The Controller has 2 4-20mA outputs, electrically isolated from
each other and ground. Either output can source current into a
maximum of 800 ohms.
Channel 2 has fully independent and fully adjustable 4 & 20
mA output adjustments. This will enable the operator to span
the output over the desired range.

The TUNE function allows the user to
precisely adjust the 4-20mA output to
compensate for any errors in the
output circuitry. Normally, fine tuning
the 4-20mA output is not necessary.
The make the adjustment, place an
accurate current meter in series with
the 4-20mA output, with the
appropriate loads connected. When
the TUNE menu is selected, the
controller puts 20mA out to the
terminals. Use the or
keys to adjust the 20mA output to get
exactly 20.
The TUNE value can be adjusted
over the range from 0 to 1000, these
are unitless numbers used for tuning
purposes only.
