9.2 Failed Calibration
If calibration has failed, the GLP function will reset the date and time to
zero. The
WP-80M
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
°°°°
c
@ 00/00/00 00:00
Note that these calibration values are still used if further measurements
are taken without recalibrating.
9.3 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. Ensure that the
WP-80M
RS232 cable is connected to the instrument
and to the printer or PC.
3. Send the GLP information to the RS232 port

4. The GLP information is sent to the RS232 port in formatted ASCII
text. For example…
WP80M V5.2 S1234 @ 31/12/10 12:00
pH Asy= 0.00pH @ 31/12/10 11:40
pH Slope= 100.0% @ 31/12/10 11:50
Temperature Offset= 1.0oC @ 31/12/10 12:00

9.4 Instrument Serial Number
In case the serial number that is fitted to the rear of the
WP-80M
is
removed or becomes illegible, it is also available on the
WP-80M
display.
•
The serial number is displayed at turn-on, for example…
WP80M V5.2 S1234
Meat pH ORP
o
C
where
S1234
is the serial number.
•
The serial number is displayed when recalling the GLP information.
•
The serial number is included on the printout of GLP information.
9.5 Additional GLP Features
Another GLP requirement is to record the date and time of every reading.
The
WP-80M
does this for you when readings are recorded either with
the Notepad function (section 10) or the Automatic Data Logging function
(section 11).
