Major Firmware Update

This release includes both a new function and updated ability.


  • New ‘Tare Save’ function
  • Updated auto-stop detection time

Major Firmware Update

New setting and new battery level display


  • Updated setting ‘Pre-Infusion Time Out’ 
  • New battery percentage display ability 
  • Updated low battery warning message display
Additional firmware updates include:
  • Updated pre-infusion workflow to droplet auto-start modes. To use, set a desired pre-infusion timeout in settings. Then, manually start the timer or let the timer automatically start with the flow. The timer will automatically stop counting when the flow stops.
  • Added ability for scale to show remaining battery power. To access; when the scale is off, press and hold the Power button until ‘Batt’ is shown on the display. It will show after 'SET' appears. The scale will display battery power, e.g. ‘Batt 90’ referring to 90% battery.
  • When the battery is running low but can still last for a while, “LO_BAt” is displayed once when the scale is turned on, but will not be displayed during use. When the battery is running very low, the Lunar will display “LO_BAt”, then automatically power off.
