Thanks
for purchase FrSky’s Variometer sensor. This sensor, used in conjunction with a telemetry transmitter/receiver,
is used to indicate the altitude and altitude rate of the item to which it is attache
d. To maximize your enjoyment, and to
ensure proper sensing, please rea
d through this manual thoroughly. We also encourage you to retain the manual for
future reference should the need arise.
· The Variometer sensor is designed for use with FrSky telemetry systems.
Specifications
The Variometer sensor
calculates the altitude from atmospheric pressure. Atmospheric pressure will get lower as you
go up in altitude, using this the sensor will estimate the altitude. An
exact display cannot be performed if atmospheric
pressure changes in weather. The Variometer sensor also can output the Altitude Rate via DA
port.
Altitude Rate formula: (Output DA Voltage – 1.65)/1.65=Altitude Rate speed/10.24.
What’s NEW!
The new Variometer sensor can act as “BRIDGE” between NON-S.Port
FrSky telemetry sensor system
S.Port system.
The S.Port (Smart Port) is designed for the 2
nd
generation of FrSky system, which
is a signal wire full duplex digital
transmission interface provided by FrSky Electronic Co., Ltd. S.Port
makes RC components/device setup much easier
than conventional multi-wire looms. Any S.Port
enabled devices (sensors, sound module, display module, user data
interface that in line with FrSky S.Port protocol etc.) can be plugged in optionally directly.
When Data In port of this sensor connected to FAS (FrSky Ampere Sensor) sensor or
Sensor Hub
convert the data from FrSky Sensor Hub or FAS-100/40 to the S.Port system.
S.Port offers the superior ability with new high precision hub-less sensor and other datas
et: smaller, easier, and faster
(6 times more than conventional “hub system”).
FrSky V8 series and D series receivers DO NOT support Smart Port

Installation
The Variometer sensor is only used with FrSky Two-
Way (telemetry) receivers that offer
(Rx) and/or Smart Port.
Use provided cables to connect the Variometer sensor and other
equipment
1. Connect Variometer sensor to receiver D8R-ⅡPlus/D8R-
XP etc.
Attention: it is similar method to connect Variometer sensor to D4R-II receiver:

Absolute altitude &
Relative altitude
The Variometer output both absolute altitude and relative
altitude
instruction manual to switch between the two.
The relative altitude will start at 0m and it displays the altitude which changed from there.
Even if the altitude of your airfield is high, it will start at 0m and the
altitude difference from the airfield is displayed.
WARNING：
Failure to follow these safety precautions may result in severe injury to yourself and others.
i To utilize the Variometer sensor, connect it to the digital data-
stream port of FrSky Two
with S.Port of other receiver(s).
i
Ensure that the unit is connected properly to the receiver. Failure to do so could result in damage to the sensor.
i
Ensure that the unit is mounted in an area that will eliminate exposure to fuel,
i To ensure that the Variometer sensor
is functioning as desired, please test accordingly.
X Do not fly until inspection is complete.
