7 Switching possibilities of the GRIMM 190
7.1 With a terminal program
Previous to switching the device it has to be within service mode 0. Therefore a terminal program is
necessary.
Following versions are possible:
Version 7.80
PM10, PM 2.5, PM1 in storage, LCD and via the RS.232 interface.
Version 12.30
31 channels particle counts/ size distribution in storage, LCD and via the RS.232 interface
Switching into service mode 0 following steps are to be done:
- Send the character | (possible by Alt Gr and the key < >, or by Alt 124 on the NumBlock. I.e. the
ASCII code 124 is decimal).
- Press „TAB“
- Press „v“ for control
- Next to the firmware also the date of the firmware has to be visible

initializes after converting.
