  • Page 8: Introduction

    Introduction First of all, we would like to thank you for purchasing our device. Indu Altimeter is an electronic device, which mimics classical altime- ter construction and combines it with the state of the art electronics. This results in the best of both worlds; a perfect and intuitive ana- logue reading combined with high precision of modern electronics.

    The short pointer is working in 10000 m (feet) per revolution with 200 m markings (200 feet). 57 mm has a single pointer and a scale with 500 m (feet) markings. Optionally, the 80 mm Indu Altimeter can be equipped with inte- grated backup battery. (a) 57 mm (b) 80 mm Figure 1: Front and side view with its principal dimensions.

    Table 2: Technical specifications for Indu Altimeter with backup bat- tery. For the rest of the specifications see Table 1. Options Indu Altimeter comes in a few variants regarding scale and backup battery. LCD display can have options, too. 1.3.1 Scale Options The instrument can be delivered with two different scales.

    If the main power is switched off, the instrument obtains power from internal battery for a limited time. In addition, the backup battery in Indu Altimeter can supply power for one low power external device, like Indu Airspeed Indicator.

  • Page 13: Installation

    Altimeter — Manual 2. Installation Installation Indu Altimeter requires a standard size 57/80 mm hole in the instru- ment panel. The position of the hole must ensure good access to the instrument for the QNH adjustments and it must be always visible from the pilot’s perspective.

    Water must not be allowed to enter the tubing. It is strongly recommended to label each tube before connecting to Indu Altimeter. This will help a lot if you ever have to remove and re-install the instrument.

  • Page 17: Illumination

    A device connected to this connector will also get backup power from Indu Altimeter in the case of main power bus failure. This backup power is limited to 150 mA at 12 V, which typically allows connection of one other Indu instrument.

    Write down the altitude shown by the reference. 2. Turn the knob on Indu Altimeter to indicate 1020 hPa (30.12 inHg) and wait for about 3 seconds for a short cyan line to appear on the top of LCD display.

    5. Now a full cyan line appears and the LCD display is slightly altered. It shows the offset and the altitude. Turn the knob until Indu Altimeter shows the same altitude as the reference altimeter. Wait for cyan line to disappear.

    3. Turn the knob to 1013 hPa (29.91 inHg) to complete the pro- cedure. 4. Finally, you need to turn off Indu Altimeter and then back on in order to activate the change. Maintenance & Repair No special maintenance is required.

    11000 meters of geopotential altitude. The thropopause layer is modeled by equation (2) up to 20000 meters of geopotential altitude. As the pressure sensor is calibrated down to 100 hPa (about 16000 meters) altitudes above 16000 meters are not reliable. © Kanardia 2015-2020...

  • Page 24: Altitude Derivative

    Altitude Derivative Altitude calculated from pressure is numerically derived to get rate of altitude change – vertical speed. The derivative is mathematically correct and as such does not introduce any error. We are using multiple point numerical derivation. © Kanardia 2015-2020...

    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 2015-2020...

  • Page 26: Normal Operation

    In order to verify capacity of the backup battery, please follow the following procedure. 1. Run Indu Altimeter on the system bus until the battery is fully charged – wait until the small green rectangle appears on the screen. This indicates that battery was fully charged.

  • Page 27: Connection Schematics

    This option is recommended. Here a single DPST switch is used. This switch allows you to activate two independent circuits. When switch is on, it simultaneously connects Indu Altimeter with the sys- tem bus and activates the backup system. When the switch is off, both circuits are disconnected.

  • Page 28: Solution With Two Switches

    Figure 8: Connection solution with two switches. CAN Bus Power Schematics Each Indu Altimeter has two CAN bus connectors at the back. In the case of backup battery, only one connector provides backup power to other connected instruments. The power is limited to 150 mA at 12V (1.8 W).

  • Page 29: Slave Version

    Slave Version A slave version of Indu Altimeter also exists. The slave version does not have its own sensors and depends on some external master device. The master and slave devices must be connected with CAN bus.
