Depending on circumstances, procedures indicated byserious consequences, so be sure to follow the directions for usage.
Procedures which may lead to dangerous conditions andcause death or serious injury, if not carried out properly.

WarningCautionProcedures which may lead to dangerous conditions andcause superficial to medium injury or physical damage or may
degrade or damage the product, if not carried out properly.

Warning

Caution• Do not leave wire remnants in the instrument, because they could cause afire or malfunction.
• When wiring, use a crimping pliers and a solderless terminal with aninsulation sleeve in which an M3 screw fits.
• Tighten the terminal screw using the specified torque.
• This instrument does not have a power switch, circuit breaker and fuse.
Therefore, it is necessary to install a power switch, circuit breaker and fuseexternally near the instrument.
(Recommended fuse: Time-lag fuse, rated voltage 250 V AC, rated current 2 A)
• Connect the AC power to the designated terminal as is written in thisinstruction manual. Otherwise, it may burn and damage the instrument.
• Do not apply a commercial power source to the sensor which is connected tothe input terminal nor allow the power source to come into contact with thesensor.
• Use a thermocouple and compensating lead wire according to the sensor
input specifications of this instrument.
• Use the 3-wire RTD according to the sensor input specifications of thisinstrument.
• When using direct current or DC voltage input, ensure polarity is correct.
• When wiring, keep Input/Output wires away from AC power sources.

‫ە‬Operation and Maintenance Precautions

Caution• Do not touch live terminals. This may cause an electrical shock or problems
in operation.
• Turn the power supply to the instrument OFF before retightening the terminalor cleaning. Working on or touching the terminal with the power switched ON
may result in severe injury or death due to electrical shock.
• Use a soft, dry cloth when cleaning the instrument.
(Alcohol based substances may tarnish or deface the unit.)• As the display section is vulnerable, be careful not to put pressure on,
scratch or strike it with a hard object.

applications, military equipment, etc.), please investigate the end users andthe final use of this instrument. In the case of resale, ensure that thisinstrument is not illegally exported.

‫ە‬Installation Precautions

CautionThis instrument is intended to be used under the following environmental
conditions (IEC61010-1): Overvoltage category , Pollution degree 2
Ensure the mounting location corresponds to the following conditions:• A minimum of dust, and an absence of corrosive gases• No flammable, explosive gases• No mechanical vibrations or shocks• No exposure to direct sunlight, an ambient temperature of -10 to 55(14 to 131 ) that does not change rapidly, and no icing• An ambient non-condensing humidity of 35 to 85 %RH• No large capacity electromagnetic switches or cables through which large
current is flowing• No water, oil, chemicals or the vapors of these substances can come into
direct contact with the unit
• Please note that the ambient temperature of this unit – not the ambient
temperature of the control panel – must not exceed 55 (131 ) if mounted
through the face of a control panel, otherwise the life of electroniccomponents (especially electrolytic capacitors) may be shortened.
Note: Avoid setting this instrument directly on or near flammable material
even though the case of this instrument is made of flame-resistant resin.

4. Adjustment
The output of this unit has been already adjusted before shipping. Therefore, it is
not required to adjust the unit in the case users use it with the ordered Input/Output
specification. However, in the case of fine adjustment or calibration between
connected units, adjust the value following the procedure described below.
Connect an mV generator or Dial resistor to the input terminals of this unit.
Connect a digital multimeter to the output terminals.
Adjust Output 1(1) Enter the value corresponding to 0% output, then adjust the value with the Output
1 Zero trimmer while viewing the output value (on the digital multimeter).
(2) Enter the value corresponding to 100% output, then adjust the value with theOutput 1 Span trimmer while viewing the output value (on the digital multimeter).
(3) Enter the value corresponding to 0% output again, and confirm the outputvalue (on the digital multimeter).
(4) If the value corresponding to 0% output is not at 0%, repeat steps (1) to (3) again.
Adjust Output 2 [For SG‫ڧ‬W (2-outputs spec)]
Procedure for Output 2 adjustment is the same as that of Output 1 adjustment.
Use the Output 2 Zero and Span trimmers for adjustment.
