Page 7: Introduction
Display is divided linearly in 360 scale. The large pointer is working in 1000 m (feet) per revolution with the 20 m markings (20 feet). Older models do not have push knob and a separate external knob is needed to adjust the brightness. © Kanardia 2015-2018... -
Page 8: Options
LCD display can have options, too. 1.2.1 Scale Options The instrument can be delivered with two different scales. One scale is in feet and the other scale is in meters. The scale must be specified at the time of order. © Kanardia 2015-2018... -

If the main power is switched off, the altimeter obtains power from internal battery for a limited time. In addition, the backup bat- tery in altimeter can supply power for one low power external device, like airspeed indicator. © Kanardia 2015-2018... -

50 hours, 1 sec interval Communication CAN bus, 29 bit header, 500 kbit, Kanardia protocol Table 1: Basic technical specifications. When altimeter is equipped with a backup battery, some specifica- tions from the table 1 are different and correct specifications are listed in table 2 on page 9. -
Page 11: Installation
The instrument is mounted using three screws type M4. To prevent internal stresses, please make sure that the instrument panel is flat. It is highly recommended that the instrument panel is mounted using rubber shocks, which reduce the vibrations. Figure 2 illustrates the mounting hole. © Kanardia 2015-2018... -
Page 12: Connections
It is highly recommended to keep the static tubing as short as pos- sible. The tubing must avoid sharp bends and twists. The tubing must be airtight. Water must not be allowed to enter the tubing. © Kanardia 2015-2018... -
Page 13: Can Bus Connection
CAN Bus Connection Connection to the CAN bus is optional and is not required for the normal operation. Use standard RJ45 ethernet cable to connect it with other Kanardia equipment. When connected to the bus, altimeter will transmit altitude, QNH and vario to other units connected to the bus. -

Connect supplied connector at the back of the altimeter. The connec- tor has a notch on one side, which protects from wrong orientation. Connect blue lead to negative (ground) terminal and red lead to positive (+12-24 V) terminal. © Kanardia 2015-2018... -

A minor sensor offset may be required in order to adjust the instru- ment according to some other reference intrument. Please, follow the steps given below in order to make the adjustment. A precise reference instrument is needed in this procedure. © Kanardia 2015-2018... -
Page 17: Airspeed Adjustment - Auto Zero
CAN bus, you can use altimeter to issue zero cal- ibration command on the airspeed indicator. Normaly, this is not needed. You should issue this command only, if airspeed indicator shows significant offset during pitostatic test. © Kanardia 2015-2018... -

If current unit does not suit you, you can change it by following procedure: 1. Turn QNH until it shows 1020 hPa (30.12 inHg) and wait for about three seconds for a short cyan line to appear on top of LCD display. © Kanardia 2015-2018... -

3. Turn the knob to 1013 hPa (29.91 inHg) to complete the pro- cedure. 4. Finally, you need to turn off the instrument and then back on in order to activate the change. © Kanardia 2015-2018... -
Page 20: Backup Battery
70% – 100% capacity is available. A flashing arrow indicates that the backup battery is being charged. Capacity symbols are the same as above. Small green rectangle - battery is fully charged and it is in stand-by mode. © Kanardia 2015-2018... -

5. You can stop measuring when you reach 30 minutes. Altimeter has internal protection, which will disconnect the battery once the voltage in the battery is critical low. This prevents perma- nent damage of the battery. A completely depleted battery should recharge in about 2.5 hours. © Kanardia 2015-2018... -
Page 22: Connection Schematics
When master is off and this switch is on, then altimeter will run on backup only (case 3). This combination can be used to perform the capacity test. Important: Use a switch with 1 A DC rating or more. © Kanardia 2015-2018... -

The power is limited to 150 mA at 12V (1.8 W). Typically, IAS indicator is protected with the backup battery from altimeter. Connection schematic for such case is shown on the figure 7 on page 22. © Kanardia 2015-2018... -
Page 24: Sensor Calibration
This means that each altimeter is calibrated against 13 · 11 = 143 different temperature - pressure pairs. The least squares method is then applied on this results in order to obtain corrections coefficients. © Kanardia 2015-2018... -
