IE-LOG-S0541-03
Instruction Manual for use of S0541 logger
Instrument is designed for measurement and record of temperature from two external
temperature probes and two external voltage signals 0-5Vdc. Temperature probes and voltage
signals are connected by means of connectors. Measured value of temperature and actual values of
voltage inputs are displayed on dual line LCD display and are stored in adjusted time interval to
internal non-volatile 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).
Technical parameters:
External temperature probes (can be limited by concrete applied probe):
Range of measurement: -90 to +260 °C (RTD Pt1000/3850ppm probe)
-50 to +150 °C (RTD Ni1000/6180ppm probe)
Resolution: 0.1 °C
Accuracy temperature inputs without probe (Pt1000 and Ni1000):
±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.

with ELKA3008 female connector
Recommended probe Pt1000TG8/E (IP67, -80 to +200°C)
Response time of N1ATG8 probe (air flow approximately 1 m/s):
t63 < 1 min, t90 < 3 min (temperature step 20 °C)
Voltage inputs (IN3, IN4):
Range of measured voltage: 0 to 5 V dc
Effective resolution: 13 bits
Measurement accuracy: ±0,2 % FS
Input resistance: approximately 100k Ohms
