Introduction
The Heatmanager Pro uses 3 internal battery backup (retain values when power has been
switched off) memory buffers for storing the temperature measurements.
The configured sample rate is used to store the measurements into these buffers, so all buffers
use the same sampling rate.
How the recorder function starts and stops can be adjusted in the recorder start-stop menu item.
Here the recorder can be switched always on, or just started when one of the channels that is
configured as a programmer is started. This is used for all 3 buffers.
Internal 4032 position FIFO memory backup buffer
4032 measurements FIFO (first in, first out buffer):
This buffer runs around, so every time the last value is deleted and the newest one is inserted.
This buffer has a total size of 4032 measurements. The total time that can be covered with this
is calculated from the configured sampling time and shown on the bottom of the data menu.
With the export data to usb function in the data menu
all
the contents of this buffer are stored on
the
\SAMP08
directory on the
USB-stick.
Internal 100 position memory backup buffer for USB stick
This buffer takes 100 measurements and after that the 100 new measurements are added to
the existing .csv file in the
\SAMP08
directory on the
USB-STICK
. This is only active/possible
when an usb-stick is inserted. After the auto write procedure the 100 position buffer is automati-
cally cleared and a new set of 100 measurements are taken.
Internal 100 position memory backup buffer for SD-card
(4301TAD screen only)
This buffer takes 100 measurements and after that the 100 new measurements are added to
the existing .csv file in the
\SAMP15
directory on the
SD-CARD
. This is only active/possible
when an usb-stick is inserted. After the auto write procedure the 100 position buffer is automati-
cally cleared and a new set of 100 measurements are taken.
Note: the USB-stick has priority over the sd-card. So when both an USB-stick and
SD-card are inserted, the auto write to .csv file uses the USB-stick. This can
manually be changed over to the sd-card in the csv auto write menu item of the
data menu
Note: before removing the usb-stick or sd-card, first verify that the auto CSV write
procedure is not active on the main-menu\data menu\CSV auto write screen and
stop it before removing the device so the last measured values can be added and
the device can be closed.
Failing to do so can result in a damaged usb-stick or
sd-card with loss of all data.
