To complete the
POA
calibration, compare the pressure reading on the display (
P
) with the pressure reading
on the pressure reference meter. (See the following Step for a full explanation of the calibration screen.)
Adjust the pressure reading using the up or down arrows on the POA offset field.
NOTE: The difference in two readings should be within 0.5Kpa. If the two readings cannot be matched
precisely, set pressure reading on unit to one count below the reading on the pressure reference
meter.
13. Explanation of the calibration screen:
14. After completing the POA calibration, use the arrows below the POS and TO values to set them to 00 ,
if the displayed values are not already 00.
NOTE: Offset adjustment arrows DON’T have to be highlighted to change values.
STAGE 4. Adjusting the pressure at vacuum
15. The cycle then continues to the vacuum phase. The POV field on the display will be highlighted.
16. Wait for the vacuum to reach 60 Kpa or less . Once the vacuum is in this range, compare the reading
on unit’s display ( P ) with the reading on pressure reference meter. The pressure reading can now be
adjusted by using the up or down arrows on the POV field .
A red rectangle highlights the offset to
be adjusted at each stage of the
calibration.
