Calibration/Aspirator Air
Required Calibration Gases and Tubing
See Specifications for information on calibration gases. The span gas
is the high gas; the zero gas the low gas.
The span gas must be 10 times greater than the zero gas. For example, if the
zero gas is 1 % O
2
, the span gas must be 10 % O
2
or higher.
• O

Span Gas
Instrument air (20.9%) or from 1.0–100 % O

.
• O

Zero Gas
From 0.1–10 % O

, balance N

For example, if using an operating range of 0 to 2000 ppm combustibles, use
1200 ppm CO, 1–2 % O
2
, balance N

.
Flow Calibration
A flow calibration must be performed upon analyzer startup. The WDG-V UOP
analyzer should be mounted on the process, fully up to normal operating tem-
perature, and have typical process gas flowing prior to performing the calibra-
tion.
• Once normal operation has been achieved, from the
Calibration
menu,
select
Flow Alarm Setup
.
• Press
Enter
to continue, then
Accept
to save the Flow Temperature mea-
surement.
The
Flow Alarm
setpoint is automatically set to 100 °C below the
Flow Temp
shown.
For process temperatures below 350 °C or for custom temperature
thresholds, contact the AMETEK Service Department.
