Measuring Mode Operation
When the GX-3R Pro completes its startup sequence, it is in Measuring Mode. In Measuring
Mode the GX-3R Pro continuously monitors the sampled atmosphere and displays the target gas
concentrations. The GX-3R Pro is considered to be in Normal Operation if there are no alarm
indications.
Heart Symbol: The heart symbol in the upper left corner of the LCD indicates the operation status
and blinks when normal. A microprocessor error causes the heart symbol to stop flashing or to
disappear.
Check Mark: If
BUMP REMINDER
is set to
ON
and if a bump test is not due, a check mark
appears in the upper left corner of the LCD.
“S”: If the instrument is operating in Stealth Mode, an “S” appears at the top of the LCD.
Buzzer Icon: The buzzer icon indicates the buzzer volume. Lines in front of the icon indicate a
high buzzer volume. No lines in front of the icon indicates a low buzzer volume.
Bluetooth Icon: The Bluetooth icon flashes when the instrument is trying to pair to a phone. The
Bluetooth icon is steadily on when the instrument is paired to a phone. The Bluetooth icon is off
when the instrument is not paired and is not trying to pair to a phone.
Backlight: In a low-light environment, press and release either button to turn on the display
backlight. See page 109 to set the backlight time.
Confirmation/Non-Compliance Indicator: If the
BEEP
menu item in User Mode is set to anything
other than
OFF
, the GX-3R Pro gives periodic indications to confirm that it’s operating or to
indicate a non-compliance (see page 106 for instructions).
