Calibration Procedures

Place the instrument receiving the signal from the Ultima X Gas Monitor
into CALIBRATION mode, if applicable.
It is necessary to put the receiving instrument in CALIBRA-
TION mode. If the instrument is not in CALIBRATION mode,
any alarm relays may energize and activate any safety
devices which are connected to the alarm relays of the
instrument.

Equipment Needed:

• Calibration Kit #40
• Appropriate ZERO and SPAN Gas Cylinders
(refer to the Ultima X Instruction Manual (P/N 10036101).
• An Ultima X Controller (P/N 809086) or an Ultima X Calibrator
(P/N 809997).
NOTE: If unsure of which SPAN gas to use or of the
SPAN gas value, consult your safety engineer or officer or
facility manager.
1. Locate the ZERO gas cylinder and the appropriate regulator and
tubing. Screw the regulator into the cylinder and connect the tubing
to the regulator outlet. Ensure that tubing is compatible with the
gas within the cylinder.
2. Before initiating the calibration procedures on the Ultima X Gas
Monitor, connect the tubing from the ZERO gas cylinder to the
Calibration Inlet (See FIGURE 1-1).
Zeroing the System
with the Ultima X Sampling Module
3. Initiate the calibration procedure on the Ultima X Gas Monitor;
refer to the Ultima X Gas Monitor instruction manual.
4. When the Ultima X Gas Monitor displays "APPLY ZERO GAS",
press and hold the button by the calibration inlet. Turn the knob
on the regulator to permit the ZERO gas to flow. The Ultima X
Gas Monitor will make all corrections to the zero signal; there are
no adjustments necessary.
5. When the Ultima X Gas Monitor is done zeroing, close the cylinder
valve, release the button by the calibration inlet, and quickly rotate
