Methods
Only a single tap on the screen is required to open any item in
black or open any folder.
Terminology PV = Digital Value of Primary Variable (i.e. this is the parameter that
the transmitter measures - pressure, current, voltage).
PV AO = Digital Value of Primary Variable mA current.
DPI 620-IS CH1 = Analogue Value of Primary Variable (actual
calibrated value).
DPI 620-IS CH2 = Analogue value of Primary Variable mA current
(actual calibrated value).
DPI620 P1, P2 and IDOS reflect the analogue pressure values
measured by the relevant pressure ports on the DPI620-IS.
Range Values PV LRV = Lower range value of Primary Variable.
PV URV = Upper range value of Primary Variable.
Example: Transmitter under test has a range of -200°C to +800°C.
Setting the LRV to -20°C (zero value) and URV to +20°C (span value)
allows re-ranging the transmitter (zero & span) to specified limits.
The PV % of range in this example for a PV = 0°C is equal to 50%.
Minimise button.
• Switch between screens by selecting minimise
button.
• This allows switching between Windows to
review and adjust the PV during calibrations.
