What to do if my Fox Thermal FT3 Measuring Instruments unit will not power-up?
If your Fox Thermal Measuring Instruments unit won't power up, begin by inspecting the fuse (F1) located next to TS1 on the main board. Also, verify that the correct power supply voltage is present at TS1 on the main board. If the fuse is intact and the unit still fails to power on, it is recommended to call Fox Thermal for further support.
What to do if my Fox Thermal FT3 meter does not initialize?
If your Fox Thermal Measuring Instruments meter doesn't initialize, electromechanical interference might be the reason. Start by checking the meter's power cycles. Access the Engineering screens by pressing and releasing F1 and F2 simultaneously. Navigate to screen #23 by pressing F1 and note the power cycle value. After returning to normal operation by pressing F4, monitor the meter until the issue reappears. Revisit screen #23 to check for an increase in power cycles, which would indicate that the microprocessor is resetting due to EMI electrical noise. Make sure to check the grounding and routing of both power input and output cables.
Why is the flow measurement erratic or fluctuating on my Fox Thermal FT3 Measuring Instruments?
Erratic or fluctuating flow measurements on your Fox Thermal Measuring Instruments can be due to several factors. It could be caused by: * Very turbulent flow. * A dirty sensor. * A broken sensor. * The probe not being mounted securely. * A malfunction in the flow meter. * Incorrect meter installation. To address this, you can try increasing dampening using the filter settings, cleaning the sensor, or remounting the probe securely. If these steps don't resolve the issue, the flow meter may need repair or re-installation according to the instructions.
What to do if the flow measurement seems low on my Fox Thermal Measuring Instruments?
If the flow measurement on your Fox Thermal Measuring Instruments seems low, it could be due to the probe not being oriented properly or a dirty sensor. Ensure the probe is oriented according to the installation instructions and clean the sensor.
