POWER ON:
Turn on or off by long pressing the
ON/OFF button. The power LED will illuminate
green unless battery is low.
WARM-UP:
During warm-up, the unit will
beep slowly and the signal LEDs will continu-
ously scroll from left to right until warm-up is
complete. Warm-up time is 45 to 90 seconds.
SEARCH:
Detector is ready for use when
signal LEDs stop scrolling from left to right and
a different beep rate can be heard.
If a leak is detected, the signal LEDs will
illuminate from left to right and the beep rate
will increase. The number of LEDs illuminated
indicates the strength of the leak.
The default mode is Standard mode. In
Standard mode, the detector automatically
zeros to the background refrigerant. Once it
zeros, the alarm will stop and it will only alarm
to a higher concentration of refrigerant. To
reset the zero point, hold the probe in clean
air for a few seconds to allow the detector to
re-zero.
ADJUSTING THE SENSITIVITY LEVELS:
Short
press the ON/OFF button to toggle sensitivity
from high to low. The HIGH or LOW LED will
illuminate to indicate the current sensitivity
setting. High is the default setting during
power on.
MANUAL MODE:
Short pressing the MODE
button toggles between Standard mode and
Manual mode. Manual mode is indicated by
the 1st signal LED slow blinking and both HIGH
and LOW LEDs being off.
In manual mode, if a leak is detected, the
detector will alarm until the MODE button is
long pressed. The HIGH and LOW LEDs will
blink for 1 second to indicate the detector is
zeroing. At this point, the detector will only
alarm if a high concentration of refrigerant is
detected.
OPERATING INSTRUCTIONS
2
You can also reset the zero point in clean air
by holding the detector in clean air and long
pressing the MODE button again.
BATTERY AND CHARGING:
The power LED
will slow blink red when the battery is 10%
or less. If the battery is depleted completely,
the power LED will illuminate solid red and the
unit will not operate.
To charge the unit, plug the supplied micro
USB cable into an appropriate USB charging
port per the input specifications (see specifi-
cations).
When charging, the power LED will slow blink
green until fully charged, then remain solid
green.
ERRORS:
If the battery is above or below
charge temperature, the unit will not charge
and the power LED will alternate red and
green. In this case, let the battery cool or
warm up. The unit will charge once the
battery is within the safe operating tempera-
ture.
Other faults or internal errors are indicated
when all LEDs blink. Contact Ritchie Engineer-
ing Company, Inc. for service in this case.
