  • New aTM type – it is now possible to open and close the automated tablet magazine from the instrument menu
  • Several animated display features for a better overview of active positions

New “Easy Mode” Feature

The new Easy Mode feature is especially relevant for manual instruments like the PTWS 120D. No login or user rights are required to use the new Easy Mode. This new mode is reduced to the bare minimum of necessary entries: simply set a rotation speed between 20 to 250 rpm and to start the heating of the water bath a target temperature from 25.0 °C up to 45 °C. The lift can be driven up and down by pressing the corresponding buttons. The stirring rotation can be started at any time and a timer starts to run, no matter which position the lift head is currently. The possible range of the lift head movement in this mode is from the upper reference position and to the USP 1+2 working position. The option to use the Easy Mode can be activated by the administrator in the setup menu of the PTWS instrument.

How to install

To install the update, simply copy the files to the instrument’s SD card. The update files and more thorough documentation are available from Pharma Test support: Be sure to include your instrument model and serial number in your message.
