What to do if Pulsar Imp+i.s. display shows “L0E”?
If your Pulsar Measuring Instruments display shows “L0E”, it indicates that no valid echo is being received, and the unit has entered a fault condition. To resolve this, verify that the material level is within the device's measurement range and ensure the sensor is positioned perpendicular to the material surface.
Why is the material level consistently incorrect by the same amount on my Pulsar Measuring Instruments?
If your Pulsar Measuring Instruments are consistently displaying an incorrect material level by the same amount, verify that the empty level (P105) has been entered correctly.
How to fix incorrect reading on Pulsar Imp+i.s. Measuring Instruments?
If your Pulsar Measuring Instruments are showing an incorrect reading for the current level, measure the actual distance from the transducer face to the surface of the material. Then, enter Program Mode, access the SyS1 menu, go to P21, press ENTER, type in the measured distance, press ENTER, and wait until “Stor” is displayed. Finally, return to Run Mode; the display should now update to the correct reading.
