Setting Up the Output Scale
1. Scroll to the desired output scale and press [Enter].
2. Do one of the following:
If you selected Off, the XGS868i returns to the I/O window. Go to Procedure Options on page 27.
•
•
If you selected 0-20 mA or 4-20 mA, and are using a
•
1-Channel meter, proceed to Step 4 below.
•
2-Channel meter, proceed to the next step.
3. Scroll to the desired Channel option (CH1, CH2, SUM, DIF or AVE) and press [Enter].
4. Scroll to the desired Measurement Parameter and press [Enter]. See Table 9 below for a description of the
available options.
5. At Zero, enter a flow rate value for the low end of the analog output range and press [Enter].
6. At Full, enter a flow rate value for the high end of the analog output range and press [Enter].
