This hand held instrument is used to reprogram KELLER PROGRES pressure transmitters (PRO-Series 20, 21, 25 and 41 etc.). It is suited for portable on-site use or laboratory operations in conjunction with a PC.

The PROGRES circuit used in PRO version transmitters allows the important device parameters of Zero, Gain and Thermal Coefficients to be adjusted or reprogrammed.

The KELLER PROGRES circuit has evolved since its launch in '89 and now has more features in its second release (PROGRES-95). The new PP-96 Programmer is used to access all the features of the latest transmitters fitted with the PROGRES-95 circuit. Transmitter output signals can be monitored on an independent test meter (not supplied).

The PP-96 has been designed so that it is also compatible with older KELLER transmitters which use the previous PROGRES-89 circuit. However when used with older transmitters only the reprogramming functions are available.
