Entering Programming
• Hold the “continuous” button for five seconds until “GROUP DOSE
SETTING” appears.
• Navigate menus and adjust variables using B1 and B2, use the
Continuous Button to enter and confirm changes.
Setting Tare Time and Stop-Early
• Enter Programming and navigate to SCALE CONFIGURATION.
• Set “Stop-Early”
The “Stop-Early” parameter is an offset, which closes the brew valve
before the target beverage mass is reached. The purpose of this is to
allow for the residual liquid in portafilter to complete the beverage,
without going over. You can easily calculate how many grams early
you should stop by brewing a shot in mass mode, and subtracting your
target from the final mass of the beverage. The difference is a good
starting point, you may need to adjust depending on your flow rate.
• Set “Tare Time”
The “Tare Time” parameter sets at what moment the machine will tare
the cup. The goal is to allow you a few seconds after starting the shot
in which to place the cup on the scale tray. If the cup is placed on the
scale after the tare time, the weight of the cup will be counted toward
the final beverage mass. Also, any coffee that has made it into the cup
before the tare time will not be counted toward the final beverage mass.
Set Group Mode
Enter Programming, select mode per group.
Brewing with “Continuous”
The continuous mode is a manual mode, and will not self-terminate.
• Load portafilter to desired dose, engage in group.
• Start shot using the continuous button, making sure cup is in place
before the programmed tare time.
• The weight of beverage will appear live on the display
as the shot brews.
• Terminate shot manually when desired beverage mass is achieved,
by pressing the continuous button again.
Brewing in Mass Mode
In mass mode, the brew cycle will terminate once a programmed beverage
weight has been reached.
• Enter desired target beverage mass in programming.
• Load portafilter to desired dose, engage in group.
• Start shot using programmed button.
• The target weight will display until the tare time, at which point the cup
weight will be tared.
• The shot will self-terminate when programmed beverage
mass is reached.

Calculating Brew Ratio
(example: 18 grams dry coffee : 36 grams beverage weight or 1 : 2
Brewing in BREWRATIO mode
In Brew-ratio mode, the machine will calculate your target beverage mass by
applying your programmed brew ratio to your measured input dose.
First Enter Portafilter Weight
• Hold G1B2 for 2 seconds until is displayed.
• Wait until is displayed, place portafilter on scale tray, making sure
the lip of the portafilter sits in the crescent shaped cutout.
• This only need to be done once, and applies to all groups.
Enter Desired Target Brew Ratio in Programming
• Load portafilter to desired dose.
• Hold B1 on desired group for two seconds, until is displayed.
• Once the weight of the portafilter is displayed (as a negative value )
place loaded portafilter on scale tray, making sure the lip of the
portafiler sits in the crescent shaped cutout. The keypad will flash once
the dose is recorded.
• Engage the portafilter in the group.
• Start shot using programmed button.
• The target weight will be calculated based on the programmed brew-
ratio and displayed until the tare time.
• The shot will self-terminate when calculated beverage mass is reached.
Checking/Calibrating Scales
Your scales (firmware v1.8) come calibrated from the factory, and do
not need to be calibrated on install. Should you ever need to recalibrate,
follow these instructions:
To Check Calibration:
• Enter mass mode.
• With blind disk in portafilter, engage continuous brewing.
• After [ ] [ ] [ ] stops blinking ~5 seconds 0.0 will be displayed.
• When 0.0 is displayed, place 100.0g weight on scale.
• Display should show 100.0 +/- .1g.
• If scale is outside of range, calibration must be performed.
To Calibrate:
Caution: anytime the drip tray is removed, place blind portafilter baskets in
each group, to prevent water from dripping on electronics.
• Remove scale platforms and drip tray.
• Enter technician level programming, by holding the G1 continuous
button for 10 seconds, until prompted for a password. (Password is
B1,B2, CONTINOUS,B1,B2,CONTINUOUS).
• Navigate to SCALE CALIBRATION> GROUP 1 SCALE CALIBRATION.
• Follow on-screen instructions.
¤ Empty scale, press enter.
¤ Place 100g weight on scale, press enter.
• The display will flash values for three variables: Ratio, Trials and Quality.
Record these values, and compare to the chart below. If any of these
values are outside of the specified range, contact Technical Solutions.
Ratio 350-400
Trials 2-6
Quality The difference between the two number should be <300
