The HT8051 is a professional portable digital process calibrator for generating and measuring direct voltage up to 10 V DC and DC current up to 24 mA. In generator mode, you can manually switch between 0-20mA or 4-20mA and select the percentage values, depending on the set current (0% = 4 mA, 100% = 20 mA), as well as various ramps output signals. There is a choice of a slow linear ramp, a fast linear ramp or a level ramp. An innovative knob allows top-easy Settings of the output signal with a resolution of only 0.001 mA or 0.001 V. The HT8051 also allows the measurement of current which is produced by external converter or a current converter to simulate. Each function can be comfortably directly by the function buttons and the rotary knob can be selected. The HT8051 is the ideal solution for the most common industrial applications and the use in laboratory area.This text is machine translated.
