Instruction manual for use of the S5141 logger
The device is designed to measure and record signals from up to three external sensors with
output 0 - 5 Vdc with the possibility to record simultaneously the ambient temperature measured by
the built-in sensor. Sensor connection is realized via terminals. Measured values are displayed on the
two-line LCD display and are stored in selectable time interval to internal nonvolatile memory. All
logger settings and control are performed by means of personal computer and password protection is
enabled. It is also possible to switch ON and switch OFF the logger by start/stop magnet (this function
can be disabled from the PC). Also automatic switch ON at programmed day and time (maximum
one month forward) is enabled. Start/stop magnet enables also to clear the minimum and maximum
value memory.
Minimum and maximum measured values can be displayed (display switches to actual measured
values and min/max values automatically). It is also possible to operate logger with switched OFF
display. Short display of actual measured values is enabled by means of magnet.
Switched ON logger every 10 seconds (independently on logging interval) updates MIN/MAX
memory, compares measured values of each channel with two adjustable limits for each channel and
exceeding of limits is indicated on the display (alarm function). Also memory alarm mode is
selectable, when alarm is indicated permanently till alarm memory reset. Alarm function is enabled
or disabled for each channel individually.
Logging mode can be adjusted as non-cyclic, when logging stops after filling the memory. In
cyclic mode oldest stored values are overwritten by new. In addition logging mode can be selected
when logging is active only if measured value is out of adjusted alarm limits.
Stored values can be transferred from logger memory to the PC by means of communication
adapter. Communication adapter can be connected to the logger permanently – data logging is not
interrupted even if data download appears.
Logger evaluates minimum battery voltage and its drop below allowed limit is indicated on the
display. At the same time value of remaining battery capacity is available by means of the PC program
and appears on the logger LCD in % (every time after switch ON).
