USER MANUAL
Ver 3 | 05/19

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 o automatically when the battery power is insucient to ensure proper
operation, or after 10 minutes of inactivity.
Connecting the exible sensor:
Connect the cable of the exible 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 exible 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 exible sensor.
Using the Hatchecker:
When pressing the on/o switch , the equipment will switch on immediately.
To switch o, the on/o button needs to be pressed for approx.. 2 seconds.
To take a correct measurement, the amplication needs to be adjusted for every reading. This is
done by using the up and down arrows and following the triangular amplication guidance
icons in the top left hand corner of the display.
The current amplication setting is displayed here .
Once the correct amplication level is reached, the reading (measurement) will be displayed in
green and a“smiley” Jwill appear in the place where previously the triangular amplication
guidance icon was shown. When the reading (measurement) is displayed in red, the
amplication is too high and will need to be reduced by pressing the“arrow down” button.
When‘’-.-‘’ is displayed on the screen, the amplication is too low and will require increasing by
pressing the“arrow up”button. In both cases, i.e. when the amplication is too low or too high,
the amplication should be adjusted until the reading(measurement) is displayed in green and
the smiley Jappears in the left hand top corner.
To ensure and conrm that the selected amplication level is correct, the operator can make
the sum of the amplication (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.
