E-MAIL:tosstar@163.com QQ:152623914 The Model 856 is an auto-ranging 4.5 digit digital multimeter. This portable DMM has all of the conventional voltage current resistance continuity and diode measurement functions. Some of the additional standard features are comparison of measured results frequency measurement and bargraph display and calculated functions for deviation relative and decibel measurements. AC voltage and current measurements are made via a true rms measurement technique. The 3-level comparator allows measured results to be displayed as high go or low with respect to preset upper and lower limits. AC voltage readings can be displayed in dBm or dB relative to an arbitrary level. The large green LED display is easy to read and gentle on the eyes. |
