Teledyne 2230R instruction manual Voltage Analog Output Range, Power-On Self Diagnostic Error

MODEL 2230R, Process Hydrogen Analyzer

The user can change to another current range of the analog output in the field. Please refer to the “I” command in Section 4.3 SERIAL COMMUNICATION.

Below is the table for standard analog output voltage ranges:

Voltage Analog Output Range

0 V to 5 V

1 V to 5 V

0 V to 4 V

0.5 V to 4.5 V

Power-On Self Diagnostic	Error
0 V	5 V
0.5 V	0 V
5 V	4.5 V
0 V	5 V

The user can change to another voltage range of the analog output in the field. Please refer to the “V” command in Section 4.3 SERIAL COMMUNICATION.

WARNING: THE USER CANNOT CHANGE FROM A CURRENT RANGE TO A VOLTAGE RANGE OR FROM A VOLTAGE RANGE TO A CURRENT RANGE OUT IN THE FIELD. THIS REQUIRES A FACTORY MODIFICATION.

4.3SERIAL COMMUNICATION

The user can monitor output and interface with the unit to perform calibration or adjust user settings via the serial communication connector. The serial communication is accomplished via an RS232 (optional RS422) interface.

Serial	Any serial port two-way communications software such as terminal
