| DranTech ULTRA - Precision Digital Multimeter The ULTRA multimeter is a high performance, precision measuring instrument for R&D labs, industrial applications, universities, government authorities, testing stations, manufacturing and QA. With a display range of 1,200,000, as well as exceptional accuracy and long-term stability, it fulfills all of the demands of calibration and R&D labs. Features True RMS Measurement of Distorted Waveforms The measuring method applied allows for waveform independent RMS measurement for voltage and current up to 100 kHz at crest factors of up to 10. Sampling Rate The sampling rate determines the interval at which the respective measurement value is saved to memory. Depending upon measured quantity and resolution, the interval can be set within a range of 0.01 s to 60 s. Storing MIN-MAX Values to Memory In addition to displaying the current measurement value, the minimum or maximum value can be continuously updated and stored to memory at the selected sampling rate. Memory Mode The instrument is equipped with a 128 kB data memory with backup battery. The memory can be devided in 1 to 15 blocks. New values can be written to memory, even after completion of a given measurement without loss of data, until the maximum capacity of 30,000 measurement values is used. The data can be stored to intermediate memory. The system records measurement values in relative time. Depending upon the measured quantity, the interval can be set in steps of 10 ms, 100 ms, 1 s, 10 s and 60 s. Individual measurement values can also be saved to memory by pressing a key. Scope of Delivery - Multimeter with protective rubber holster, 1 pair of safety test leads (1.5 m) with 4 mm diameter, 1000 V CAT III, 600 V CAT IV (KS17-2)
- 2 batteries, 1.5 V, type AA
- CD with operating instructions
- 1 DKD calibration certificate
- HC20 Hardcase
Overload Protection The instrument is safeguarded against overloading in all measuring functions. All current measuring ranges are equipped with a self-resetting, electronic fuse. Averaging Filter for Noisy Measurement A digital filter (1/2/4/8/16 measurement values) is used to smooth noisy measurement signals. Battery Charging Status - Power Saving Circuit Battery operation allows for mobile use of the instrument for demanding maintenance work and calibration tasks. An optional mains power pack can be utilized for stationary, long-term operation. If user selected, the device is switched off automatically if the measured value remains unchanged for a period of between 10 and 59 minutes (adjustable), and if none of the controls are activated during this time. DKD Calibration Certificate The multimeters are furnished with an internationally accepted DKD calibration certificate (recognized by EA and ILAC). After the specified calibration interval has elapsed (recommended interval: 1 to 3 years), the multimeters can be inexpensively recalibrated by any calibration laboratory. |
