The session is defined as a series of action of LOLO from Power-ON till Power-OFF. The measured and stored record in a session is independent to the others, whose the time stamp of the first data is always zero. Each session can have different sampling rate. In case of LOLO RACE, LOLO measures the pressure at this time and set it as the reference pressure, that is, zero meter. Because the reference pressure can be varied at each session,this function enable LOLO prevent from gettting negative altitude. The utility, ANALOLO for DOS identify the negative altitude as landing. In order to avoid negative altitude, a new session should be allocated to each flight to get new refeence pressure and should download each time.

Even if the last measuring point is the same as the first point, both two measured pressures at the that point, may be different, because the flight is long and the pressure changes during one flight.

It's also possible to make custom (extra costs) made LOLO with any combination of two from: 0,1; 0,2; 0,3; 0,5; 1; 2; 1.5; 3; 5; 8 sec.

For erasing data on the device, after conecting LOLO with PC Interface cable, you must push and hold the RST bottan and turn on the 4.8 volts power supply. Then LED will begin flushing. The flushing means that erasing is completed. Then PC interface cable maybe disconnected.

Before installing LOLO into fuselage of the model, it it recommended for you to test LOLO functions. Because LOLO and battery have male connector, adapter cable must be prepared.

Upon power-up LED on your altimeter will flash shortly signaling that the Power-On-Self-Test (POST). After POST, the LED will flash continuously in interval 1sec ON/ 1sec OFF. This is initialising phase which allows LOLO to adapt outside environment (temperature, pressure, etc.). Duration of this phase is fixed to 120sec.

1) In transmitter controlled mode, you can start logging altitude anytime on request from your transmitter (using any channel or switch), even underway of Initialization mentioned above.
2) In transmitter independent mode, you can't skip this phase.

When LOLO has just started logging, then you will fly and measure altitude until LOLO is POWER-OFF. This duration is called a session. During one session, there may be one or more flights. A graph will be made for each session.

you will follow up with connecting RS232C interface cable with your PC (RS232C-port). If your note PC does not have RS232C port, please read Section "USB-Serial Converter".

Setting window enable you change communication configuration. You need not change any parameter in this window in usual. After you confirm COM port once, then you need not open it hereafter.

However when you use USB-RS232C Converter you migh have to change COM port number. (See USB-Serial Converter)

If you click Lightning icon, then automatic sequence for download and graph data will be started. The first window in this series, enable you;
1) define basic (offset) altitude. (This offset will be just added to every altitude record),
2) choose to store the data to a different spreadsheet
3) choose where to store new charts
4) select time in minutes or sec at X-axis
After complettion Click "OK". Then PC is ready to download data from LOLO.
