● Air adjustment

Air adjustment (zero / 21% adjustment ) is completed when the gas concentration
display changes from a blinking display to a steady display of "0" or "21.0".
（Gas concentration blinking）（Gas concentration steady display）➡

If the TWA concentration (see “Glosary” on page14) exceeds the alarm setting level,"the gas concentration" and "AL. tc" are displayed alternately while the alarm lamp
blinks.
Press the [T x C] switch to cancel the TWA concentration alarm. Note that"gas concentration display" and "AL. tc" will continue to be displayed alternately until
the power is turned oﬀ.

５．Troubleshooting
Display

When the target gas is O , check that the blinking "23.0%" isdisplayed during air adjustment. When the sensor approaches
the end of its lifetime, a value less than 23.0% is displayed.
Replace the oxygen sensor with a new one before the value
reaches "21.0%".

For simultaneous alarms, priority for alarm activation is ①
Second stage alarm, ② TWA concentration alarm, and ③ First
stage alarm.
When the gas concentration display exceeds the service
range, the service range upper limit and “OL” are displayedalternately.

● First and Second stage alarm

If the gas concentration exceeds the ﬁrst or second stage alarm concentration
setting level, alarm activation is accompanied by sound and vibration and the gas
concentration display, alarm display, and alarm lamp blink.

Note

Be sure to execute the air adjustment in clean air.
Accurate gas detection results cannot be obtained if theadjustment is made in an atmosphere mixed with gases.
Execute the air adjustment at least once a day.
In addition, make the air adjustment when the work
environment (temperature or humidity) changes because thezero point may shift.

４．Replacing Battery

→

➡

➡

When inserting the battery, match the polarities (+ and -) withthe battery marks.
If the battery polarity is reversed the detector cannot be turnedon and a continuous vibration may occur depending on
the battery type. Remove the battery promptly and insert itagain with the correct polarity.
This product uses a very small amount of current even after
turned oﬀ to stabilize the sensor. Keep the battery in the
product even when the product is not being used.
If the battery is removed from the product for a long period of time,
initial stabilization of the sensor may take longer, causing an error. In
such a case, insert the battery and leave the product with the power
being oﬀ for one day or longer before use.
― 10 ―

Check alarm sound, alarm lamp,vibration and LCD work properly when
the detector is turned on. If not ,request repairs.

2) Alarm function
Check the alarm indications such as alarm sound, alarm lamp and vibration byhaving the detector draw gas at a level that slightly exceeds the alarm level.
In the event of an abnormality in the way the gas concentration readings
change, such as the alarm lamp does not ﬂicker or the buzzer does not soundrequest repairs.
3) Remaining battery level
Check the remaining battery level of the gas detector.
If the remaining battery level is low, replace the battery.
（See ”Replacing Battery” on page 10）

Note

Alarm activation and use at low temperature may
shorten the battery life.

4) Gas detection intakes
Check that the gas detection intakes A and B are not blocked and the ﬁlter
elements are clean and dry. Replace the elements if dirty or wet.
(See “Replacement Parts” on page 5)（ ） Periodic Check

６．MaintenanceThis product is a precision instrument. Please perform the periodical checks andinspections below to maintain the detectorʼs performance and ensure safety.
In the event of a failure to follow the safety precautions (page 2), such as impact shockfrom dropping or exposure to water, or use in conditions outside the speciﬁcations(page 13), such as usage in temperature/humidity exceeding the speciﬁed range,
please contact New Cosmos or your New Cosmos representative for inspection.
A comprehensive description of the current situation would be appreciated when you
contact us.

Check the product accuracy at least once a month and perform gas calibration
at least once every 6 months. It is recommended to contact New Cosmos or
your New Cosmos representative to perform a periodic inspection including
sensor replacement at least once a year (fees apply).
Quick accuracy check can be performed with test jig (EG-105) and gas calibration
can be performed with gas calibration kit (EG-106) by the customer (see page 5).

― 11 ―The peak value memory function can provide the elapsed timeback to 99 hours 59 minutes ago. Beyond 100 hours, “100H” and“OL” will be alternately displayed in the sub screen and the elapsed
time will not be displayed. The time error is±5%.
Pressing the [Air Adjustment] switch while the detector is oﬀ candisplay the last peak value. However, turning on the detector will
reset the peak value to 0ppm (21.0% for oxygen).

Note

Press the [Power (PEAK)] switch to display PEAK.
The highest concentration value (lowest for O₂)
marked during PEAK being displayed will remain
displayed. To reset the value and return to thenormal screen, press the switch again.

If the operation switches or displays do not operate properly other than whenalarms are activated as described above, remove and reinsert the battery into the
product. Turn on the detector to check performance. If normal operation cannot
be restored with this procedure, request repairs.

Explosion-proof structure:

Intrinsically safe (IS) structure: Structure tested (e.g., spark test) to not become an
ignition source in a ﬂammable atmosphere due toan electrical spark or hot surface during normal
operation and fault conditions.
Non-hazardous area:

Area in which an explosive atmosphere is not expected
to be present in quantities such as to require special
precautions for the construction, installation and useof equipment

Air adjustment:

Adjusting the zero point (or 21.0% for oxygen) in clean air.

Service range:

A range of target gas concentrations the detector is able
to indicate, which are usually outside the Detection Rangeand used only as reference.

Time weighted average (TWA): Concentration value expressed as the product of gas
exposure time (hour) and gas concentration (ppm).
For this detector, it is calculated by dividing the average
concentration per minute by the integrated value of
60 minutes. Note that there is an error of ±5% in thetime calculation, and the unit is "ppm" just for convenience.
Example: When continuously exposed to 100 ppm CO for
30 minutes, 100 ppm x 30/60 = 50 ppm-h.
Gas calibration:

Adjusting the indicated values by using span gas.
Also called “span adjustment”.

Clean air:

Air free from target or interfering gases, and composedof 20.9-21.0vol% oxygen in dry conditions.
