2-8
During automatic datalogging the instrument stores the
values of all gas ranges together with the current time
and date at 60 second intervals.
Automatic datalogging can be disabled by a double press
of Switch Two (
). The ‘STORE’ flag will be
extinguished if automatic datalogging is disabled.
Manual Datalogging
Manual datalogging allows the user to store a snapshot
reading at any point, by a double press of Switch Three
(
). This is confirmed by the ‘STORE’ flag being
displayed for 1 second and the buzzer sounding.
Construction
The instrument is housed in a tough, impact resistant,
moulded case made of polypropylene.
The top panel is protected by a stainless steel top plate
covering a toughened glass LCD cover.
The battery cover (Alkaline) / Battery Pack (Rechargeable)
is attached to the main instrument body by means of two
stainless steel hexagonal screws.
The instrument is sealed against dust and water to IP54
standard. The instrument sensors are protected from dust
and water by membrane and cotton filters, when using
probe handle assembly (Part No. 12481). Other probes
with associated filters are available as accessories.
