A Micro-Processor based transmitter with digital double-display for pressure The display is powered from the 4…20 mA current loop.

MAX/MIN: Activating the right key brings the Max.- and Min.-values to the lower display
RESET: The Max.- and Min.-values are set to actual
ZERO SET: Set to the applied pressure
ZERO RES: Restores to factory settings
UNITS: The pressure values can be displayed in the following units: bar, mbar/ hPa, kPa, MPa, PSI, kp/cm2

PROGRAMMING THE ANALOG OUTPUT

OUTPUT: used to configure the analog output within the compensated range
ZERO: Executing ZERO when pressure is applied sets the analog output to 4 mA
FS: Executing FS when pressure is applied sets the analog output to 20 mA
b>FACT SETT: Analog output is set back to factory settings

PROGRAMMING BY PC:

The communication with the BUS-capable instrument is used with the KELLER PROG30/ READ30 software and the K106 converter via the RS 485 interface, allowing to read out the pressure values and the instrument characteristics. The analog output can be programmed without applying pressure to the instrument
