10.4 Instrument Serial Number
In case the serial number that is fitted to the rear of the 90-FLT is removed or becomes illegible, it
is also available on the 90-FLT display.
1. The serial number is displayed at turn-on, for example…
90FLTm V9.0 T1234 (c) 2004 TPS Pty Ltd
Oxygen, Conductivity, TDS, pH, Turbidity
The “m” after the model name is displayed when the Dissolved Oxygen stirrer is enabled.
2. The serial number is displayed when recalling the GLP information (section 10.1).
3. The serial number is included on the print-out of GLP information (section 10.3).
4. The GLP information can be downloaded to a PC using the optional Windows® software (part
number 130086).
10.5 Additional GLP Features
Another GLP requirement is to record the date and time of every reading. The 90-FLT does this for
you when readings are recorded either with the Manual Datalogging function (section 11.2) or the
Automatic Datalogging function (section 11.3).
