Frequently Asked Questions

Please review the KJLC 392 on how to check the R&D values of the gauge. If the FVI values are high, please degas and recheck the values. If this doesn’t change the values, measure the pin resistance of the KJLC 392 (instructions in KJLC 392 manual). If these are not within spec, the sensor filament needs to be replaced. If this does not cover the issue you are seeing, please contact
