1.4 High Density Gas Detection
If high-density gas is detected, the instrument and any sample hose must be flushed out with fresh air
before installing a new detection tablet. If a new detection tab is installed immediately without flushing
the instrument (and sample hose) out with fresh air, the wrong answer will occur since detection will
start immediately when the new tab in installed. (SEE PRELIMINARY SAMPLE DRAW, STEP 1.7)
1.5 Memory of Stored Gas Detection Results
1.5.1 Checking Stored Data
The past detection results can be displayed by pressing DATA switch when in the detection waiting
condition or detection finished condition.
The detection results will be stored into the instrument memory (up to 99 readings maximum). The
memory can be retrieved by using the UP and DOWN keys. When power is off, the memory is retained.
To return to the detection waiting condition or detection finished condition, press DATA switch again.
When the DATA switch is pressed, the most recent record is displayed.
M05 : HCHO 0.100
The detection result memory can store only the past 99 readings. If the memory is full, the display will
say:
DATA FULL
For deletion of measuring results stored in memory, see the next page.
If there is no stored data, the display will say:
DATA EMPTY
