HEPF Micro Vario, Altimeter and Variometer

The HEPF MicroVario is a sensitive altimeter/variometer that uses the latest MEMS technology to achieve high accuracy while maintaining miniature dimensions.
The sensor can detect tiny changes in air pressure to indicate the climb/sink rate.

Essential for training with DLG's

Features:

• Tiny dimensions. The sensor plugs directly into the receiver's telemetry port.
• Accurate measurement of absolute/relative altitude and climb/sink rate.
• Automatic telemetry detection: Duplex EX, Hott, MSB, S.Bus2.
• Configurable alarms for altitude and climb rate.
• Configuration via the transmitter
• Firmware updates.

The Micro Vario plugs directly into the receiver's telemetry port. Alternatively, a servo extension cable could be plugged in between the receiver and the Micro Vario.

Telemetry and Settings:

The device is compatible with the JETIBOX and can be used for programming.
The JETIBOX menu is divided into three sections:

1. Actual values - Displays the current telemetry values (altitude, variation, pressure, temperature) along with minimum and maximum values.
2. Reset Min/Max - Press the left + right buttons simultaneously to reset all minimums and maximums.
3. Settings

• Language - You can select the language of the JETIBOX screen.
• Vario Sensitivity - defines the filter amount for the pressure sensor data. Increasing the sensitivity will give you a faster response to changes in altitude. Please note that the indicated noise may also occur. (Default: Medium)
• Sink Rate – Sink rate of the aircraft when there are no thermal effects. The sink rate value is added to the climb rate. This results in more accurate localization of thermal currents.
  Example: If the model flies with a nominal sink rate of 0.5 m/s, the vario is silent. As soon as the model enters a thermal, a beep sounds (although the aircraft may still be sinking).
• Sealevel Pressure – The sea level pressure is used as a reference to calculate the absolute altitude. To get the most accurate altitude calculation, set the pressure at your location to sea level. The International Standard Atmosphere Model defines the sea level pressure at 1013 hPa.
• Round Altitude – Enable or disable the rounding of altitude values displayed on the transmitter. Relative and absolute altitude rounded to full meters, decimal part omitted.
• Altitude Alarm – You can set an altitude alarm. *)
• Vario Alarm – You can set an alarm value for excessive climbing or sinking.*)
• Alarm Interval – defines the time period between alarm announcements.
• Service – In this menu, you can view the device version and reset to the factory default configuration.

*) The alarm setting is compatible with Duplex and Hott systems.
