Configuration
The G408 has 18 input range settings. Trim
potentiometers allow 50% input zero and
span adjustability within each of the 18 full
scale input ranges.
Unless otherwise specified, the factory pre-
sets the Model G408-0001 and G408-1001
as follows:

Output Range:
4-20mA

-10 to +10V
The DC power input accepts any source
between 9 and 30V; typically a 12V or
24VDC source is used (see Accessories).
To minumize interference from electrical
and magnetic fields, the use of shielded,
twisted pair wires on the input and output
is recommended.
WARNING!
Do not change switch settings
with power applied. Severe damage will result!
Refer to Tables 1 through 4 for the proper
switch settings. Use the switches on SW1 to
select the input type (voltage or current) and
also to select the desired input range and
function setting. Use SW2 to select the de-
sired output type.

Calibration
1. After configuring the DIP switches, con-
nect the input to a calibrated DC source.
Connect the output to the actual device load
(or a load approximately equivalent to the
device load) and apply power.
Note: To maximize thermal stability, final
calibration should be performed in the oper-
ating installation, allowing approximately 1
to 2 hours for warm up and thermal equilib-
rium of the system.

2. Set the calibrator to the desired minimum
input and adjust the zero potentiometer for
the desired minimum output.
3. Set the calibrator to the desired maximum
input and adjust the span potentiometer for
the desired maximum output.
4. Repeat steps 2 and 3, as necessary, for best
accuracy.
