Gas measurement: the sensor preheats while the turning-on
countdown. The refresh frequency is 1HZ. Do not charge in the
process of measuring the flammable gas or explosion may occur.
High/low alarm: 4 default values for high/low alarm with 4 forms of
alarm and the alarm voice can be turned off.
Data record: up to 1000 pieces of data recorded allowable. The
default interval of data record is 5 seconds which can be set in the
inL in the set mode. When the interval is set as 0 second the data
record function fails. Delete operation will delete all the data
recorded.
Temperature display: to set the unit as ℃ or ℉, default unit is ℃
Automatic turning off: the unit turns off within 30 minutes if there is
no further operation. Default turning on is this function.
Battery volume: if the volume is the last bar or less it is highly
recommended to charge the unit. It is forbidden to activate the unit
to operate lest the possible measure error or explosion. If the
battery is low it may turn off automatically. Charging time: about 4
hours. Discharging time: about 8 hours.
Calibration of 0 point: it is recommended that the unit should be
calibrated at the 0 point every month or if there is zero shift
occurring to ensure the high accuracy of the measurement (please
be sure that the battery volume is above 2 bars while calibration,
and put the unit in the air for a while after turning on to ensure that
the unit has its body temperature a little bit higher than the
environmental temperature.
Temperature compensation: the data measured is compensated at
the range of -20℃ to 50℃
MAX/MIN/hold reading: press the button to calculate.
Software error: the unit's crash/turn-off indicates the mistake
occurs in process of operation. Press the on/off button to activate
the unit if it is forced shutdown by software.
