Vaisala MGP260 Series, User Manual, Page: 52 / 92

The accuracy of field calibration and adjustment is dependent on a number of
factors such as sufficient stabilization time, calibration setup conditions, and
reference quality. To ensure fully accurate calibration and adjustment results, use
the traceable calibration and adjustment services provided by Vaisala.

8.2.1 Compensation mode during calibration
When you start to calibrate the probe with Insight, the probe enters calibration mode, and the
compensation mode is automatically switched to
Setpoint . In this compensation mode, you
must enter the conditions of your calibration environment as temporary setpoint values in the
Compensation setpoints tab of the calibration menu.
When you exit calibration mode, the values you have entered in the Compensation setpoints
tab remain in use as the current setpoint values, but the compensation mode switches back to
the selection that was in place before starting calibration (either
Off , Setpoint , Measured , or
External ).

8.2.2 Flow-through adapter
The MGP260 flow-through adapter (Vaisala order code: 258877) is used in sampling line
installations and field calibration and adjustment to achieve a controlled flow of gas to the
probe.
The flow-through adapter is delivered assembled with a mounting clamp, mounting plate, and
a gland for attaching the probe to the adapter. Figure 22 (page 51) shows the main parts of
the flow-through adapter and mounting kit.
