obtained from using the standard drop-height so any correlation with other outputs or test properties will need to be re-
determined or recalculated.
The accelerometer generates a signal regardless of any other electronics or power supply; it is always “on” detecting
vibrations. Protect the hammer from extreme shock even when the Control Unit is not switched on or connected. Do not
drop the hammer directly on concrete.
EACH HAMMER AND CONTROL ARE CALIBRATED AS A SET
Do not swap out either the hammer or control unit. Mismatching of these parts will give inaccurate results.
NEVER PLACE HANDS OR FEET IN OR UNDER THE GUIDE TUBE
The hammer is made to move freely inside the guide tube and injury is possible if hands or feet are placed in the path of the
hammer. Use special attention when lifting the Clegg as the hammer can slide.
Control: Power
To power on control unit, toggle the power switch to the ON position where illuminated side of
switch is depressed against the panel.
When control unit is powered on, the Power LED will flash to show the device is in an unconnected
state. At this time, the unit is able to be paired/connected to the tablet. The control unit is paired
via the Clegg Control app (available Google Play store). When the device is in a connected state, the
Power LED will stay lit continuously.
If the device is left in an unconnected state for a period of 10 minutes, it will automatically shut
down. In order to power on the device on after an automatic shutdown, do either of the following:
• Plug the device in to charge
• Toggle the power switch OFF, then back ON
BATTERY
The Control Unit contains a rechargeable battery. Recharge the battery using the included charging cable. The Clegg Control
app additionally displays a battery icon to denote the charge of the Control Unit. Do not replace the battery. A mismatch in
battery type can cause incorrect results or damage to the electronics and charger. Unauthorized disassembly will void any
warranty. Call Turf-Tec International if battery replacement is needed.
Control unit can be charged by either a computer’s USB port or with the supplied wall adapter. Charging via the supplied
wall adapter results in a faster charge rate. While unit is charging, the charge LED with be illuminated red. Once charging
has completed, the LED will shut off.
Control: Hammer Connection
Use the supplied BNC coaxial cable to connect the hammer to the control unit. To connect a BNC plug to socket, line up
the slots of the plug with the pins on the socket. Press the plug on and turn the plug clockwise until it locks. (Reverse steps
to remove plug) For the 10 kg model, connect the BNC end with the right-angle connector to the handle.
