4.5.2 Function 2: Display PV range, switch PV unit, transfer PV range
the rated pressure range in transmitter, lower/higher limit is
corresponding to the 4 mA and 20 mA respectively.
mmH O, inH O, inHg, mmHg, kgf/cm , psi, kPa, MPa, Pa,
mbar, bar.
Change PV range (new PV range corresponds to the AO output).
a. Switch to HART function 2 by pressing , as figure 4-5-2-1.
b. As figure 4-5-2-2, press to show the PV range and it returns to the inter-
face as figure 4-5-2-1 by pressing .Switch to function 3 by pressing .
c. Press to switch the PV units.
d. The steps of transfer range's lower limit:
① Pressing once, the digit of lower limit will flash once.
② Input the lower limit value, press to confirm.
③ After the screen shows "_ _ _ _ _ _" for 2 seconds, setup is finished.
e. The steps of transfer range's higher limit:
Pressing once, the digit of higher limit will flash once.
Input the higher limit value, press to confirm.
After the screen shows _ _ _ _ _ _ for 2 seconds, setup is finished.
