4.1.1.1 User Setup A: Display Range Select
This parameter allows the user to map the display and electrical output range scale of the model
1100 to suit the application (Appendix E – Range / Output Chart).
Valid Settings: 1 (fixed range 0-1 %) • 2 (fixed range 0-10 %) • 3 (fixed range 0-25 %) • 4 (fixed
range 0-50 %) • 5 (fixed range 0-100 %) • 8 (low auto-range) • 9 (high auto-range) • 10 (full auto-
range) See Appendix E
4.1.1.2 User Setup 1: Alarm-1 Relays Ascending/Descending Action
This parameter allows the user to set the Alarm-1 relay action to ascending (the relay is set to its
active state when the oxygen level is above the Alarm-1 level set point) or to descending (the relay
is set to its active state when the oxygen level is below the Alarm-1 level set point).
Valid Settings: 0 (Ascending) • 1 (Descending)
4.1.1.3 User Setup 2: Alarm-2 Relays Ascending/Descending Action
This parameter allows the user to set the Alarm-2 relay action to ascending (the relay is set to its
active state when the oxygen level is above the Alarm-2 level set point) or to descending (the relay
is set to its active state when the oxygen level is below the Alarm-2 level set point).
Valid Settings: 0 (Ascending) • 1 (Descending)
4.1.1.4 User Setup 3: Analog Voltage Output Setting
This parameter allows the user to set the Analog Output Voltage full scale to 1, 5, or 10 volts. Note
that the software settings must match the RA and RB jumper settings on the Main CPU PCB
(section 4.1.3).
Valid Settings: 0 (0-5 VDC) • 1 (0-10 VDC), 2 (0-1 VDC)
NOTE: Maximum voltage output for setting 0, is 4.93 volts.
4.1.1.5 User Setup 4: Serial Output Format
This parameter allows the user to set the RS-232 communications timed output format.
Valid Settings: 0 (Output on Request) • 1 (Human Readable) • 2 (Machine Code) • 3 (Machine
Code with Checksum) • 4 (Tab Delimited)
4.1.1.6 User Setup 5: Analog 4-20mA Output Calibration
User Setup mode 5 allows the user to adjust the high and low span values of the Analog 4-20mA
output from the model 1100. To access user setup mode 5, use the “MODE” key to scroll through
the user setup mode menu as normal, until user setup mode 5 is reached. The LED display will
show “4.00” to indicate that the unit is ready for the low span output adjustment.
Adjust the low span output: Connect a multi-meter to TB3, Pin 7 (+), and TB3, Pin 8 (-). Set the
multimeter to read milli-Amperes. Use the “UP” and “DOWN” keys to adjust the analyzer LED
display to match the reading on the multi-meter.
Adjust the high span output: Press and release the “MODE” key once. The analyzer LED display
will show “20.00” to indicate that the unit is ready for the high span output adjustment. With the
multi-meter still connected to TB3, Pin 7 (+), and TB3, Pin 8 (-), use the “UP” and “DOWN” keys to
adjust the analyzer display to match the reading on the multi-meter.
