Maintenance
This product is a precision instrument. Please perform the periodical checks and inspections
below to maintain the detector’s performance and ensure safety. In the event of a failure to
follow the safety precautions (pages 6 to 8), such as impact shock from dropping or water
ingress inside the detector, or use in conditions outside the specifications (pages 48-52),
such as usage in temperature/humidity exceeding the specified range, please contact New

Check that all segments (all letters and icons) are displayed on the
LCD. (“Power on” on pages 14-15)
Alarm function

(“Alarm Test” on page 33 for the procedure)
Alarm test
using actual gas
Prepare test gas that slightly exceeds the alarm set value. Let the
detector sample the test gas and check for alarm operation.
Check whether the reading changes and when it reaches the alarm set
value, the alarm light blinks red and audio alarm starts. If the reading
does not change properly, the alarm light does not blink, or the audio
alarm does not sound even though mute is off, contact New Cosmos
or your New Cosmos representative for inspection.
Gas sampling tube
Check that the tube is securely connected to the gas detector.
Check that the tube is free of wear or damage that may interfere with
operation. Replace it with a new one, if worn or damaged.
Drain filter
or
Cooling drain filter
Check that the filter element inside the drain filter is clean and dry.
Replace the element with a new one if dirty or wet.
Check that water is not present inside the drain filter. If present, remove
it and make sure that the drain filter and filter case are completely dried
and cleaned.

Filter element
Battery level
Check the battery level indicator at the top-right corner of the LCD. If
the battery level is low, replace/charge the batteries.
“Battery Replacement” and “Charge Batteries” on pages 38-40.
Airtightness
Turn on the detector. Cover the
gas sampling tube’s probe nozzle tip
with finger. Check that the “Pump Error” is displayed on the LCD. If
displayed, then the operation is normal. Press the
▶
button to resume
the pump operation.
If “Pump Error” is not displayed, airtightness is not good. The gaskets
may be missing or damaged, gas sampling tube may be worn, or pump
failure may occur. Replace them with new ones or contact us for repair.
When used at low temperature, the battery life will be
shorter than when used at room temperature due to the
battery’s characteristics. It is recommended to have
spare batteries, or replace/charge the batteries earlier.
When using rechargeable batteries, it is recommended
to charge them earlier when is displayed.
