is the symbol for DC voltage?

To signify DC voltage, the convention is to place a dotted line with a solid line above it over the V. To get voltage readings in millivolts (one-thousandth of a volt), set the dial to mV. “V” with a wavy line over it = AC voltage. “V” with one dotted and one solid over it = DC voltage.

What is the range of DC voltage?

There are a variety of DC voltage levels, typical values are 1.2, 1.5, 3, 3.3, 3.6, 5, 6, 10, 12, 15, 18, 18.5, 19, 20, 24, and 48 Volts.

What is a ghost voltage?

As you may know, ghost voltages occur when your test (which isn't receiving power) reads voltage from a nearby electrical source. Usually, this is due to extra and unused wiring in the conduit being tested as it runs along other wires that are receiving power.
