Fortune Multimeter Special Function Application
Analogue Pointer Just like the pointer of an analogue meter, but without over-range, the display is updated more quickly and is very convenient for maximum and zero calibration and for observing rapidly changing signals, and is widely used for quick judgement of voltages, currents, resistances and capacitances.
Data Hold/Trigger Hold/Update Hold (HOLD) The data hold function allows the operator to freeze the displayed value, while the analogue pointer meter does not have this function. Trigger Hold is a HOLD key operation on top of Data Hold to display an updated measured value. Update Hold can be enabled in Setup Mode (default is Trigger Hold), this function automatically triggers or updates the hold value with a new measured value and sounds an audible alert. The meter will hold the new measured value once the measured value has changed beyond the setup error range. Very suitable for difficult environments.
III.Dynamic Recording (Max/Min/Ave) Dynamic recording mode is used to capture surges that occur during intermittent switching on or off, or when you are operating equipment and cannot take a reading, then the meter can record the data. Average readings are used to filter out unstable or varying inputs, to estimate the percentage of time to operate a circuit or to calibrate the performance of a circuit. And the ESCORT-279/278 also has a (Max-Min) display to read peak-to-peak values.
Relative Zeroing REL Relative Zeroing function subtracts a stored value from the current value and displays the result of the subtraction When making resistance measurements, the display value is non-zero due to the influence of the test pens, so use the Relative Zeroing function to zero the current display. DC voltage measurement, due to the thermal effect of the impact of the display is not zero, short-circuit the test pen, use the relative function to zero the thermal effect.
V. 1ms Peak Hold This function can be used to analyse components such as power distribution transformers and power factor correction capacitors. By using the 1ms peak hold function of the ESCORT-99/98, its peak factor can be calculated. Peak Factor = Peak/True RMS
VI.FREQUENCY MEASUREMENT Frequency measurement helps to check the presence of harmonic currents in the neutral conductor and to determine whether these neutral currents are caused by unbalanced phases or non-linear loads.ESCORT-172 up to 34MHz is the frequency measurement of your choice.
VII. Harmonic Ratio Measurement The harmonic ratio function is a calculated value on a bias between 0% and 100% and is a parameter that characterises harmonics. A sine wave that is purely free of harmonics has a harmonic ratio of 0%, higher harmonic ratios mean that there are more harmonics in the signal. This function is used for simple power quality analysis without the need to purchase expensive professional test equipment.
Eight, dBm / dBV test dBm and dBV is often used to characterise the relative power value of the signal and the relative voltage value, the formula is: dBm = 10lgP (power value / 1mw). Commonly used in some amplification circuits, such as audio, speakers and other electro-acoustic field tests.
Nine, transistor DC amplification HFE As the name suggests, this function is used to test the DC amplification of transistors, an ESCORT-168A multimeter that solves your needs.
