Commissioning and Set-up Examples
How to change the engineering units.
Objective:- Change the engineering units from the default, pascals, to Bar.
From Monitor mode:-
Press [CHANGE] the transmitter will display
{VIEW}
Press [CHANGE] {ACCESS 1}
Press [SELECT] {INPUT}
Press [SELECT] {PV UNITS}
Press [SELECT] {Pascal}
Press [CHANGE] The display will flash the next available unit, press change until, Bar is
displayed, press and hold select for two seconds to save the new units. All engineering units will
be displayed with the new selection.
How to set the range of a 0 to 10 Bar instrument.
Objective:- Re-range the transmitter 0 to 3 Bar, without reference to a pressure source
From Monitor mode:-
Press [CHANGE] the transmitter will display
{VIEW}
Press [CHANGE] {ACCESS 1}
Press [SELECT] {INPUT}
Press [SELECT] {PV UNITS}
Press [CHANGE] {RANGEHI}
Press [SELECT] {10.000 BAR}
Press [CHANGE] The display will clear, the first character will flash.
The new URV can now be set to three bar, the value is entered in the selected engineering units.
Use the change and select keys to enter the value, select the sign first, ( + ), then repeatedly
press change until the desired character is displayed, ( 3 ), select it, repeatedly press change until
the decimal point character is shown, ( o ), select it, repeatedly press select until the last character
is flashing, when select is pressed the whole display will flash, press and hold select for two
seconds to save the new value.
The URV of the transmitter is now set to 3.0 Bar, the instrument will output 20 mA for an input
pressure of 3.0 Bar.
If the instrument is re-ranged with reference to a pressure source, the digital display may need to
be trimmed using TRIM URV, TRIM LRV to match a site pressure standard. This can improve the
accuracy at large turndowns; the accuracy of the pressure source used for reference must be
considered.
