900-C Conductivity, TDS, Resistivity, Ratio, Meter - TPS

8. Good Laboratory Practices (GLP)The 900-C keeps a record of the date and time of the last Conductivity, TDS, Resistivity, Ratio andTemperature calibrations as part of GLP guidelines. The calibration data for k=0.1, k=1.0, k=10 anduser k factor sensors are all stored separately.8.1 To recall GLP information on the display1. Switch the meter on.2. Select the GLP menu ( → F4:Setup → F3:GLP).3. Select F1:Recall from the menu.4. The instrument model, firmware version number, and instrument serial number are displayed,along with a prompt describing how to scroll through the GLP information.900C V3.0 R1234 @ 31/12/98 12:00F4:Next5. Press the key to sequentially scroll through the GLP information for all parameters. Pressthe key to scroll back to previous data. The sequence of information displayed is shownbelow.
