(2) Average value measuring
Average value can be measured by pressing ＡＶＧ．ＳＴ switch while displaying gas
concentration.
・
Three kinds of measuring time are available,
1 minute ・ 3 minutes ・ 15 minutes .
・
The result of measured average value is memorized after power off.
・
Measuring time is a little bit different from the atmosphere temperature.
・
By starting measuring average value newly, the previous data is cleared, and new
measured average value is memorized. If cancel new average value measuring,
the previous data is kept.
・
In case of over 10,000ppm （Indicates "ＯＶＥＲ"）, the all data is measured
"10,050ppm".
① ７００ ｐｐｍ
（Gas concentration indication.）
Press
ＡＶＧ．ＳＴ
switch.
② １ｍｉｎ：ＳＴＡＲＴ→ＥＮＴ
（Blinking measuring time.）
By ＋ － switches, measuring time can be selected.
③ ３ｍｉｎ：ＳＴＡＲＴ→ＥＮＴ
（Blinking measuring time.）
Press
ＥＮＴＥＲ
switch, start measuring average value.
④
３ｍｉｎ： ８００ ｐｐｍ
（Measuring average value.）
Indicate moment concentration value.
Time count down.
⑤ ５８ｓｅｃ： ８８０ ｐｐｍ
（Measuring average value.）
Change over from "min" to "sec" when the rest time becomes within 1 minute.
⑥ ＡＶＧ．： ８５０ ｐｐｍ
（Measuring average value end.）
Press
ＥＳＣ
switch, return to gas concentration indication. （to ①）
Press
ＡＶ／ＰＫ
switch, change over to peak value indication. （to (4)-③）
Press
ＡＶＧ．ＳＴ
switch, change over again to measuring average value. （to ②）
