Powering your equipment:
Open up the battery compartment using the supplied screwdriver. Correctly insert two AA
alkaline or rechargeable batteries. The remaining battery level is displayed in the right hand top
corner
.
A full green battery in the right hand top corner means that the battery is fully charged. The
equipment’s autonomy when fully charged will be around 7 hours.
The device can be powered through its USB port
with an external battery pack. Important:
The HATCHecker turns off automatically when the battery power is insufficient to ensure proper
operation, or after 10 minutes of inactivity.
Connecting the flexible sensor:
Connect the cable of the flexible sensor to the device by lining up the red dot on the plug with
the red mark on the connector
and then inserting the plug into the connector. To unplug
them, move-up the knurled barrel of the plug without any rotating movement. Proceed in the
same way to connect and unplug the cable on the side of the flexible extension. The ‘
ID’
and ‘Sensor ?’ messages
indicate that no or an incompatible sensor is connected. The “x”-
“sensor” indication will only disappear when the Hatchecker is correctly wired up and connected
to the correct flexible sensor.
Using the Hatchecker:
When pressing the on/off switch
, the equipment will switch on immediately.
To switch off, the on/off button needs to be pressed for approx.. 2 seconds.
To take a correct measurement, the amplification needs to be adjusted for every reading. This is
done by using the up and down arrows
and following the triangular amplification guidance
icons
in the top left hand corner of the display.
The current amplification setting is displayed here
.
Once the correct amplification level is reached, the reading (measurement) will be displayed in
green and a “smiley”
J
will appear in the place where previously the triangular amplification
guidance icon was shown. When the reading (measurement) is displayed in red, the
amplification is too high and will need to be reduced by pressing the “arrow down” button.
When ‘’-.-‘’ is displayed on the screen, the amplification is too low and will require increasing by
pressing the “arrow up” button. In both cases, i.e. when the amplification is too low or too high,
the amplification should be adjusted until the reading(measurement) is displayed in green and
the smiley
J
appears in the left hand top corner.
To ensure and confirm that the selected amplification level is correct, the operator can make
the sum of the amplification (shown in eth right hand lower corner
) and the reading
(measurement) on the display
, the result of which must be between 60 and 80.
Using the headphones:
To enhance the hearing experience, the audio volume of the headset can be adjusted by
pressing the left and right arrows
until the sound level is comfortable. Avoid setting the
sound too low as otherwise some signals may not be heard and possible leaky spots overlooked.
Connect the headphones here
.
The current volume setting is displayed
only when a headset is connected.
Reporting:
In order to facilitate recording of the readings (measures) taken during the survey, and reporting
after the survey is completed, SDT has developed the Sherlog HATCHReporter App.
