4.0 DISPLAY MESSAGES AND PROMPTS
The display messages and prompts displayed by the meter are listed alphabetically within this section. Display messages
and prompts are shown within square brackets throughout the text in other sections of this Instruction Manual. An AirFoil
probe reading in MANUAL reading mode is shown as [FP ± nnnn].
Manual and automatic reading prompts and measurement displays have a battery symbol ( ) as the third or fourth character
of the display. This battery symbol indicates the level of charge in the batteries. This battery symbol is not generally shown
in the text throughout this manual.
If either the STORE or AUTO STORE mode has been selected, the read prompts and measurement displays have a letter
as the first character to the right of the reading sequence number. This letter represents the memory grouping and is not
generally shown in the text throughout this manual. Where it is shown in the manual, it is represented by the letter “G”.
An AirFoil probe reading in either STORE mode is shown as [nnG ± nnnn]. When the charge in the batteries begins to fail,
the letter representing the memory group will be replaced by the symbol for an empty battery.
If the TREND mode has been selected, the measurement displays have an arrow as the first character to the right of the
units abbreviation. When the charge in the batteries begins to fail, the message [LOCHARGE] will be displayed after every
30 readings displayed.
