Cautions On Operation; Instructions For Connecting To; The Measuring Unit - Sony LT10 Series Manual

• When providing DC power via the LT10/LT11's terminals,
or when using an AC adapter, be sure to use within the
specified voltage.
• Do not use connection prohibited terminal pins as relay pins.
• When connecting the BCD connector, be sure to wire the
connector correctly.
Failure to do so may damage the internal circuits.
• Place the display unit more than 0.5 m (20") away from a
high voltage source, large current source, large power
relay, etc.
• For installation of the display unit, avoid a location
exposed to chips, cutting oil, or machine oil. If
unavoidable, take adequate countermeasures.
• Do not put a vinyl cover directly over the display unit or
put it in a closed container.
• The ambient temperature should be in the range of 0 °C
to 40 °C (32 °F to 104 °F). Avoid exposure to direct
sunlight, hot air currents, or heated air.

1-3. Cautions on operation

Carry out the key operations or I/O (BCD, etc.) connections
and operations in line with the explanations given in the
appropriate sections. Failure to correctly operate this
device may result in a malfunction.

1-4. Instructions for connecting to

the measuring unit

• The LT10/LT11 is a display unit specifically designed for
the DT series measuring probe.
• When the LT10/LT11 is connected to a DT series and
turned on, the digits corresponding to the channel
connected may flash. This shows that initialization is
required to calibrate the new pairing of both device and
probe. Here you should move the measuring probe at
least 1 mm, as shown in the figure, and then press the
reset key on the LT10/LT11 corresponding to the
channel. The device will now return to its normal
measuring state.
Note
Once this procedure has been carried out the digits will not
flash while the device is connected to that measuring
probe, even if the power is turned off.
