1.1 Description
The
CI-23
is a serial portable printer for its connection to a level meter. With this
accessory it will be suitable to obtain maximum performance of this advanced
measurement equipment.
The printer connection allows to obtain, on site, printing for a pre-programmed
measurement sequence. This is a simple and effective way to get an installation archive
for a given place or get documentation related with level measurement, for further analysis.
Several PROMAX level meters incorporate an RS-232C interface, that allows,
moreover to print results, the remote control of the instrument, thus making possible data
collection and control from a personal computer.
The
CI-23
option includes the followi ng items:
* 24 columns serial portable printer CI-23
* mains adapter / battery charger unit for the printer AL-14
* spare ribbon cartridge
* connection cable between the level meter and the printer
* D-25 male-male adapter
* printer case DC-251
* this manual
