5. Using the NUMBER buttons, enter the desired value
(ATM style, lagging zeros are required).
6. After the value is entered, aim the controller at the sensor and
press the ENTER button.
• The Ultima X Series Monitor shows the new span gas value.
• If the span gas concentration value is higher than the full scale
range, the Ultima X Series Gas Monitor displays the current
span value setpoint.
• The Ultima X Series Gas Monitor span gas value is now
changed to the selected concentration.
Procedure 3.
Setting the Range on an Ultima X Series Sensor
1. Press the SEND button.
• The display prompts: SEND?
2. Press the SPAN button.
• The display prompts: Span Option +
3. Press the + or - button until the display prompts: UltimaX Range.
4. Press the ENTER button.
• The display prompts: Range ####.##
5. Using the NUMBER buttons, enter the desired value
(ATM style, lagging zeros are required).
6. After the value is entered, aim the controller at the sensor and
press the ENTER button.
• The Ultima X Series Gas Monitor shows the new
full scale gas value.
• The SPAN (CAL) value must be within the range of the
instrument. Therefore, if the combustible sensor is calibrated
at 55% LEL, the instrument range cannot be changed to
50% LEL until the SPAN value is decreased.
• An alarm setpoint cannot be set outside the range of the
instrument. Therefore, the alarms must be decreased if they
were previously changed from the original settings of
10%, 20%, and 30% LEL.
• If the above two statements are true, the range can be
decreased to the desired full-scale limit.
• The Ultima X Series Gas Monitor range value is now changed
to the selected limit.
