(3) Applicable environment
Warning: The instrument may subject to use in a highly humid area or in full of powder dust, In such a
case, use the instrument by inserting the panel mount gasket attached between the control panel
(cabinet) and the main body.
By inserting the panel mount gasket, the front panel section becomes IP65 (International Protection
Code) or equivalent in dust-proof and water-proof construction.

2. Power supply
Warning
Be sure to check that power supply is OFF when installing each cable. If an operator works with power ON,
he/she may have an electric shock or the instrument may be destroyed.
Warning
Be sure to ground a grounding wire. If a grounding wire is not grounded, it may cause malfunction of the
instrument or an electric shock to an operator.
Caution
Before supplying power, check the indication of power voltage/specifications to be identical with supplied power.
If they are not identical, contact with us Without checking the above, operation may cause damage to the
instrument or electric shock
3. Instructions for use
Caution
Before using a new instrument, or when exchanging a strain gage applied transducer for a new one, be sure to
make calibration. If neglected, it may cause incorrect results in measurement or malfunction in the instrument and
moreover may cause damage to peripheral equipments. When similar trouble occurs after calibration, be sure to
make calibration again, even if calibration has completed.
Caution
When using the instrument, check that wires are connected properly. If neglected, correct measurement cannot
be obtained and it may cause malfunction in the instrument or cause damage to peripheral devices or a critical
accident.
Caution
Improper change of setting during operation may cause incorrect measurement or malfunction, or cause damage
to peripheral equipments.
Caution
Do not give the instrument such a shock as throwing something at it. It may cause damage or destroy electrical
circuits and even have loose resistance to environment or operability.
When in the shipment, there is a clear sheet for protecting on the panel. Remove the clear sheet before use the
instrument.
Never push the panel sheet of the instrument with strong force more than necessity is required, or push it with s
sharp end of the driver or rap it. The touch panel will have damage and have the possibility of resistance to
environment or operability.
