Air/Gas Flow Applications
1. Remove the instrument's enclosure cover.
2. Ensure the configuration jumpers on the control circuit are correct for this application. See Tables 3-3
through 3-6.
3. Check to make sure the input power jumpers match the power to be applied to the instrument. See Table 3-2.
4. Apply power to the instrument. Verify the yellow LED is on and allow the instrument fifteen minutes to
warm-up.
5. Verify the mode switch is in the RUN position.
6. Attach a DC voltmeter to the P1 terminal block with the positive (+) lead to position one and the negative (-)
lead to position two.
Note: The terminal block can be unplugged from the control circuit to facilitate easy connections. The terminal
block is used in late production instruments. Early production instruments used a mating cable and
connector. If a cable and connector are required use FCI part number 015664-01 to order.
7. Establish the normal process flow condition and allow the signal to stabilize.
Note: The output signal at connector P1 will vary inversely with changes in the process flow rate. The output
signal level is relative to the type of process media being measured and the heater wattage setting. See
Figure 3-3.
