- Range - Digit 3 - Digit 0 This packet indicates the full scale range of the meter. Digit 3 i the most significant digit on the LCD panel, and When the meter operates in continuity mode, diode mode digit 0 is the least significant digit. When the LCD panel or current (A) mode, this packet is always 0110000 since shows OL, the serial port outputs 4000.
- Option 1 General Specifications This packet contains information on special measurement Display: The Liquid Crystal Display (LCD) modes. The format of this packet is shown below. The with a maximum reading of 4000 and three non-constant fields is set to one when the meter 82 segments bar graph.
