MENU-DRIVEN FUNCTIONS
Selection of the various functions is made easy using only a few keys through menu-driven choices. The LCD display shows the
options, with ‘Next’ and ‘Last’ keys giving access through the menu in both directions. The Up and Down keys allow the choices to
be explored without changing the selection until ‘Enter’ is pressed. ‘Escape’ returns the instrument to its normal function. With the
menu-driven system, modifications can be made to the programme without having to change any hardware.

CALIBRATION PRESSURE
Calibration pressure units are chosen from the menu. the options available are: Pa, kPa, µbar, mbar, bar, mmH2O, thouH2O, inH2O,
mmHg, inHg, PSI and PSF.

PPC500

The pressure is displayed as the upper figure in the LCD display with the selected units shown. A Full Scale reading of up to 24000
units is provided to give easy calibration of 2, 20, 200 scales, whilst retaining full instrument accuracy. The instrument is dual range
to give maximum range capability.

DATALOGGER
The optional built-in datalogger allows storage of calibration results to the PPC500’s memory. The PPC500 can be configured to
memorise the results from 20 instruments with 10 points, 10 instruments with 20 points, 40 instruments with 5 points or 60
instruments with 3 points. Tag No or serial numbers can be entered to provide unique information about the instrument being
calibrated. Results can be downloaded from memory through the RS232C to a PC for processing.
The PPC500 incorporates a high accuracy 5 digit meter with 20 volt and 20 mA ranges to read the output signal from the instrument
being calibrated. the PPC500 can also be programmed to display the signal in engineering units for the direct comparison with the
applied pressure. The third option displays percentage error. This makes calibration checks and corrections even easier and gives the
figures for direct entry onto a calibration chart.
