GFPIII operation manual Opti-Sciences, Inc.
Diagnostics Menu
Instrument operational values are shown here. This information can be useful for checking system
functionality. In the event of trouble, the readings can be given to a service person.
The top box shows current system values. The Signal reading is a measure of the fluorescence intensity
detected. The Ref reading shows the source feedback amplitude. Batt displays the battery voltage. When
the unit has NiMH batteries installed, a voltage of less than 2.20V indicates that the charge in the battery
is almost used up. A freshly charged set should be installed before beginning a new round of
measurements. A voltage greater than 2.50V is recommended for alkaline batteries. The Temp
(temperature in degrees F) and Bias (Voltage) readings display detector environment values.
The middle box shows preprocessed signal (raw data) info and a graph of the signal value over a 1 minute
period. This information is useful in verifying proper operation of the instrument.
The bottom box provides access to system settings that can be changed for diagnostics purposes.
Current software version is displayed in the lower right corner.
