Please read these helpful hints before proceeding with the start-up and commissioning procedure

on the next page.

1. ONICON ow meters are individually calibrated for a particular application. Be sure to

verify the pipe size and location.

2. When measuring analog output signals, remember that current (mA) must be measured

in series, while voltage is measured in parallel. If the 4-20 mA signal is already connected

to a control system, you must break the connection and measure the signal in series.

3. Do not attempt to rotate the electronics enclosure on the stem.

4. Do not connect power to the analog output without rst conrming that it is congured for

loop powered operation. See section 3.5.2.
