7-1 Frequency and items to be checked
7-1-1 Daily maintenance
Self-performed maintenance
1.
Check the flow monitor
Confirm if the ball is above the red line in the flow monitor. If it isn’t above
the line, please adjust the flow rate.
2.
Check if the power lamp is on
The power lamp should be on while the instrument is under operation.
3.
Check the readings on the LCD
The readings should be “0 ppm” if the gas inlet is installed in a gas-free
environment. If it is not “0 ppm” please adjust the zero point (zero
calibration) after confirming there is no target of interference gas near the
gas inlet.
4.
Check if there is any contamination on the filter or anything to block it
Blockage of the outer dust filter is predicted if the flow ball will not go
upwards in flow rate adjusting. Please replace the filter to a new one if the
filter is blocked. If the ball will not move upwards even if the filer was
changed, please check the sampling line. There may be cracks, bends or
something blocking the tube.
