Instruction Manual
7.1. PROGRAM MODE
PASSWORD
[**]
- Contacting "FUNC" key for 2 sec or longer in Measuring Mode enters Password mode.
- After setting Password using "↑" or "↓" key, contact “FUNC" key.
PROGRAM
MODE
- If password is correct, it enters Program mode.
- By contacting "↑" or "↓" key, mode changes in defined order.
-
( PROGRAM -> CALIABRA. -> ALARM -> SENSOR -> MAINTEN. ->DEVICE -> VERSION -> TEST )
GAS TYPE
[ DEFIN. ]
- Mode that sets gas name type and contacting "↑" or "↓" key changes gas type.
-
(DEFIN. / USER)
- DEFIN. Is acronym for Define and is selected when using built-in setting of gas name.
-
USER is selected when the user directly sets a gas name.
- When a desired gas type is displayed, contact "FUNC" key to set the gas name and enter Program Mode.
GAS SEL
[ COMB. ]
- Mode that sets gas name and contacting "↑" or "↓" key changes gas name.
- When gas type is set to DEFIN., built-in gas names can be selected for use. When it is set to USER,
-
the user shall set gas name using 5 character for use. Characters allowed for use are number, capital
-
Alphabet, space, and period. When position is moved by setting characters, a cursor in black box shape
-
appears as shown in the figure on left.
USER GAS
[■ ]
UNIT SEL
[ %LEL ]
- Mode that sets gas measuring unit and contacting "↑" or "↓" key changes gas measuring unit.
-
( % / %LEL / PPM / PPB ).
- When a desired gas measuring unit is displayed, contact "FUNC" key to set the unit and enter Program
-
Mode.
D-POINT
[ 100]
- Mode that changes decimal place and contacting "↑" or "↓" key changes decimal place.
-
(0.100/1.00/10.0/100)
- When a desired decimal place is displayed, contact "FUNC" key to set the decimal place and enter the
-
next Program Mode.
HIGH SCL
[ 100]
- Mode that sets high scale value that should be displayed for full range. Contacting "↑" or "↓" key
-
increases or decreases the scale value.
-
( 1 ~ 10000 )
- When a desired high scale is displayed, contact "FUNC" key to set the high scale value and enter the
next Program Mode.
PASSWORD
[00]
- It is password setting mode. This password is checked when entering Program Mode.
- Set using "↑" or "↓" key then contact "FUNC" key to set the password and enter the next Program Mode.
7. System Mode
7. System Mode
7.2. Calibration Mode
7.2.1. Zero Calibration
PASSWORD
[**]
- Contacting "FUNC" key for 2 sec or longer in Measuring Mode enters Password mode.
- After setting Password using "↑" or "↓" key, contact "FUNC" key.
CALIBRA.
MODE
- Contact "↑" or "↓" key to select "Calibration Mode".
- Contact "FUNC" key when "CALIBRA. MODE" is displayed to enter Calibration Mode.
- Contact "RESET" key to return to Measuring Mode.
CALIBRA.
[ZERO]
- When “CALIBRATION MODE” is displayed, contacting "FUNC" key selects Zero Calibration.
- Contact "↑" or "↓" key to achieve [ZERO] then contact "FUNC" key to enter Zero Calibration.
ZERO CAL
[ NO]
- Contact "↑" or "↓" key to achieve [YES] then contact "FUNC" key to perform Zero Calibration.
ZERO GAS
[ 0]
- Using a calibration tool, inject clean air or 100% nitrogen into the sensor at a flow rate of 500 mL/min
-
for 1 min. Contact "FUNC" key when measurement is stabilized to automatically perform Zero Calibration.
ZERO >>
[SUCESS]
- When zero calibration is successful, “ZERO SUCCESS" is displayed for 2 sec on LCD display then it
-
changes to "CALIBRATION DATA" Mode.
- When zero calibration is not successful, "ZERO FAIL" is displayed for 2 sec and it changes to
-
"CALIBRATION DATA" Mode.
- ZERO FAIL occurs when sensor input value exceeds 70% of total ADC input range.
ZERO >>
[ FAIL ]
CAL.DATA
[ 0]
- It is a mode to display measurement after calibration and checks whether calibration is successful after
-
performing auto calibration.
- When it failed, it displays "FAIL" and the current measurement in 1 sec interval.
- Contact "RESET" key to return to "Calibration mode".
■ Due to characteristics of the gas detector, minimum 30 min of stabilization time is required and maintenance
condition may change depending on site condition..
