8.2 Failed Calibration
If calibration has failed, the GLP function will reset the date and time for the failed parameter to
zero. The 90-FL still shows the results for the last successful calibration, as shown in the following
example of a failed pH calibration….
pH Asymmetry= 0.10pH 00/00/00 00:00
pH Un-Calibrated F2:Back F4:Next
8.3 Printing GLP Information to the RS232 Port
The GLP information stored in the instrument’s memory can be sent to a printer or PC via the
RS232 port.
1. Switch the meter on.
2. Connect one end of the RS232 cable to the Charger socket of the 90-FL. The battery charger,
optional battery adaptor, or optional solar panel may be connected to the in-line socket on the
RS232 cable, if required.
3. Connect the other end of the RS232 cable to an RS232 Printer, or to the COM1 or COM2 ports
of a PC.
4. Send the GLP information to the RS232 port:
→→ F4:Setup →→ F2:GLP →→ F3:Print
The message “Printing GLP Data” is displayed while sending the data to the RS232 port.
5. The GLP information is sent to the RS232 port in formatted ASCII text. For example…
