Setting Field Baseline for In Situ Zero CAL-CHECK
™
Tests
After calibration of every FT3 meter, a lab technician sets the factory baseline for Zero CAL-CHECK
™
tests. If you are planning on removing the meter from the process to perform the test, you do not
have to set the baseline; however, if you plan to perform the test in situ (in the pipe) or using a Fox
Thermal retractor, you must set the eld baseline before performing the test.
When the sensor is isolated in zero ow, the FT3 meter is ready to either perform the Zero CAL-
CHECK
™
test or set the eld baseline for future tests.
Starting the Field Baseline Set
After the meter has been installed and wired correctly (see Wiring section of this manual), power on
the meter.
The meter should default to display #1. Press "F1" to program the meter. Press Yes (F1) to set
parameters and you will be prompted to enter the password. Use a Level 2 password (9111). The
