1) [BFM #0] Output mode select: The value of BFM #0 switches the analog output between voltage and
current on each channel. It takes the form of a 4 digit hexadecimal number. The first digit will be the
command for channel 1 (CH1), and the second digit for channel 2 (CH2) etc. The numeric values of
these four digits respectively represent the following items:
H
C H 4 C H 3 C H 2 C H 1
Switching the output mode resets the I/O characteristics to the factory-default characteristics. Refer to the
performance specifications described in section 4.
Example: H2110
