Rosemount Analytical Inc. A Division of Emerson Process Management Setup and Operation 3-13
World Class 3000
Rosemount Part Number
3530B07G02 for probe 8%
oxygen in nitrogen in dispos-
able bottle.
3 A check valve is required at
the probe (between the cali-
bration fitting and the gas line)
to prevent the migration of
process gases down the cali-
bration gas line.
(b) Calibration with a Portable Rose-
mount Oxygen Test Gases Kit.
1 A typical portable test calibra-
tion setup is shown in Figure
3-4. For Manual (semiauto-
matic) calibration, remove cap
plug from the calibrate-in-
place fitting. The cap plug
must be retained to seal this
fitting after calibration is com-
plete; failure to do so may
render the probe useless if
the system pressure is slightly
negative. The reference gas
should be flowing as in normal
operation.

d. Manual (Semiautomatic) Calibration
Procedure
Consult Safety Data Sheet 1M03296
before performing any work on the
CENELEC approved IFT 3000.
The following procedure relates to an op-
erator initiated calibration selected at the
IFT by pressing the CAL key. The calibra-
tion is manually performed by the operator
upon data queues from the IFT. Any system
without an MPS 3000 Multiprobe Test Gas
Sequencer must follow these steps.
1. Press SETUP to display the SETUP
menu. Select PROBE CALIBRATION
sub-menu. Ensure that Auto Cal is dis-
abled. Set the cursor on Auto Cal.
Press ENTER. Set Auto Cal to NO if
not already done.
2. Press the CAL key. Select PERFORM
CALIBRATION sub-menu. "Press EN-
TER to start Manual Calibration" will
appear on the LCD display. Press EN-
TER to start. Follow the data queues.
