MSA Ultima X Series Instruction Manual

Ultima Calibrator
The Ultima Calibrator allows the following
functions:
• Zero
• Calibration (zero and span)
• Changing address for some models.
Ultima Controller
The Ultima Controller also provides the above
functions plus access to the following features:
• Three levels of alarm and relays
• Date of last successful calibration
• Maximum gas readings over selected time
periods
• Average gas readings over selected time
periods
• Changing span gas value from factory-set value
• Access to real-time clock for time and date
• Changing of full scale value.
NOTE: See Ultima/Ultima X Controller/Calibrator manual
(P/N 813379) for full functionality.
Note on Resetting Latched Alarms with Controller or Calibrator
When an Ultima X Series Gas Monitor has an active latched
alarm (indicated by a flashing alarm display):
• An infrared (IR) remote device (such as the Ultima Calibrator or
Controller) may be used to reset this alarm.
• The next IR command it receives from a calibration device will
reset the latched alarm (if it is not beyond the alarm threshold).
The intended IR command will be ignored and interpreted as an
’alarm reset.’ When the latching alarm function is inactive, other
valid IR commands may be used.
Ultima X Series Gas Monitor Calibration Output Signal
The Ultima X Series Gas Monitor is shipped with the calibration
output signal disabled so the output signal will track the gas
concentration value during the calibration process. In some
applications, it may be desirable to disable or lock the output to a
pre-determined output value to prevent activation of alarm devices.
The calibration signal can be enabled using the Ultima Controller.
When the calibration signal is enabled, the output signal is 3.75
milliamps for the 4 to 20 milliamp output models.
