5. CJC Output

The built -in CJC Circuitry produces a 10mV per Deg C output with

0.0 Volts @ -273 Deg C. The

OME-A-822 should be protected from

drafts and direct sunlight in order to accurately reflect room
temperature.

CJC Calibration:

1. Connect the OME-A-82X series to the OME-DB-8225 CN1

2.Set OME-A-822HG/DG to Single-Ended Mode

3.set JP1 to 1-2and JP2to 2-3 ( Single-Ended mode)

4.Read the temperature from a Digital thermometer placed near

D1/D2 (See OME-DB-8225 Layout).

5.Read OME-A-82X AI0 (Single-Ended Channel 0)

6.Adjust VR1 until a stable reading of 10mV per deg C is attained.

For example, when the environment temperature is 24 deg C. the

reading value of CJC will be 2.97V

(273 deg c +24 deg c ) X 10 mV/deg c = 2.97V

You will need an A/D channel for CJC calibration. AI0 is reserved for
CJC calibration in single ended mode and CH0-HI & CH0-LO is
reserved for differential mode.

6. Open Detect and Input Filtering

Open thermocouple detection and input filtering are provided on the
OME-DB-8225 by installing 3 resistors and a capacitor on the desired
input channel. For example, if channel 0 is the desired channel,
RA0and RA8 must be removed and RD1 must be installed. These
biasing resistors will slowly pull an open input channel to 0 Vdc. This 0
Vdc condition can be sensed and flagged in software.

7. Voltage Divider & Current input

7.1. Voltage Divider

If the input voltage signal is greater than the input range of the
OME-A-82X, a voltage divider can be used. The OME-DB-8225
provides 2 resistor locations on each input channel that can be used
to reduce the input voltage signal.
Follow the steps shown below

Step 1. Change RA0 (0 Ω) resistor to 10KΩ (0.1%)
Step 2. Install 10 KΩ (0.1%) on RB0 (Voltage Signal / 2)

V/n : n = RB0 / (RA0+RB0)

7.2. Current input

If you want to measure current input signal, you should change
resistor RA0 (0Ω) to 250Ω . Follow the steps show below

Current Signal range: 0 to 20mA
RA0 change to 250Ω
Voltage =20 ma X 250Ω = 5V ; Range 0 to 5V

Formula:

input voltage signal = input current signal x 250Ω
