NOTE
●The power line and input/output signal lines should
be installed away from noise-generating sources.
Otherwise accuracy cannot be guaranteed.
●The wiring resistance of input terminals and
should be the same.
●Adhere strictly to the specifications to avoid
overheating or damage. Before turning on the power,
ensure the following:
(a) Power supply voltage and input signal value
applied to the product should meet the required
specifications.
(b) The external wiring to the terminals and wiring to
ground are as specifications.
●Do not operate the product in the presence of
flammable or explosive gases or vapors.
●The product is sensitive to static electricity; exercise
care when in operation. Before you operate the
product, touch a nearby metal part to discharge
static electricity.

Setting Temperature Unit
Set the temperature unit of the input range in [B09: UNIT]
NOTE
Do not set the "-----" as the temperature unit, even if it
is displayed during the setting.
Otherwise it may cause the malfunction or damage.
Setting Input Range
Set the zero percent value of input range in [B0: ZERO], and
the span of input range in [B: SPAN].
Setting Burnout Action
Set the burnout action in [B2: BURN OUT]
Set "OFF", "UP", or "DOWN."
NOTE
Input adjustment should be applied when the setting
of input range, burnout action direction or input wiring
has been changed.
