Leak Testing
The increment of the reading is always 10 ppm but the display range
can be adjusted by using the DISPLAY (ADJ) button. The display
range choices are 1000 ppm, 2000 ppm, 4000 ppm, and 9990 ppm. The
readings are displayed in both numerical and bar graph form. As the
gas concentration increases from 0 ppm, the alarm LEDs begin to
blink in unison with the buzzer’s pulsing. The blinking/pulsing rate
increases as the gas reading increases. If desired the buzzer can be
turned off in Leak Check Mode.
In a low-light environment, press and release any of the buttons to
turn on the display backlight. See “Updating the LCD Back Light
Time Setting” on page 77 to program backlight duration. If BEEP. SET
is turned on in Maintenance Mode, the Gas Tracer beeps once every 5
minutes to confirm that it’s operating.
