MEASUREMENT OPERATION
1. Power ON/OFF
Press ON/OFF key more than 0.2 second to turn on
the meter. While the meter is on and electrical power
is enough, the BAT. OK LED will stay on.
To ensure the accuracy, users must perform the
warm-up in the clean air.
The meter will be automatically switched off in 10
minutes. Or you could press ON/OFF key again to
turn off.
!
Please note that the left methane value on 7201
doesn't equal to the right side propane value.
So, make sure the gas you measure then read
the value from the correct side.
2. Warm-up status
While the meter is power on but Ready LED doesn’t
light on, the sensor warm-up is in process. It takes
around 60 seconds and Ready LED is on when it
is ready to measure.
