GPD-100 portable gas detector has been developed to prevent accidents beforehand by detecting various leaked
gases occurring in industry fields such as plant, gas storage place, manufacturing process, etc. that produce or use
flammable gas, toxic gas.
GPD-100 portable gas detector displays measured values by detecting gas leakage in areas with risk of gas leakage,
and inform the user of alarm signals using visual and audio signals.
Body of GPD-100 has enclosure made of plastic (Polycarbonate) material.
GPD-100 has Sample pump embedded according to the method where leaked gas is inhaled by using a Pump. The
front face is composed of display unit displaying gas concentration value and alarm situation, port unit inhaling and
exhausting gas, terminal unit connecting USB, has Micro SD Card, and DC Jack. Also, the sensor has a structure of
cartridge form, facilitating easy exchange by the user.

value of High scale, at which time, Alarm 1 value is increased or decreased whenever
"UP" key or
"DOWN" key is pushed.
- If "RUN/MODE" Key is pushed when the desired Alarm 1 value is displayed,Alarm1 value is set and
the next item is entered into.
- Alarm level is set for the concentration specified by domestic regulations upon product shipment.
- It is a mode where the direction for operation of Alarm1 is set, and "1H＂ or "1L"이is displayed
whenever
"UP" key or "DOWN" key is pushed at this time. "1H " mode is the mode operating - when
larger than or the same as Alarm1setting value, while "1L" mode is the mode operating when smaller
than or the same as Alarm1 setting value.
- If "RUN/MODE" Key is pushed when the desired mode is displayed, it is set and the next item is
entered into.
- It is a mode for setting Alarm2 value, with the message being displayed as "AL-2".
- It is a function for changing Alarm1 setting value, where the maximum value is possible up to 90%
value of High scale, at this time, Alarm 2 value is increased or decreased whenever
"UP" key or
"DOWN" key is pushed.
- If "RUN/MODE" Key is pushed when the desired Alarm 2 value is displayed,Alarm1 value is set and
the next item is entered into.
- Alarm level is set for the concentration specified by domestic regulations upon product shipment.

- When "RUN/MODE" Key is pushed for more than 2sec in the state of "Stby" display, menu selection
mode is entered into.
- There is a part for setting password. Input the password by using "UP" key or "DOWN" key.
When "RUN/MODE" Key is pushed, it is shifted to "ConF".
- When "LOg(LOG)" is selected by using "UP" key or "DOWN" key and "RUN/MODE" Key is pushed,
it proceeds to alarm setting mode.
- After "RUN/MODE" Key is pushed in "CtrL" mode, On/ OFF can be set at this time by using
"UP" key
or "DOWN" key.
- If "RUN/MODE" Key is pushed after selection of On, log saving mode operates.
Note 1) Log starts saving from the time where Wait time is completed after "RUN/MODE" Key is pushed
in the state of "Stby" display.
- "AUtO"(Auto) mode is a mode for automatic recording/saving of log, and YES /no can be selected if
"RUN/MODE" Key is pushed. When YES is selected, it operates in Auto mode, measured values and
equipment information are left in the external memory. When No is selected, flow rate is saved by
using
"UP" key or "DOWN" key at this time.
- It shows a type of external memory. If "RUN/MODE" Key, it is shifted to the next mode.
- It shows currently available capacity of the external memory.
If "RUN/MODE" Key is pushed, the whole memory capacity is
displayed.
- When the record saving mode is set as On, "Stby" (Stand by) and the set time is alternatingly
displayed in the state of Stand by . The set time is the same as the time set in "tImE".

Instruction Manual
- It is a mode where the direction for operation of Alarm1 is set, and "2H" or "2L" is displayed whenever
"UP" key or "DOWN" key is pushed at this time.
- "2H" mode is the mode operating when larger than or the same as Alarm1setting value, while "2L"
mode is the mode operating when smaller than or the same as Alarm1 setting value.
- If "RUN/MODE" Key is pushed when the desired mode is displayed, it is set and the next item is
entered into.
6.8. Record saving mode (Log Save Mode)
■ Note1) When the record saving mode is turned On, log is saved when there is SD card.
■ Note2) When a SD card insert with more than 2GB, W-04 Error message is DISPLAYED, with recognition being
not possible.
