The TUNE fuction allows the user to
precisely adjust the 4-20 mA output to
compensate for any errors in the output
circuitry. Normally, find turning the 4-
20mA output is not necessary.
The make the adjustment, place an
accurate current meter in series with the
4-20 mA output, with the appropriate loads
connected. When the TUNE menu is
selected, the controller puts 20 mA out 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

RUN MODE

With "N" selected, pressing the
key will NOT store the selection, but
simply return to the OUTPUTS Menu.
This function is useful if you wish to
view the current selection without
making any changes.

The example below shows the 4-20 mA set to 4mA =400uS and 20mA =
1800uS. The output would then span 4 to 20 mA for a conductivity swing of 400
to 1800. Note that the span can reversed, in that 4 mA can be set to a high
conductivity value, and 20 mA can be set to a low conductivity value, effectively
reversing the control direction.

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. See Section 3.12 for wiring diagram.
Channel 1 (the primary output) is located on the flip out door,
terminal plug P6. Channel 1 is dedicated to track the process
and has fully independent and fully adjustable 4 & 20 mA
output adjustments. This will enable the operator to span the
output over the desired range.
