NOTE
In a low-temperature environment, the operating time is shortened due to the battery performance
property.
At a low temperature, the response of the LCD display may get slow down.
4-8. Performing measurement
Switch the three-way switching valve to the SAMPLING side to start supplying a gas to the detector head.
Wait until replacement of gas inside the detector head is completed. The following table shows gas flow
rates and the time required for replacement at that time for reference.
When replacement of gas is completed, switch the three-way switching valve to the STOP side read the
minimum value in 5 sec after gas supplying stops.
