1. Set SW 1 down for 10 VDC excitation or up for 5
VDC excitation. By default the IAA amplifier is set to
10 VDC at FUTEK.
2. Set the gain DIP switch (SW3) to the appropriate gain
level. By default the gain is set with switch 4 up for
a 2 mV/V sensor. (
Use our online gain setting Excel
sheets on the
FUTEK support webpage
to find the
appropriate gain DIP switch setting for your sensor’s
mV/V output.)
3. With the sensor and IAA amplifier completely con-
nected apply the 12.5 to 26 VDC.
4. With no load on the sensor adjust the Zero poten-
tiometer until the output is as close to 0 VDC as
possible.
5. With a known load placed on the sensor adjust the
Span potentiometer to as close to the appropriate
output level as possible. For example, 10 VDC for a
full load output.
6. Remove the load and reconfirm the zero load output,
and then reapply the known load and re-confirm the
span output.
Setup Steps
IMPORTANT NOTE:
Do not connect the device to the power supply when the power supply is already on.
Note:
Adjusting the Span will affect any system calibrations.
Adjusting the zero will not.
FUTEK’s online calibration tool allows you to
