Instruction manual for use of temperature logger S0141
Logger is designed for measurement and record of temperature from four temperature probes
connected via connectors. Measured values are displayed on the two-line LCD display and are
stored in selectable time interval to internal nonvolatile memory. All logger control and setting are
performed from the PC and password is applicable. It is enabled to switch ON and OFF the logger
by delivered magnet (this possibility can be in configuration disabled). It is also enabled to program
automatic start in certain day and time (for one month forward). 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).
Technical parameters:
Measuring parameters of input channels (can be limited by applied probe):
Measuring range: -90 to +260 °C (RTD Pt1000/3850ppm probes)
Measuring range: -50 to +150 °C (RTD Ni1000/6180ppm probes)
Resolution: 0.1 °C
Accuracy of the inputs without probes:
± 0.2 °C from –50 to +100°C
± 0.2 % from reading from +100 to +260°C
± 0.4 % from reading from -50 to -90°C
Accuracy of the instrument with connected external probe is defined by above input
accuracy and the accuracy of connected probe.
Type of compatible probe: based on RTD Pt1000/3850ppm sensor equipped
with ELKA3008 female connector
Recommended probe Pt1000TG8/E (IP67, -80 to +200°C)
Response time of Pt1000TG8 probe (air flow approximately 1 m/s):
t63 < 1 min, t90 < 3 min (temperature step 20 °C)
Measuring interval, alarm evaluation, MIN/MAX memory update and display refresh: 10 s
Logging interval to memory: 10 s to 24 h (20 steps)
Total memory capacity:
for non cyclic mode 32 504
for cyclic mode 28 896
Specified values are maximum possible and can be reached only if record is not interrupted
(since last memory erasing)
