1 minute (displaying zero), the manometer is automatically set on stand- When the low battery indicator light, the battery of the manometer will have to be recharged. To do this, connect the DPC 20 to the 220 V adapter and let it charge for 8 hours. -
Page 6: Configuration Of Parameters
MANOMETER DPC 20 2. CONFIGURATION OF PARAMETERS The configuration of the parameters is performed using the two keys The manometer DPC 20 provides the possibility of configuring the following five parameters: 1. Unit of measure 2. Display 3. Limits of tolerance 4. -
Page 7: Displayed Value
MANOMETER DPC 20 2.2 Displayed value Three different displays are available: Parameter N° 2: Displayed value [0 - 2] 0 = instantaneous value 1 = minimum 2 = maximum The option 0, instantaneous value, enables displaying the pressure just like an ordinary manometer. - Page 8 The manometer will then display 00. 2.5 Calibration IMPORTANT! The manometer DPC 20 is calibrated at delivery. Therefore the manometer needs no calibration before you use it. The calibration parameter is activated only when a subsequent calibration of the device is to be made.

MANOMETER DPC 20 pressure the manometer displays (P P P) to indicate that it is taking this value into account. Then release the -key to go back to measurement mode. The calibration is over! 2.6 Measurement of differential pressure Two different ways of measurement are available. The direct pressure mode shows the measured pressure. -
Page 10: How To Measure
3.1 Measuring without recording of values If sample size is set to zero, no measurements are recorded in the DPC 20. This implies using the DPC 20 as an ordinary manometer without recording measurements. When setting sample size to zero, pressing after a measurement resets the memory and displays a zero. -

It enables analyses of data to prevent manufacture of bad parts. To use the manometer DPC 20 with the SPC400 Aerosol, they will have to be connected by the appropriate cable (reference 45310). The setup defined in the SPC400 Aerosol must include a pressure characteristic (see SPC400 Aerosol User’s... -

Important : Once all pressure measurements have been downloaded to the SPC400 Aerosol, leave the manometer connected until the message « end of sample » appears on the screen. This is to allow memory reset of the DPC 20. 5. HOW TO USE THE SERIAL LINK (RS-232) This interface enables release and transfer of measurements to a PC or an SPC400 Aerosol as well as loading of configuration parameters from a PC. -

MANOMETER DPC 20 5.2.6 Imposed stand-by Command: ICrLf When receiving this command, the manometer is set on stand-by (imposed stand- by): ICrLf no response (on stand-by) 6. MAINTENANCE OF THE MANOMETER The adapters for different valves are very easily screwed off, to enable access to the flush mounted membrane of the pressure gauge. - Page 16 Version 1.4 DPC_MA14.doc...
