4.2 RANGE
This packet indicates the full scale range of the meter. When the meter operates in
continuity mode, diode mode, or current (A) mode, this packet is always 0110000 since
the full scale range in these modes are fixed. The following table lists the code for each
range in each measurement mode.

4.3 DIGIT 3 – DIGIT 0
Digit 3 is the most significant digit on the LCD panel, and digit 0 is the least significant
digit. When the LCD panel shows OL, the serial port outputs 4000.

Because the cycle time of measurement for continuity/diode mode is only 70ms, the
least significant digit may not be accurate.
4.4 STATUS
The format of this shown below. The Judge field is meaningful only when the Function
packet indicates Temperature mode. In Temperature mode, judge is 1 if the unit is ℃
and is 0 of the unit is ℉ . Sign field indicates whether the minus sign on the LCD
panel is on or off. BATT field is one of battery low condition is true. OL indicates input
overflow.
