Take the Measurement:</strong></p> <ol> <li data-list-indent="1" data-list-type="bulleted"> <p>Touch the probe tips of the test leads to the appropriate points on the circuit or component being measured.</p> </li> <li data-list-indent="1" data-list-type="bulleted"> <p>Observe the reading on the display. The reading will indicate the value of the parameter you are measuring.</p> </li> </ol> <p><strong>6. Interpret the Reading:</strong></p> <ol> <li data-list-indent="1" data-list-type="bulleted"> <p>Pay attention to the units displayed along with the reading, such as volts (V) for voltage, amps (A) for current, and ohms (Ω) for resistance.</p> </li> <li data-list-indent="1" data-list-type="bulleted"> <p>Consider the polarity for voltage measurements. A positive reading indicates that the red test lead is connected to the positive terminal, while a negative reading indicates that it is connected to the negative terminal.</p> </li> </ol> <p><strong>7. Disconnect the Test Leads:</strong></p> <p>Once the measurement is complete, disconnect the test leads from the circuit or component.</p> </div> </div> </div> <div class="tab-container" itemprop="mainEntity" itemscope itemtype="https://schema.org/Question"> <a href="javascript:void(0);" class="tek-basic-accordion-title" data-content="tab-A57D5DD092B04BCDA172EE70776EA1D6"> <h4 itemprop="name"> What's the difference between handheld and benchtop digital multimeters?</h4> </a> <div itemprop="acceptedAnswer" itemscope itemtype="https://schema.org/Answer" class="tek-basic-accordion-content" data-content="tab-A57D5DD092B04BCDA172EE70776EA1D6"> <div itemprop="text"> <p>Handheld digital multimeters, like those manufactured by <a href="https://www.fluke.com/">Fluke</a>, are used by electricians, electrical contractors and HVAC specialists to make measurements and troubleshoot potentially hazardous systems in the field. Benchtop multimeters, like those made by Keithley, are instruments used by electrical and electronic engineers to perform more advanced measurements and gain confidence in their designs. These instruments are extremely precise and have a variety of advanced functionality, including the ability to program automation, slow or speed up measurements to observe low-level or transient signal behavior, and interface with other instruments.</p> </div> </div> </div> <div class="tab-container" itemprop="mainEntity" itemscope itemtype="https://schema.org/Question"> <a href="javascript:void(0);" class="tek-basic-accordion-title" data-content="tab-4CBF7833508242959ACDC4F7A0F35FDD"> <h4 itemprop="name">Can Keithley digital multimeters be rack mounted?</h4> </a> <div itemprop="acceptedAnswer" itemscope itemtype="https://schema.org/Answer" class="tek-basic-accordion-content" data-content="tab-4CBF7833508242959ACDC4F7A0F35FDD"> <div itemprop="text"> <p>Yes, Keithley digital multimeters can be rack mounted with the appropriate kit.</p> </div> </div> </div> <div class="tab-container" itemprop="mainEntity" itemscope itemtype="https://schema.org/Question"> <a href="javascript:void(0);" class="tek-basic-accordion-title" data-content="tab-5ED286E8C70A4B4193B723140264C5FD"> <h4 itemprop="name">What are the safety precautions when using a digital multimeter?</h4> </a> <div itemprop="acceptedAnswer" itemscope itemtype="https://schema.org/Answer" class="tek-basic-accordion-content" data-content="tab-5ED286E8C70A4B4193B723140264C5FD"> <div itemprop="text"> <p data-pm-slice="1 3 []">When using a digital multimeter, it is important to follow safety precautions to avoid electrical hazards:</p> <ol> <li data-list-indent="1" data-list-type="numbered"> <p>Always read the user manual carefully before using the DMM.</p> </li> <li data-list-indent="1" data-list-type="numbered"> <p>Always use the appropriate voltage and current ranges for the circuit you are measuring.</p> </li> <li data-list-indent="1" data-list-type="numbered"> <p>Never touch exposed wires or components while the DMM is connected to a circuit.</p> </li> <li data-list-indent="1" data-list-type="numbered"> <p>Always work in a well-lit and ventilated area.</p> </li> <li data-list-indent="1" data-list-type="numbered"> <p>Wear proper personal protective equipment (PPE), such as safety glasses and gloves, when working with electrical circuits.</p> </li> <li data-list-indent="1" data-list-type="numbered"> <p>Never use a DMM that is damaged or malfunctioning.</p> </li> </ol> </div> </div> </div> </div> </div> </div> </main> <footer class="footer footer-redesign"> <div class="container"> <div class="footer-logo"> <picture><img src="/patternlab/images/transparent-pixel.png" alt="Tektronix" data-src="/-/media/project/tek/images/logos/tek-monogram/logo_tk_footer.svg?iar=0" class="lazy"></picture> </div> <div class="footer-about"> <p class="heading">About Tektronix</p> <p class="about"> We are the measurement insight company committed to performance, and compelled by possibilities.
