Input impedance adjustment
The I-8014W provides three input impedances such as 20k, 200k (default setting)
and 20M Ohm to meet system requirement. For most of cases, 200k is good enough.
Every time when the input impedance is changed on a calibrated module, it is
necessary to calibrate the module again, refer to Calibration, page17, if you are using
I-8000 or iPAC-8000 (MiniOS7 platform controller); if you use WinCE or WES
platform unit, refer to page 28 for the calibration process.

This section gives the getting started guide and calibration process for using I-8014W
on MiniOS7 and Windows platforms individually.
This section contains getting started guide and calibration process for using I-8014W:

Calibration, page 17
Getting Started Guide
The executable file AI_INFO.EXE in basic_info folder of I-8014W demo could be used
to get the basic information of the I-8014W and verify the AI read function. The basic
information includes:
●Version number and published date of library.
●FPGA version
●The Single-ended/ differential jumper setting position
●The gain and offset values for every input range
●The data read on each channel
(See Demo Programs Location, page 12 , to get AI_INFO.EXE in I-8014W demo
program)

Step 1. Refer to Jumper setting, page 8, make sure the Differential / Single Ended
select jumper is in differential position.
Step 2. Connect your stable signal source (ex. a battery output) to I-8014W by
differential wiring as below.
Step 3. Connect the power supply to the unit, and connect the control unit and PC by
RS232 cable.

Step 4. Launch AI_INFO.EXE on PC, verify the basic information and AI read from
each channel as follows:
Tips & Warnings
Unused channel should be connected to GND to avoid floating.
Library and FPGA version information
Single-ended/ differential jumper position
Verify the AI data from each channel.
Gain value is around 33000, when it is far
from 33000 means that the value is
incorrect.

Calibration
Every one of I-8014W is factory calibrated and well verified. Usually, it is unnecessary
to calibrate the module, unless the input impedance is changed on a calibrated
module, or the accuracy is lost.
To calibrate the I-8014W, in addition to plugging the I-8014W in the slot of controller,
the following items are needed:
●One stable calibration source such as 3 1/2 digit power supplier (or better) or a
battery output.
●One 4 1/2 digit voltage meter (15-bit resolution or better)
●Calibration Program: see page 12 to get the demo program located in I-8014W
demo program.
Tips & Warnings
1. An unstable calibration source will cause the calibration fault and
affect the data acquisition accuracy.
2. If you would like to calibrate ± 20 mA, select ± 2.5V instead, the
two types use the same gain and offset values.
3. The calibration program use channel 0 to accept calibration
source only.
