L2. ANALOG RETRANSMISSION SCALING: FULL SCALE VALUE
The display alternately shows
Ar. F.S.U.
(Analog Retransmission Full Scale Value) and a numerical
value. This parameter establishes the upper limit for the analog output; only the numerical value is
shown during modification. Resolution and decimal point position are as selected for the readout
value.
L3. ANALOG RETRANSMISSION FILTER
The display shows
rF
followed by:
OFF
for no filter on retransmitted value, or
xxx
for filter having the time constant chosen in step C.
Press F to lock in the parameter.
At this point the configuration procedure is complete and the display will return to showing
COnF
.
If necessary, you may now select the analog output calibration procedure by pressing ▲. Refer to
Analog Output Calibration, below.
When configuration/calibration is complete, remove the unit again, place the Mode Selection switch
in the “normal” (closed) position, and replace the unit. See Mode Selection, page 15.
Proceed to Operating Mode, page 21.
4.8 ANALOG OUTPUT CALIBRATION
Press ▲ to toggle the display from
COnF
to
CAL
, initiating output calibration mode.
Press ▼ to display the software version number.
Press F to initiate the calibration procedure, starting at the first parameter.
Press R to initiate the calibration procedure, starting at the last parameter.
Perform the calibration procedure in accordance with the jumper settings to select:
• Current Output, or
•Voltage output.
The jumper locations for these output selections are shown in Figure 6. When the display shows
CAL, you can also load the default parameters, shown on page 24.
To calibrate the analog retransmission output, connect a multimeter, set to the proper measurement
range, to terminals 21 and 22. Press the F key to reach desired parameter then make output
adjustments by pressing ▲ or ▼ until the signal output measured by the multimeter reaches the
proper value. The display only shows the number of counts for the digital to analog converter.
C6 - Retransmission current output minimum value - adjust to 50.0 mµ
C7 - Retransmission current output maximum value - adjust to 20.0 MA
C8 - Retransmission voltage output minimum value - adjust to 0.00 VDC
C9 - Retransmission voltage output maximum value - adjust to 10.00 VDC
