Allow the to stabilize at atmospheric pressure and ambient
temperature for 10 to 15 minutes before running AutoZ.
Note
If AutoZ is on, the AutoZ value will be applied while running the
calibration of molbox RPTs and an AutoZ indication is included
in the run calibration screen (See Section 5.2.4.1).
OPERATION
To access the AutoZ function press
[TARE]
,
<4AutoZ>
. The display is:
1.

offset
for the two RPTs.
Note
P

should be zero when the is new or has just
been calibrated.
•

Note
The value of P

Edit AutoZ
Caution

entering inappropriate values and turning ON AutoZ may result
in out of tolerance measurements. In normal operation, the
value of the AutoZ offset, P
offset
, should be changed using the
run AutoZ function (see Section 3.4.4.4.2). Before editing P
