Pc-Assisted Data Logging - General DT8852 Manual Del Usuario

Once Record mode has been entered, one brief press of the REC
button switches the primary readout to show the highest temperature
recorded since entering Record mode, along with the term MAX above
it. The relative time at which this maximum temperature occurred is
indicated by the time shown in the lower right corner. The secondary
readout will continue to show the real-time temperature sensed by the
T2 thermocouple (DT8852 and DT8856 only).
A second brief press of the REC button switches the primary readout
to show the lowest temperature recorded since entering Record mode,
along with the term MIN above it. The relative time at which this
minimum temperature occurred is indicated by the time shown in the
lower right corner. As before, the secondary readout will continue to
show the real-time temperature sensed by the T2 thermocouple
(DT8852 and DT8856 only).
A third press of the REC button releases the primary readout to resume
showing the real-time T1 temperature, with the secondary readout
continuing to show T2 (DT8852 and DT8856 only). The relative time
clock will continue to run and indicate how long it has been since
Record mode was entered.
To exit Record mode, stop the relative clock, and resume "normal"
display mode—with T1 shown on the primary readout and T2 on the
secondary readout (DT8852 and DT8856 only)—press and hold the
REC button for at least 3 seconds.

PC-ASSISTED DATA LOGGING

Although the DT8852, DT8855 and DT8856 lack internal memory, they
can be used as data logging instruments (in order to make multiple
temperature measurements over time at a user-specified sampling
rate) by connecting them to a PC via an optional hardware/software
package. The package, designated ASFTKIT, comprises an RS-232 to
USB converter/cable and a mini-disc containing PC interface/data
logging software.
ASFTKIT includes a user's manual with instructions for connecting
the DT8852, DT8855 and DT8856 to a PC through the instrument's
RS-232 port (Fig. 1, Callout C). The manual also includes complete
instructions for setting data logging parameters such as sampling
time. Although the software was written before the debut of
Windows7, it works well with that operating system and its recent
predecessors. The only change that you may have to make to use the
