5.2.3 SET-UP AND PREPARATION
To set-up and prepare the PPCK+ for calibration of an RPT:
n
Set the PPCK+ on a stable surface near the calibration standard at a height as close as
possible to the calibration standard's reference height. Consider the connections that
may need to be made to the rear panel and access to the front panel display and keypad.
o
Connect the output of the calibration standard to the PPCK+ TEST1 port (DH200 F).
(See Section 2.3.4.)
DH200 F is a gland and collar type fitting for coned and left hand threaded 1/4 in. (6
mm) OD tube, equivalent to AE SF250C, HIP LF4, etc. IT MAY DAMAGE THE FITTING
AND MAY BE DANGEROUS TO THE OPERATOR TO USE INCORRECT FITTINGS.
p
Shut the PPCK+ VENT if it is open (see Section 3.1.2.2). Abort pressure control.
The PPCK+ is calibrated with pressure control idle. This allows its RPT to be calibrated
as a measuring device. Pressures are normally generated and adjusted by the pressure
standard, not by the PPCK+.
q
Allow PPCK+ to warm up with power on for at least 30 minutes before running
the calibration.
NEVER apply pressure to the PPCK+ TEST port that is greater than 105 % of PPCK+
range 3. Damage to internal PPCK+ RPT could result.
5.2.4 RPT CALIBRATION USING CALTOOL FOR RPTs SOFTWARE
To calibrate PPCK+ using CalTool software (supplied on the General Accessories Disk),
refer to Sections 5.2.1, 5.2.2 and 5.2.3 in this manual and then refer to the CalTool for RPTs
Software Manual (supplied on the General Accessories Disk).
5.2.5 EDITING AND VIEWING RPT CALIBRATION INFORMATION

PURPOSE
RPT calibration information is available for each RPT range. Fields include:
•
The calibration date
•
The value of ZNATERR (see Section 5.2.6)
•
The value of PA (see Section 5.2.1.1)
•
The value of PM (see Section 5.2.1.1)
These fields can be viewed and/or edited. Viewing and editing calibration information is
range specific.
