ULTRAChecker

User manual
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 ULTRAChecker turns o automatically when the battery power is insucient to ensure
proper operation, or after 10 minutes of inactivity.
Connecting the sensor cable :
Connect the cable of the 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 ‘Sensor ?’ messages  indicate that no or an incompatible sensor is connected. The
“x”- “sensor” indication will only disappear when the ULTRAChecker is correctly wired up and
connected to the correct sensor.
Using the ULTRAChecker:
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ca-
tion 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ca-
tion should be adjusted until the reading(measurement) is displayed in green and the smiley J
appears in the left hand top corner.
Using the headphones:
To enhance the hearing experience, the audio volume of the headset can be adjusted by press-
ing 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.
