2.3 Precautions for use

The hammer unit is precision measuring equipment. It is not a real “hammer.” Please
handle it with care. The instrument is made for concrete testing. Do not use it to hammer
nails or other “hammering” uses. It may lead to damages to the sensor.

The hammer-side of the hammerhead is used for making contact. The hammerhead will
eventually flaw the surface after many hits. If the flaws are not major, however, it will
have no effect on the measurements. Usually it is enough to use light impact force. Do
not hammer too strong. It may lead to damages to the sensor.

The opposite side of the hammer-side is the safety cap (yellow-colored plastics) of the
sensor. Do not use the cap side to make contact. It may lead to damages to the sensor.

The CTS-02V4 is not waterproof or water resistant. Please do not use it during rainfall or
areas of extreme high humidity. It may lead to damages to the instrument.

When hammering, please use while lightly holding onto the grip. The instrument cannot
produce accurate results if hammered while holding the shaft or hammerhead.

Please contact at a right angle when hammering the concrete. Diagonally hammering the
concrete will not produce accurate results. There is no problem if hammering within 10

from the right angle.

The possible measurement time of CTS-02V4 is approximately twelve (12) hours. This
possible measurement time is affected by the brands and types of batteries or the climate
that it is used. If using the instrument for an extended period of time, please prepare
spare batteries.

Do not energize over DC6V for the power supply. It will lead damages of the electronic
circuit.

Do not bend or pull the cable connecting with the hammer and the measurement
instrument. It may cause cable disconnection or short-circuit.
