Analog Output Check-Output Simulate
This feature allows the user to simulate the electronics and the signal output. A know current is added to the
analyzer electronics internally to generate equivalent analog signal output. This feature allows the user to check all
interconnections from the analyzer to the signal output recording device before installation of sensor thus preventing
the user to open the sensor bag before the analyzer installation is complete and satisfactory. To simulate signal
output
Access the MAIN MENU by pressing the MENU key.
Advance the reverse shade cursor using the ARROW keys to highlight CALIBRATION and then select OUTPUT
SIMULATE.
Press the ENTER key to select the highlighted menu option.

PRESS UP OR DOWN TO ADJUST
OUTPUT ENTER/MENU TO RETURN
Pressing UP or DOWN key will increase or decrease the output by 5% of the full scale signal each time. Check the
output on the external recording device or voltmeter/ammeter. The output on the external recording would be the %
of the full scale signal selected, for example, 0% will represent 4.00 mA, 25% value will represent 8 mA and 50%
span value will represent 12.0 mA of the 4-20 mA full scale. After SIMULATION is complete, press ENTER/MENU key
to return to SAMPLE mode.
Note: To perform "Calibrate-Output Simulation", an external recording device must be connected between the
negative terminal of the power source and negative terminal of the transmitter.
