Fluke 福禄克 FLUKE 289/EUR 数字电流表

Fluke 280 Series high performance multimeters are designed to meet demanding applications. The Fluke 287 is optimised for R & D, maintenance, manufacture and design of electronic circuits or systems. The Fluke 289 is optimised for industrial and field service professionals involved in the installation and maintenance or support of facilities or critical systems.50 000 Count, 320 x 240 dot-matrix LCD display with white backlight, allowing clear multiple on-screen display of measurement information. 0.025% basic DC accuracy. Logging function with TrendCapture plots measurements as single line to help detect anomalies (TrendCapture allows graphically view of logged readings without a PC). F1 â†' F4 soft keys provide flexible user function menus. Navigation keys allow quick selection of menu options and scroll through information screens. Saved measurements allow operator to name and recall measurements made in the field. Upgradeable field and expandable meter as new capabilities are added. Record events and trends for troubleshooting intermittent problems or profiling loads. i-info button on-board helps screen for measurement functions. Internal memory allows standalone logging for up to 180 hours. Preferred measurement settings can be easily saved. True RMS AC voltage and current for accurate measurement of complex signals or non-linear loads. AC bandwidth specified to 100 kHz. DBV \/ dBm measurement. 1 μV resolution in DC mV range. Current measurement 20 A (30 seconds momentary, 10 A continuous). Peak capture function to record transients as fast as 250 μs. Continuity \/ Conductance \/ Capacitance. Resistance and continuity. Duty cycle & pulse width measurement. Min \/ Max \/ Average with Time Stamp to record signal fluctuations. Real time and elapsed time modes. CAT III 1000 V \/ CAT IV 600 V safety ratedLoZ low input impedance function helps prevent false readings due to ‘ghost voltage’. 50 Ω range for motor winding and low ohm measurements. Low pass filter allows for accurate measurements of motor drives. Optical USB PC communication interface allows for easy PC download to document logged data with FVF software, available separatelyMultimeter Type = HandheldAbsolute Maximum AC Current Measurement = 10A acAbsolute Maximum DC Current Measurement = 10A dcAbsolute Maximum Resistance Measurement = 500MOhmsAbsolute Maximum DC Voltage Measurement = 1000V dcAbsolute Maximum AC Voltage Measurement = 1000V acAbsolute Maximum Capacitance Measurement = 100mFAbsolute Maximum Temperature Measurement = +1350°CFunctions Measured = AC Current, AC Voltage, Capacitance, Continuity, DC Current, DC Voltage, Resistance, TemperatureTrue RMS = Yes
