 Procedure (Figure 3-10)
This sub-menu divides into two selections, a one-point
calibration and a two-point calibration.
C
AUTION:THIS INSTRUMENT CONTAINS STATIC SENSITIVE COMPONENTS
HANDLE WITH EXTREME CARE.
The calibration procedure is protected by a PIN
and the CAL option link LK1 located on the PCB.
To carry out a calibration LK1 must be in the

position.
With the instrument connected to
an appropriate pressure standard,
the calibration sub-menu accessed
through the set-up menu.
One-point calibration
For the one-point calibration the instrument stores the
relationship between pressure and output.
Important note
The calibration carried out at manufacture is a two-point calibration
against a pressure standard traceable to National Standards. Carrying
out a one-point calibration can significantly down-grade the
instrument's accuracy if in doubt consult the manufacturer before
proceeding.
Two-point calibration
This calibration provides a more accurate reading of the
applied pressure, the instrument calculating a more complex
correction for the displayed reading.
