How to set Maintenance Mode
※
The operations described in this chapter must not be allowed by general users.
After password has been confirmed, the detector goes into
level1 mode.
Select MAINTENANCE mode by touching “
↑
” or “
↓
” switch.
At this moment, if function key is touched, the detector will go
into submenu of MAINTENANCE MODE.
This mode is to set decimal point of sensor’s cross sensitivity.
(Default value is X.X)
This mode is to set cross sensitivity(0.1~5.0) of sensor.
This value can be adjusted by touching “
↑
” or “
↓
” switch. The
value will increase or decrease by 0.1. (Default value is 1.0)
When ON is set, “SET-UP” will be displayed in the part where
measured value is supposed to be shown and measured value
of gas will be changed to 0%. (4mA output, MODBUS output 0)
When OFF is set, this function will not be available. (Default
setting is OFF)
This mode is to set zero sensitivity of sensor.
The value will be alternatively switched between ON and OFF by
touching “
↑
” or “
↓
” switch. In case of setting to be ON, the
value measured by sensor will be determined as following way.
The value will be set to be 0 if the measured value is in 0-2%
range of high scale value. The value will be deducted by 2% if
measured value is in 2-3.3%. The value will be set to be same as
measured value if the measured value is in 3.3%-100%. (Default
setting is ON)
This mode is to set zero sensitivity of sensor.
The value will increase or decrease by 0.1 when “
↑
” or “
↓
”
switch is touched.
If the measured value is same or lower than preset value, it will
be set to be 0. The value can be adjusted in the range up to
10% of high scale value.
Touch FUNC switch, then the detector’s mode will go to next
mode.
This mode is to set delay time of determining value being
measured. (default value is 0)
