- Page 2 Instruction manual for use of temperature and RH logger S3121P Logger is designed for measurement and record of temperature and relative humidity of the compressed air. Measuring sensors of temperature and humidity are built-in a probe connected to logger by a cable. Measured values including calculated dew point temperature are displayed on the two-line LCD display and are stored in selectable time interval to internal nonvolatile memory.
- Page 3 Technical parameters: Measuring parameters: Temperature (RTD sensor Pt1000/3850ppm): Measuring range: -30 to +105 °C Resolution: 0.1 °C Accuracy: ± 0.4 °C from –30 to +80°C, ± 0.5 °C over +80°C Relative humidity (reading is temperature compensated at entire temperature range): Measuring range: 0 to 100 %RH Resolution: 0.1 %RH Accuracy: ±...
- Page 4 Communication with computer: via RS232 (serial port) by means of COM adapter or USB port by means of USB adapter; data transfer from logger via communication adapter is optical Real time clock: adjustable from computer, integrated calendar including leap years Error of internal RTC: <...
- Page 5 After connecting the logger to the computer reading of logger info is enabled by means of the PC software and also setting of the instrument accordingly to the user needs (menu Configuration / Setting of instrument parameters). Before logging start it is necessary: check or optionally set the logger real time clock select suitable logging interval select logging mode (cyclic or non cyclic)
- Page 6 Reading on the display in usual operation (logger switched ON) After switching ON the logger all LCD symbols are displayed for checking the display. Then actual date and time in logger is displayed for approximately 4 s. Consequently reading of estimated remaining battery capacity for approximately 2 s is displayed (values 0 to 100%).
- Page 7 Temporary displaying of actual reading by magnet Alarm indication on the display It is necessary to enable alarm function from the PC and set for each quantity lower and upper limit. If measured value is inside of set limits, alarm of proper quantity is not active. If value of measured quantity gets outside of set limits, alarm of proper quantity is active and it is indicated on the display.
- Page 8 If reading BAT is displayed permanently, battery voltage is low and logger is not possible to switch ON. If logger was switched ON before it, data logging is stopped and logger is switched OFF. Communication with computer can temporarily work. Replace battery as soon as possible! Start / stop by magnet The function must be enabled from the PC before.
- Page 9 Battery replacement Low battery is indicated on the display by blinking of reading "BAT". It can be displayed permanently, if battery voltage is too low. Replace the battery for new one. Applied is Lithium battery 3,6 V, size AA. Battery is located under logger lid. Warning: near battery fragile glass reed contact is located –...
- Page 10 APPENDIX A The probe for measuring the moisture of compressed air should be placed directly on the pressure pipelines to achieve higher measurement accuracy and fast response times. But they are cases where such placement is not possible. The reason is the high air speed, high temperature, high pollution, small diameter pipes, etc.
