1.5.2 Deleting the Memory of Stored Detection Results
To delete the memory:
While in the data display screen described above in 1.5.1, press the START + DATA switches
simultaneously. The message to delete the stored detection results is displayed.
Then, when START switch is pressed, all the stored detection results are deleted.
If DATA switch is pressed instead, the instrument will return to the previous condition without
deleting the data.

1.6 Battery Voltage Check
By pressing DATA switch for 3 sec while in detection waiting condition or detection finished mode,
the current battery voltage can be checked. If 20 seconds elapses without any switch being pressed
while in the battery voltage check screen, the instrument will return to the state it was in, either
detection standby condition or detection finished mode.
To return to the detection waiting or detection finished mode, press DATA switch again.

1.7 Preliminary Sample Draw Mode
When detection gas mode is changed, or if a high gas concentration was last detected with the
instrument, it is possible the next gas detection test will be influenced by high-density gas
remaining inside the instrument. To prevent this, it is necessary to flush the instrument using the
preliminary sample-drawing mode.
•
It is impossible to delete an individual detection result.
•
All detection results are deleted simultaneously, and once deleted they are
not recoverable.
