measurement performance depends on the selected range, frequency and signal characteristics.<\/p>\n<p>This functionality is useful for evaluating electrical loads, electronic circuits and industrial measurement systems.<\/p>\n<h2>Precision Resistance Measurement<\/h2>\n<p>The Fluke Calibration 8845A provides accurate resistance measurement.<\/p>\n<p>The available resistance ranges extend from:<\/p>\n<p><strong>100 \u03a9 to 100 M\u03a9<\/strong><\/p>\n<p>The maximum resolution is:<\/p>\n<p><strong>100 \u00b5\u03a9<\/strong><\/p>\n<p>The manufacturer specifies a basic resistance

significant.<\/p>\n<p>The Fluke Calibration 8845A provides a special measurement function to reduce these effects.<\/p>\n<h2>Patented 2 \u00d7 4-Wire Resistance Measurement<\/h2>\n<p>The Fluke Calibration 8845A features patented 2 \u00d7 4-wire resistance measurement technology.<\/p>\n<p>This function allows four-wire resistance measurements to be performed using only two specially designed test leads.<\/p>\n<p>Conventional four-wire resistance measurements require separate connections for current supply and voltage measurement.<\/p>\n<p>The 2 \u00d7 4-wire technique combines these connections in specially designed split-terminal connectors.<\/p>\n<p>This simplifies precision resistance measurement while retaining the advantages of four-wire measurement.<\/p>\n<p>Compatible Kelvin test leads are available as accessories.<\/p>\n<p>The function is particularly useful when measuring low-value resistors and components with limited connection space.<\/p>\n<h2>Frequency and Period Measurement<\/h2>\n<p>The Fluke Calibration 8845A includes frequency and period measurement functions.<\/p>\n<p>The frequency measurement range extends from:<\/p>\n<p><strong>3 Hz to 300 kHz<\/strong><\/p>\n<p>The manufacturer specifies a frequency measurement accuracy of:<\/p>\n<p><strong>0.01%<\/strong><\/p>\n<p>The maximum frequency resolution is:<\/p>\n<p><strong>1 \u00b5Hz<\/strong><\/p>\n<p>These functions allow the instrument to measure the frequency and period of suitable electrical signals.<\/p>\n<p>Typical applications include:<\/p>\n<ul>\n<li>Signal generator verification<\/li>\n<li>Electronic oscillator testing<\/li>\n<li>Frequency measurement<\/li>\n<li>Industrial signal analysis<\/li>\n<li>Electronic circuit development<\/li>\n<\/ul>\n<p>The applicable measurement conditions and signal requirements must be considered.<\/p>\n<h2>Dual Measurement Display<\/h2>\n<p>The Fluke Calibration 8845A features a dual measurement display.<\/p>\n<p>This allows two measurement parameters associated with the same input signal to be displayed simultaneously.<\/p>\n<p>For example, the instrument can display AC voltage and frequency at the same time.<\/p>\n<p>This eliminates the need to switch repeatedly between measurement functions.<\/p>\n<p>The dual display is particularly useful when evaluating signals with several relevant characteristics.<\/p>\n<p>It also simplifies measurement procedures in laboratories and automated test environments.<\/p>\n<h2>Graphical TrendPlot Function<\/h2>\n<p>The Fluke Calibration 8845A includes an integrated TrendPlot function.<\/p>\n<p>TrendPlot allows measurement values to be displayed graphically over time.<\/p>\n<p>This makes it easier to identify:<\/p>\n<ul>\n<li>Measurement drift<\/li>\n<li>Signal instability<\/li>\n<li>Intermittent faults<\/li>\n<li>Slow changes in electrical quantities<\/li>\n<li>Unexpected measurement variations<\/li>\n<\/ul>\n<p>The function acts as a paperless graphical recorder.<\/p>\n<p>It is particularly useful when investigating long-term signal behavior.<\/p>\n<p>For example, the stability of a voltage source can be monitored without requiring a separate chart recorder.<\/p>\n<h2>Histogram Function<\/h2>\n<p>The Fluke Calibration 8845A includes a histogram display.<\/p>\n<p>A histogram shows the distribution of recorded measurement values.<\/p>\n<p>This helps users evaluate the variation and stability of an electrical signal.<\/p>\n<p>A narrow distribution indicates relatively small measurement variation.