6,600 Counts Auto DMM
mode. Each block is repeated twice in one conversion cycle. The detailed data format of
each packet is listed below.
4.1 FUNCTUON
This packet indicates the measurement mode of the meter. The following table
summarizes the transmitted code for each mode. Note that the encoding of this packet is
different from the encoding of FC1-FC5 switch.

1When the function code = 0110010, the measurement mode is determined by judge bit of Status packet.
If judge bit is 1, it means duty cycle mode. If judge bit is 0, it means ADP mode.
2When the function code = 0110100, the judge bit in the Status packet determines whether the unit is
Celsius or Fahrenheit.
3When the function code = 0111101 or 0111111, the measurement mode is determined by VBAR bit and
VASEL bit of OPTION1 packet.
4.2 RANGE
This packet indicates the full-scale range of the meter. When the meter operates in
continuity mode or diode mode, this packet is always 0110000 since the full-scale
ranges in these modes are fixed. The following table lists the code for each range in
each measurement mode.
