8.2 Failed Calibration
If calibration has failed, the GLP function will reset the date and time to
zero. The WP-80 still shows the results of the last successful calibration.
For example:
Asy 0.10pH
@ 00/00/00 00:00
Slope 100.0%
@ 00/00/00 00:00
Temp Offset 1.0
@ 00/00/00 00:00
Note that these calibration values are still used if further measurements
are taken without recalibrating.
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. This function is available only when the
optional RS232 port is fitted.
1. Switch the meter on.
2. Ensure that the WP-80 RS232 cable is connected to the instrument
and to the printer or PC.
3. Send the GLP information to the RS232 port
( →→ F4:Setup →→ F3:GLP →→ F3:Print)
4. The GLP information is sent to the RS232 port in formatted ASCII
text. For example…
WP80 V3.5 S1234 @ 31/12/02 12:00
pH Asy= 0.00pH @ 31/12/02 11:40
pH Slope= 100.0% @ 31/12/02 11:50
Temperature Offset= 1.0oC @ 31/12/02 12:00
