Configuration - Omega PX2088 User Manual

NOTE
If you are using a transmitter that has a white plastic electronics cover, perform the
following procedure to replace it with a local indicator. If you are using a transmitter
that has a black plastic electronics cover, proceed to Step 4
.
a. Gently remove the output board from the microprocessor board.
b. Completely remove the two captive screws from the white plastic
cover and the output board. Carefully remove the plastic cover
from the output board.
c. Carefully reattach the output board to the microprocessor board,
taking care to correctly align the screw holes and all
interconnecting pins.
Continue with Steps 4 through 6 to complete the installation.
3. Attach the local indicator to the output board, taking care to correctly align
the selector switch and potentiometer with the appropriate holes on the local
indicator. Also, make certain the interconnecting pins near the top of the
output board mesh correctly with the rear of the local indicator.
4. Tighten the two captive screws and install the LCD meter cover.

CONFIGURATION

Before configuring the indicator, make sure the transmitter output is set to the
desired calibration.
NOTE
The local indicator option does not allow access to the test terminals on the output
circuit board. To measure the transmitter output during calibration, connect an
ammeter to the test terminals in the terminal compartment of the electronics
enclosure (Output Code A). For additional information, see "TEST TERMINALS" on
Page 3-2. For Output Code M transmitters, connect a voltmeter between the "–" and
"V out" terminals in the electronics compartment.
During transmitter calibration, the local indicator display becomes inactive. The
display will indicate "ZERO" or "SPAN," depending on the position of the transmitter
selector switch. Refer to the ammeter reading for calibration of the transmitter
output.
For transmitter calibration procedures, See "Zero and Span Adjustments" on Page
3-3.
