5 / 18 page 05 | Keysight | U1280 Series Handheld Digital Multimeters - Data Sheet Figure 6. Data logging experience with Keysight Meter Logger software Figure 5. Hold & Export button—one press for three actions: Measure, save it into handheld DMM’s memory and send the measurement out via infrared port. Optional U5404A remote switch probe emulates ‘Hold & Export’ button. Figure 7. Pair up the U1280 series with Keysight Remote Link solution for wireless measurement option Manual logging made easy with Hold & Export button While data logging over a period of time is useful to capture measurements for further observations and analysis, manual data log is just as useful to conveniently record measurements and reduce human error occurrence from conventional manual data entering process. Better yet, users are able to store measurement readings into the handheld DMM’s internal memory and at the same time export the measurements to the Keysight Meter Logger software or Keysight Remote Link solution via the DMM’s infrared port — all of these by simply pressing the ‘Hold & Export’ button. When the situation requires users to concentrate on probing, the optional U5404A remote switch probe can be used to perform manual logging by emulating the ‘Hold & Export’ button of the U1280 Series handheld DMMs. Built-in low pass filter Today, three-phase AC electric motors are the most important workhorses in industry and commercial facilities. With the advent of solid state electronics, variable speed drives (VFD) are used to regulate the speed of three-phase AC motors to increase the effi- ciency of AC motors. However, the increased use of VFDs present challenges to technicians in getting accurate voltage, current and frequency measurements that match with readings shown on the VFD’s control panel display. Many true RMS DMMs that have high AC bandwidth are measuring VFD signals up to 20% to 30% higher than the drive’s controller display due to the reason that DMMs are measuring the carrier frequency/switching frequency generated by VFDs. Keysight U1280 Series comes with LPF (low pass filter) feature which blocks unwanted high frequency signal from VFDs’ switching components. The net result is an accurate measurement of VFD’s output signal which helps to expedite the maintenance or troubleshooting tasks of VFDs. Programmable Keysight U1280 Series comes with programmability capability that allows avid programmer to create computer programs to control the handheld DMM. The programmability of Keysight U1280 Series allows users to automate Keysight U1280 Series or even integrate into bigger test systems. |
