6. Maintenance Check
The Gas Leak Detector is precision measuring equipment. Maintenance in accordance
with the following items is imperative for maintaining performance of the Gas Leak
Detector and ensuring safety.
In case of dropping the Gas Leak Detector or being wet by using under any conditions
other than the normal environment (refer to Precautions in 1. Introduction on page 3 and
Range in 9. Specifications on page 23), perform a daily inspection or request a periodic
inspection (will be charged).
Daily Check
Items to Check
Description
Alarm Function
Remove the Dust Filter (refer to Dust Filter Replacement on page
17), attach the Drain Filter, turn ON the power and complete the
preparations. Then set the gas sensitivity to 1/5 and confirm that the
alarm lamp (red) flashes and the alarm buzzer sounds when
suctioning inspection gas.
After the inspection, turn OFF the power and attach the Dust Filter
and reassemble.
When the alarm sound indicator is being displayed and the alarm
lamp (red) does not flash or the alarm buzzer does not sound,
contact your New Cosmos distributor.
Gas Probe
Check the Gas Probe for any wear or damage which would affect
operations.
If any, replace the Gas Probe.
Filter Element
When the Drain Filter is dirty or wet, or the water or liquid is in the
Drain Filter, clean out the Drain Filter and replace the Filter Element.
(Refer to Filter Element Replacement on page 16.)
Battery charge
If the remaining battery charge is low, replace the batteries.
(Refer
to Battery Replacement on page 18.)
Airtightness
Turn ON the power and confirm that "E-P" (refer to Pump Error on
page 15) is displayed on the LCD by blocking the inlet of the Gas
Probe.
If an error occurs, the airtightness is normal. Press the restart pump
button.
If an error does not occur, the Drain Filter is damaged or the airtight
of diaphragm is damaged. Replace the parts or request repairs.
Periodic Inspection
To maintain the accuracy of the Gas Leak Detector, request a periodic inspection at your
New Cosmos distributor or directly from New Cosmos at least once a year.
