2-9

These calibration kits contain zero caps to use in place of

zero calibration gas. These caps can only be used when the

ambient air does not contain the gas the monitor is detect-

ing. If there is any doubt, use zero gas when zeroing the

Ultima X Monitor; otherwise, improper calibration could

occur.

Span Gas Values

The Ultima X Series Gas Monitor is factory-shipped with a preset span

gas value (TABLE 2-2). This span gas value can be changed via the

Ultima Controller or a HART controller; otherwise, the span gas must

correspond to preset concentrations. See Section 3 of the

Controller/Calibrator Manual (P/N 813379) to change the span gas

value. See Appendix D for the equivalent HART command

The span gas value of Ultima X Gas Monitor catalytic combustible

models are pre-set to one of the broad categories shown in TABLE 2-2.

Specific span gas values for all combustible models are listed under

each category given in TABLE 2-3.

Always calibrate for the least sensitive gas or vapor (higher

number category) expected to be measured (TABLE 2-3);

otherwise, instrument readings may be incorrect.
