• Checking
Manual Checking of Zero and Span is conducted by entering CHK Z & S routine.
This routine operates the Solenoid Valve Drives 1 and 2. Therefore, if the 2500 is
configured and plumbed for AUTOCALIBRATION or AUTOCHECKING, the Zero
Calibration Sample and Span Calibration Sample connected for automatic routines will
also be used in the Manual Check Zero and Span routine.
If AUTOCALIBRATION or AUTOCHECKING routines are not being used, the user may
still wish to utilise the Solenoid Valve Drives 1 and 2 to switch solenoid valves
controlling the samples for greater convenience.

4.4 Auto calibration and autocheck setup
Either AUTOCALIBRATION or AUTOCHECK can be configured on the 2500 - these
are described as ‘Auto calibration’. In either case, suitable Zero only, or Zero and Span
Calibration Samples must be permanently plumbed via solenoid valves into the
sampling system from which the 2500 is fed.
The Auto calibration is configured to the user's requirements in the Set Up Cal Parm
function.
Suitable solenoid valves are plumbed and wired to the 2500 as described in the
installation manual.
The required Auto calibration can be initiated by any of 4 methods:
i) From the display panel, by the user entering the ONE CYCLE function. This
performs one complete Auto calibration operation only. This is also useful for
testing the configuration as set up.
ii) From the 2500's real-time clock. The Auto calibration PERIOD (time between
each Auto calibration initiation) is adjustable from 1 hour to 59 days and 24
hours. A setting of 00 days, 00 hrs. will prevent timed initiation. The start time for
the first cycle is also adjustable.
