IMPORTANT
•Fully Charge the Li-ion battery after installation before first time use by plugging a USB-C
cable into the USB-C charging port on the circuit board. This allows the device to calibrate
and correctly determine the remaining battery charge.
•Always leak test your RAPT Pill by submerging in water prior to sanitising and dropping in
your fermenter
•Only use KegLand approved sanitisers such as StellarSan or Phosphoric Acid.
The battery may come preinstalled in the RAPT Pill Hydrometer. If that is the case you will need to
remove the blue plastic strip which prevents the battery from completing a connection and draining
during shipping.
Battery Installation (If required)
Only use KegLand approved 18650 rechargeable Lithium-ion batteries (KL26734). The RAPT Pill
Hydrometer has been calibrated according to the weight and density of these specific Li-ion
batteries. If non-approved batteries are used this may alter the accuracy of the RAPT Pill hydrometer
meaning that it will need to be re-calibrated.
To install the Li-ion battery unscrew the housing by rotating the coloured half of the housing counter
clockwise. Then follow the (+) and (-) inscriptions on the battery and battery housing on circuit board
to ensure you install the battery in the correct orientation.
Important: Once you have installed the Li-ion FULLY charge the battery before first time use by
plugging a USB-C Cable into the USB-C Charging port on the circuit board. (USB-C cable NOT
included)

CALIBRATION
Your RAPT Pill comes pre-calibrated from the factory. Due to minor tolerance differences, this
calibration can be improved by performing a manual user calibration.
1. Connect your Pill via a USB-C cable to your Mac or PC, or connect your Mac or PC to your
Pill’s Wifi network. Either will open the RAPT Pill Portal automatically.
2. Once the RAPT Pill Portal is open on your browser and your RAPT Pill is connected to your
Wifi network (See ‘How to connect a RAPT Pill to your Wifi’Above), then access the IP
address of the RAPT Pill by clicking on the network that the Pill is connected to in the Wifi
screen.
3. Make a note of the IP address (usually in the form 192.168.0.XXXX).
4. Enter the IP address into your browser (we recommend Chrome). This will open the RAPT Pill
Portal white the Pill is plugged into your Mac or PC with a USB-C cable.
5. Right click the calibration button and select ‘Open in New Tab’. Then do the same with the
diagnostic button to open the Diagnostic screen in a new tab.
IMPORTANT: The RAPT Pill is designed to disconnect from the RAPT Portal once the USB-C cable is
unplugged to preserve battery life. Beginning the Calibration process with prevent this from
occurring. Hence, keeping both the Calibration and Diagnostic screens open allows you to easily
calibrate the RAPT Pill without losing connection to the Portal.
Having the Diagnostic screen open allows you to easily determine angle, temperature etc. via its real
time telemetry which are required for advanced and custom calibration.
For advanced and custom calibration, it is best to have Calibration open in one tab, and Diagnostics
open in another. Note that you may be prompted to press a button to confirm that you wish to keep
the portal open –this is normal.
Once the diagnostic and Calibration screens are open, please assemble your Pill according to the
directions so that it can be removed from the USB and calibrated according to the instructions
below.
There are three ways to calibrate your RAPT Pill.
1: Standard Calibration
Standard calibration is the quickest and simplest method of calibration. It is also potentially the least
accurate. Fill a container of sufficient volume to hold it in suspension with a liquid of known gravity.
It is simplest and easiest to use water. Once the angle reading has stabilised* enter the gravity
(1.000 for water) and hit Calibrate. Wait until the screen indicates that calibration is complete.
Your Pill is now ready to use!
* The angle will never be completely steady, as it is extremely sensitive. Hit Calibrate when the RAPT
Pill has stabilised as much as possible.

2: Advanced Calibration
The advanced calibration mode is recommended for most users
Advanced calibration is also quite quick and easy, and will provide a more accurate result than
Standard Calibration. It is the same procedure as standard calibration, but in addition to water at
1000, have a solution of a known gravity prepared. We recommend using a gravity in the range that
your fermentation will start –1.040-1.060 for typical beers, for example.
As with the standard calibration, place the pill in water wait until the angle has stabilised and then
hit Calibrate. Once that is done, place the Pill in the solution of known gravity and repeat the
process. Once both data points are entered you are calibrated and ready to go!
3: Custom Calibration
Warning! Custom Calibration is for advanced users only. Only proceed if you are comfortable with
spreadsheets and complex curves. If you are working with solutions with gravities higher than 1.080,
then custom calibration is advised.
For advanced calibration, you will need to take readings at various gravity points roughly 10 gravity
points apart, and make a note of the angle of the Pill at each point. We recommend readings from
1.080 down to 1.000, 10 points apart (so, 1.080, 1.070, 1.060 etc). Note that it does not matter if the
gravity readings are not exactly 10 points apart, as long as the gravity reading is correct. Use of a
hydrometer that is known to be accurate is quite important.
To perform the readings, you will need to have the Diagnostics open in one tab, and Calibration in
another. This allows you to see the real time telemetry with the RAPT Pill disconnecting from the
portal. The angle will never be steady, as it is extremely sensitive. Make a note of the reading when
the Pill has stabilised as much as possible.
Once you have sufficient readings, the angle and the gravity need to be entered on an Excel
spreadsheet (or similar such as Google Sheets) as a graph with gravity on the ‘y’ axis and angle on
the ‘x’ axis. The more readings you take, the more accurate this calibration will be. We recommend a
minimum of 6 samples, with 10 or more providing a greater degree of accuracy. Use the Diagnostics
screen for this data –keep the Calibration screen open to prevent the Pill from disconnecting from
the portal.
When you have created the graph, insert a polynomial trend line onto the graph with the degree of
the polynomial being at least one less than the number of data points. If the trend line creates an
irregular curve (such as not passing through the data point at 1.000 correctly or not following a
polynomial shape) reduce the number of data points (ensuring that there are still more data points
than the degree of the polynomial) until the curve matches.
With 10 data points, a polynomial degree between 5 and 8 will typically give the best results.

This is a sample only
Copy the equation of the trend line that is generated once this is done.
Paste this equation into the field provided on the Custom Calibration screen (In Google Sheets, set
your label to Use Equation).
This will look similar to this:
y = 0.0000023109x5- 0.0005741632x4+ 0.0568746764x3- 2.8119846525x2+
71.1087310405x + 265.6578215178
This is a sample only –DO NOT USE THIS EQUATION AS IT WILL NOT BE ACCURATE
Substitute x in this equation with “*angle^” thus:
y = 0.0000023109*angle^5- 0.0005741632*angle^4+ 0.0568746764*angle^3-
2.8119846525*angle^2+ 71.1087310405*angle + 265.6578215178
This is a sample only –DO NOT USE THIS EQUATION AS IT WILL NOT BE ACCURATE
Paste this equation into the field in your Custom Calibration to complete the calibration.
Congratulations! Your Pill is calibrated and ready to go.
