1. Test of the basic functions 1.1 Switch On functions With the „I/O“ button the LSG/LSK is switched on. All LCD-segments, die red LED, the beep and the LCD lightning are switched on. By pressing the I/O Taste longer this function check will be done correspondingly longer.
1.5 LCD The little point in the lower left corner is blinking in every display mode. The battery symbol is displayed in the mode “Battery display”. 1.6 Battery voltage measurement When inserting new batteries the display must show 13 bars minimum. When using accumulators minimum 10 bars.
2. Start-up 2.1 Warm-up phase After switch on the warm-up phase starts. It lasts between 60 seconds and four minutes. Should the EPROM in the sensor head have no valid parameters the warm-up phase will always last four minutes. The maximum warm-up time will arise when the instrument has not been used for a long time. During warm-up time a running bar can be seen in the bar graph display which is a symbol for the progress of the warm-up phase.
2.7 Operation via the Jack Plug The LSG/LSK can be energised also via the jack plug. The allowed range is 6 to 14 Volt. For switch on the LSG/LSK batteries must be inserted to the instrument. These batteries might even be discharged. 3.
4. Calibration Device LSG and LSK • Before calibration fill up the wash bottle with water (up to middle position between „MIN.“ and „MAX.“) • the very left connection is for the humidity probe and both right connections are for the instruments which should be calibrated humidity probe •...
5. Failure Display Instrument failures will be displayed as bars in the LCD display. By confirming with the “I/O” button the instruments may be operated nevertheless. The failure will be displayed in exchange to the normal display. (bar 14 is the very right one) Failure Discription Failure Discription Failure Discription...
6. Setting of the soldering bridges The board „LSG/LSK CPU completely equipped and programmed“ with the item no. 100517 is completely identical for LSG and LSK. The firmware recognises according to the upper soldering bridges whether it is the LSG or LSK. Via the lower soldering bridges the multiplier for the sensor element is switched.
LSK ( Sensor SB42A) Heater Sensor Soldering points for the 7. Testing Bottle A mixture is made of 40 parts water and one part Ethanol ( Ethanol 652, EG No: 200-578-8 ). Of this mixture 8 ml will be filled in the cotton of the bottle. The closing of the bottle has to be closed to the arrester.
8. Software Update LSG The firmware can be transferred with the Cyclone Pro to the LSG/LSK. The six pin BDM cable has to be used. The cable can be plugged one to one to the vertical plug J1. The energising of the target hardware is done via the Cyclone Pro.
• 6 pin BDM cable • The cable is plugged to the vertical plug. • Press the button menu on the Cyclone Pro • “Select SAP Image“ and confirm with the button menu • select requested image and confirm with the button menu •...
10. Changes at the software version • With software V01 • New characteristics of the software V02: Switch On Notice LSG : Switch On Notice LSK : 1. Normal Operation Even after the warm up phase is finished a new zero point is determined cyclical and the linearization is calculated new when having a positive sensor drift (resistor bigger than to the end of the warm up phase).
