Three Function Operation
The Ultima Calibrator is equipped with three buttons for the following
functions:
1. ZERO Button:
• Performs a zero function on the Ultima/Ultima X Series Gas
Monitor; periodically, the monitor may require only a zero
adjustment.
2. CALIBRATE Button:
• Performs a zero and span calibration function on the
Ultima/Ultima X Series Monitor; During a complete calibration,
the Ultima Gas Monitor requires both a zero and span
check gas.
3. ADDRESS Button:
• Displays or changes the multiplex address on the
Ultima/Ultima X Series Monitor, if so equipped.
To Operate:
• All Ultima Calibrator operations are performed by simply pointing
the Calibrator at the Ultima/Ultima X Series Gas Monitor display
from a distance of no greater than six inches (FIGURE 1-2).
Communication to the Ultima/Ultima X Series Gas Monitor is made via
a one way, digitally encoded IR link to ensure tamper-proof and reliable
nonintrusive communication.
