Page 8: Warning Cases
2-2. Warning cases WARNING Sampling point pressure The gas monitor is designed to draw gases around it under the atmospheric pressure. If excessive pressure is applied to the gas inlet and outlet (GAS IN, GAS OUT) of the gas monitor, detected gases may be leaked from its inside, thus leading to dangers. -
Page 9: Precautions
2-3. Precautions CAUTION Do not use the gas monitor where it is exposed to oil, chemicals, etc. Do not submerge the gas monitor under water on purpose. Do not use in a place where the gas monitor is exposed to liquids such as oil and chemicals. ... - Page 10 CAUTION Others Pressing buttons unnecessarily may change the settings, preventing alarms from activating correctly. Operate the gas monitor using only the procedures described in this operating manual. Do not drop or give shock to the gas monitor.

Page 26: How To Detect
4-5. How to detect In the detection mode, put the gas sampling probe close to the detection area and take the reading on the display. Display example <- Display example concentration: 0 %LEL concentration: 20.9 % CO concentration: 0 ppm S concentration: 0 ppm Time: 9:30... - Page 27 CAUTION Before performing gas detection, attach the gas sampling probe provided with the gas monitor to prevent disturbances by air dust. When you measure concentrations of oxygen in inert gases for a long time, the carbon dioxide concentration in the air must be 15 % or less. When you use the gas monitor in the air with a carbon dioxide concentration of 15 % or higher, perform measurement in as short time as possible.
- Page 28 <Manual Memory> Any instantaneous value during measurement can be recorded. Up to 256 points of data can be recorded. When the number of recorded data points reaches the maximum, recorded data will be overwritten, starting from the oldest data. (1) In the detection mode, keep the ▼/RESET switch pressed and press the ▲/AIR switch to prepare for recording (about one second).
