6. Turn on the processor, I/O chassis, and the industrial terminal.
7. Place the processor in the TEST or PROG mode.
8. Output full scale (+20mA) either with write block transfer data or
by placing the LAST STATE configuration jumpers in the MAX
position.
9. Adjust R66 until the reading is +5V (20mA) +2mV (Figure 6.6).
10.Output +4mA (1V - minimum scale) either with write block
transfer data or by placing the LAST STATE configuration
jumpers in the MIN position.
11. Adjust R67 until the reading is 3/4 the difference between 1V and
the initial minimum scale reading.
