The amplifier functionality can be tested on its own
by confirming the following:
1. An open or the sensor disconnected from the
sensor side will will cause the amplifier to saturate
to full output or higher. Amplifier should be
powered with 12.5 VDC to 26 VDC through Pin 1
(+Vin) and Pin 2 (GND)
2. Connection of Pin 2 (+ Signal) and Pin 3 (– Signal)
on the sensor side will cause the amplifier to go
close to zero output condition.
Amplifiers with an offset induced using the amplifi-
er dipswitches would see the zero output condition
being the offset value. For example 5 V for IAA100
and 12 mA for the IAA200
All connections to amplifier should be made with the power first off.
Connection to power with power on can damage amplifier.
