For the electrical properties of the 2 output signals, see Connecting indicating transmitter.
- Select 5 CALIBRATION in the Main menu and enter password if necessary. Select 2 OUTPUTS in the Calibration menu. In the Outputs menu, select 5 mA OUTPUTS.
- Select the mA output, 1 or 2, to get to the
Output menu (as shown in the following figure) where the output can
be configured.
The line at the bottom of the Output menu display indicates the current configuration of the selected mA output, for example, in the following figure the mA Output 1 has been configured to send the concentration reading of Sensor B. Figure 1. Output menu for mA Output 1 
- To change the sensor the selected output is assigned to, select 1 SENSOR in the Output menu.
- To change output source for the selected output, select 2 SOURCE.
Selecting 1 NOT DEFINED ’turns off’ the selected output. - The 3 ZERO value sets the value when the signal is 4 mA. The default zero value is 0.00, the unit depends on the source and display unit set for the sensor in question (and can thus be for example 0 BRIX or 0 °F).
- The 4 SPAN sets the range, which is the
value given when the signal is 20 mA.
Example: If your measurement unit is CONC% and you want to measure the range 15 … 25 CONC%, first choose concentration as mA output source. Then set the zero value at 15 and span at 10. This means that the output signal is 4 mA at 15 CONC% and 20 mA at 15+10=25 CONC%. To change this output to range 10 … 30 CONC%, change zero to 10 and span to 20 (10+20=30).
- 5 DEFAULT OUTPUT sets a mA default output
value that the instrument returns to in certain malfunction situations. The value can be set
to a low or high mA value, for example, 3.0 mA or 22 mA. The factory setting for default
output is 3.4 mA. For a list of malfunctions that are affected, see Diagnostic message priorities.
NAMUR is an international association of users of automation in process industries. The association recommendation NE 43 promotes a standardization of the signal level for failure information. The goal of NE 43 is to set a basis for proactively using transmitter failure signals in process control strategies. Using these failure signals, instrument faults are separated from process measurements. NAMUR NE 43 uses the 3.8 … 20.5 mA signal range for measurement information, with ≥21 mA or ≤3.6 mA to indicate diagnostic failures (see the following figure). With that information, it is easier to detect a failure condition on a refractometer, for example, it clearly tells you whether you have an empty pipe or a failed instrument.
Figure 2. Default mA output values 
- 6 SEC DEFAULT MODE and 7 SEC DEFAULT allow you to set a secondary mA output value for empty pipe (message NO SAMPLE) to differentiate it from the other messages that cause the measurement to revert to default mA. By default the secondary mA output is disabled.
- 8 MANUAL SET allows you to set different
output values to check the output signal. Press the BACK key to return normal output
function.
If you want to turn off the mA output, select NOT DEFINED in the Source menu.
