8.3 History Mode
In History mode all data collection and transfer is controlled by the dual
stage trigger operation. In summary, the
T1
position is used to align the
instrument on the chosen target and the
T2
position is used to generate the
logged data.
With the trigger pulled to the
T1
position, operation is exactly the same as in
Classic mode. All four temperature types (Peak, Continuous, Average and
Valley) are displayed with the selected (highlighted) type being displayed
internally within the viewfinder as well as being streamed at 0.5 second
intervals to the
Bluetooth
output.
If the trigger is pulled to the
T2
position, this is confirmed by a single ‘blink’
on the internal viewfinder, coupled with a single ‘beep’ on the sounder
(if switched on). When the trigger is pulled to the
T2
position, both the
viewfinder and side displays are ‘frozen’ and a ‘packet’ of data is generated
and sent out for data logging. This packet of data comprises the overall
peak, last continuous, overall average and overall valley temperature
measurements taken during the time that the trigger was pressed to the
T1
position. The emissivity set point and window compensation indicator value
in use are also output, as part of the data packet.
The temperature components of this data packet are also retained within the
instruments memory and may be viewed on the side display by going into
Menu mode and re-selecting twice on the History mode icon.
Note that further data packets will only be added after each press of the
trigger to the
T2
position and the data added will be the measurements
made at the
T1
position during the time preceding the press to
T2
. Any
measurement made at the
T1
position without going to the
T2
position will
not be stored.
If additional data is added, any higher peak (or lower valley) temperature
recorded will overwrite the earlier stored value. The new average value
will then become the average over all stored data and the continuous value
displayed will become an average of the last continuous values for each data
packet within the overall stored sets.
When the stored data set has been inspected the user has the option of
deleting the data by selecting the ‘waste basket’ icon, or exiting the data set
without deletion (exit icon) in which case further data may be added to the
stored set.
Note
If the instrument is switched off, all stored data will be lost.