<\/p>\n<p>A wider distribution may indicate increased noise or instability.<\/p>\n<p>Histogram analysis is useful for evaluating measurement repeatability and identifying unexpected fluctuations.<\/p>\n<p>The function provides additional information that cannot be obtained from a single displayed measurement value.<\/p>\n<h2>Statistical Measurement Functions<\/h2>\n<p>The Fluke Calibration 8845A includes integrated statistical functions.<\/p>\n<p>Available functions include:<\/p>\n<ul>\n<li>Minimum value<\/li>\n<li>Maximum value<\/li>\n<li>Average value<\/li>\n<li>Standard deviation<\/li>\n<\/ul>\n<p>These functions help users evaluate a series of measurement values.<\/p>\n<p>Statistical analysis is particularly useful for investigating signal stability and measurement repeatability.<\/p>\n<p>The standard deviation provides information about the dispersion of recorded values.<\/p>\n<p>For calibration applications, statistical results can support the evaluation of repeatability.<\/p>\n<p>However, the complete measurement uncertainty must also include other relevant uncertainty contributions.<\/p>\n<h2>dB and dBm Measurement<\/h2>\n<p>The Fluke Calibration 8845A supports dB and dBm calculations.<\/p>\n<p>These functions are useful when evaluating electrical signal levels.<\/p>\n<p>The dB function expresses a ratio between two values on a logarithmic scale.<\/p>\n<p>The dBm function expresses electrical power relative to 1 mW, based on the configured reference impedance.<\/p>\n<p>These functions simplify measurements in electronic development and signal analysis.<\/p>\n<h2>Continuity and Diode Testing<\/h2>\n<p>The Fluke Calibration 8845A provides continuity and diode test functions.<\/p>\n<p>Continuity testing is useful for checking electrical connections and detecting open circuits.<\/p>\n<p>Diode testing allows the forward voltage of semiconductor junctions to be evaluated.<\/p>\n<p>These functions make the instrument suitable for general electronic troubleshooting in addition to precision electrical measurements.<\/p>\n<h2>Front and Rear Measurement Terminals<\/h2>\n<p>The Fluke Calibration 8845A features measurement terminals on the front and rear panels.<\/p>\n<p>This provides additional flexibility when integrating the instrument into a measurement system.<\/p>\n<p>Front terminals are convenient for manual measurements.<\/p>\n<p>Rear terminals are particularly useful for permanently installed measurement setups and automated test systems.<\/p>\n<p>The selected terminal configuration must be appropriate for the measurement application.<\/p>\n<h2>RS-232, IEEE-488 and Ethernet Interfaces<\/h2>\n<p>The Fluke Calibration 8845A provides several communication interfaces.<\/p>\n<p>These include:<\/p>\n<ul>\n<li>RS-232<\/li>\n<li>IEEE-488<\/li>\n<li>Ethernet<\/li>\n<\/ul>\n<p>The instrument supports SCPI commands for remote operation.<\/p>\n<p>It also provides compatibility modes for certain older measurement instruments.<\/p>\n<p>These capabilities make the Fluke Calibration 8845A suitable for integration into automated test environments.<\/p>\n<p>Computer-controlled measurements can improve efficiency and repeatability.<\/p>\n<h2>Integration into Automated Calibration Systems<\/h2>\n<p>The Fluke Calibration 8845A is suitable for automated electrical measurement applications.<\/p>\n<p>Its communication interfaces allow measurement functions and settings to be controlled remotely.<\/p>\n<p>Measurement values can be transferred to compatible software systems for evaluation and documentation.<\/p>\n<p>Typical applications include automated production testing, calibration procedures and laboratory measurement systems.<\/p>\n<p>The instrument can also be integrated into suitable MET\/CAL-based workflows when supported by the applicable procedure and communication configuration.<\/p>\n<p>The availability of a compatible instrument driver or procedure must be checked separately.<\/p>\n<h2>Technical Highlights<\/h2>\n<table>\n<tbody>\n<tr>\n<th>Specification<\/th>\n<th>Fluke Calibration 8845A<\/th>\n<\/tr>\n<tr>\n<td>Manufacturer<\/td>\n<td>Fluke
