Step 3. Sensor Validation
1. Select Sensors to continue with sensor validation.
2. Turn off power to the flow meter. If the sensor probe
is flowing air allow a 3 minute cool-down before con-
tinuing. If the probe is on the bench allow a 6 minute
cool-down before continuing.
3. Locate and remove the sensor validation jumper as shown on the
screen.
4. Connect the digital multimeter to the velocity sensor pins. Enter
the measured resistance in Ohms for the velocity sensor in the
dialog box.
5. Connect the digital multimeter to the temperature sensor pins.
Enter the measured resistance in Ohms for the temperature sen-
sor in the dialog box.
6. Replace the sensor validation jumper. Turn on power. The
Smart Interface software returns to the validation screen and in-
dicates the Sensors pass/fail status.
Step 4. Report
1. Select Report. Enter the desired filename and location. To print
the validation report in straight ASCII text form, select the
OPEN FILE button. Use a text editing software printer driver.
To print the Validation Report in a graphics format, select the
PRINT GRAPHICS button.
2. This completes system validation. Click Return to go to the
Smart Interface software main screen.
Warning!
The sensor validation
procedure must be
performed with the
power off.
Caution!
Do not power the flow
meter with the sensor
jumper disconnected.
This could cause over-
heating of the sensor
and/or damage to the
electronics.
