ES51985
6000 Count AUTO DMM
The meter always outputs the current input value to the serial port in spite of HOLD
mode. Each block is repeated twice in one conversion cycle. The detailed data format of
each packet is listed above.
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-FC4 switch.

Note: 1*.The judge bit in the Status packet determines whether the unit is Celcius or
Fahrenheit.
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.
