8.2 Failed Calibration
If calibration has failed, the GLP function will reset the date and time to
zero. The
WP-88 still shows the results of the last successful calibration.
For example:
Lo Zero 1.0NTU
@ 00/00/00 00:00 Hi Span 100.2%
@ 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.
Switch the meter on.
1. Ensure that the
WP-88 RS232 cable is connected to the instrument
and to the printer or PC.
2. Send the GLP information to the RS232 port
(

F4:Setup
→ → → →
F3:GLP
→ → → →
F3:Print )
3. The GLP information is sent to the RS232 port in formatted ASCII
text. For example…
WP88 V2.0 T1234 Probe V1.1 T4321 @ 31/08/11 12:00
Turbidity Low Zero= 1.0NTU @ 31/08/11 11:10
Turbidity Low Span= 100.2% @ 31/08/11 11:20
Turbidity High Zero= 1.NTU @ 31/08/11 11:30
Turbidity High Span= 100.2% @ 31/08/11 11:40

8.4 Instrument Serial Number
In case the serial number that is fitted to the rear of the WP-88 is
removed or becomes illegible, it is also available on the WP-88 display.
•
The serial number is displayed at turn-on, for example…
WP88 V2.0 T1234
Turbidity, Temp.
where T1234 is the serial number.
•
The serial number is displayed when recalling the GLP information
(section 8.1).
•
The serial number is included on the printout of GLP information
(section 8.3).
8.5 Additional GLP Features
Another GLP requirement is to record the date and time of every reading.
The
WP-88 does this when readings are recorded either with the Notepad
function (section 9) or the Automatic Logging function (section 10).
