3. LCD Indicator

The display can show any measured differential pressure in selected units regardless of
the calibrated range and the values of LRV and URV (within the limits of the
transmitter and display). The display can also be 0 to 100 percent.

If the measured differential pressure is outside the range established by the LRV and
URV values in the database, the display shows the measurement but also continually
blinks to indicate that the measurement is out of range. The current signal is saturated
at either the low or high over-range limit respectively but the display continually shows
the pressure.

Custom flow units for display, including 0 to 100 percent, are used when the
transmitter is in square root mode.

4. Zeroing the Transmitter

Zeroing does not affect the span.
When the transmitter is zeroed to compensate for installed position effect, the
transmitter may have either LRV differential pressure applied (

CAL LRV

) or zero

differential pressure applied (

CAL AT0

). If using a zero-based range, either method

produces the same result. However, if the range is not zero-based, it is advantageous to
have both methods available.

For example, consider a differential pressure transmitter having a range of 50 to
100 psig. If it is not feasible to vent the transmitter to atmosphere for zeroing (or
to bypass the high and low sides for zeroing), it may be zeroed while the LRV
differential pressure of 50 psi is applied by using the

CAL LRV

function. On

the other hand, if the transmitter has been installed but there is no pressure in the
process line yet (or the high and low sides can be connected by a bypass valve), it
can be zeroed while open to atmosphere (or bypassed) by using the

CAL AT0

function.

a. Zeroing with LRV Pressure Applied (

CAL LRV

)

Before using this zeroing function, apply a differential pressure to the transmitter
equal to the value of LRV stored in the transmitter database.

When zeroing the transmitter, the internal digital value of differential pressure is
trimmed to be equal to the value of LRV stored in the database and the mA
(VDC for IDP10-V) output set to 4 mA (1 VDC for IDP10-V).

If zeroing is done when the applied differential pressure is different from the LRV
value in the database, the internal digital value of differential pressure is biased by
the difference in the values but the output is still set at 4 mA (1 VDC for IDP10-
V).

The

CAL LRV

(and

CAL URV

) function should be used when calibrating a

transmitter for a specific range with known input differential pressures applied for
the LRV and URV.

b. Zeroing with Zero Pressure Applied (

CAL AT0

)

Make sure that the applied differential pressure is at zero. This means venting the
transmitter to atmosphere.
