DANGER

• The input/output terminals are subject to electric shock risk. Never let the input/ output terminals come in contact with your body or conductive substances.

WARNING

• This product does not contain an electric switch or fuse, so the user needs to install a separate electric switch or fuse externally.(Fuse rating: 250 V 0.5 A)
• To prevent defection or malfunction of this product, supply proper power voltage in accordance with the rating.
• To prevent electric shock or malfunction of product, do not supply the power until the wiring is completed.
• Since this product is not designed with explosion-protective structure, do not use it any place with flammable or explosive gas.
• Do not decompose, modify, revise or repair this product. This may be a cause of malfunction, electric shock or fire.
• Reassemble this product while the power is OFF. Otherwise, it may be a cause of malfunction or electric shock
• If you use the product with methods other than specified by the manufacturer, there may be bodily injuries or property damages.
• Due to the danger of electric shock, use this product installed onto a panel while an electric current is applied.

CAUTION

• The contents of this manual may be changed without prior notification.
• Before using the product you purchased, make sure that it is exactly what you ordered.
• Make sure that there is no damage or abnormality of the product during delivery.
• Do not use this product at any place with corrosive(especially noxious gas or ammonia) or flammable gas.
• Do not use this product at any place with direct vibration or impact.

Front-key functions and names

function mode
• In operation mode, when SV display window is in input range display mode, press key, H lamp is turned on and the SV display window is converted to the upper limit comparison value.
• In operation mode, when SV display window is in upper limit comparison value display mode, press key, L  lamp lights up and the SV display window is converted to the lower limit comparison value.
• In operation mode, when SV display window is in lower limit comparison value display mode,  press key, L  lamp goes out and the SV display window is converted to the input range value set in the parameter.
• If the model is not an output model or O－MD is OFF, the SV display window is fixed with the input range value set in the parameter.
SHIFT | • In the operation mode, when the SV display window is in the upper limit comparison value display mode, press the key to enter the upper limit comparison value setting mode.
• In operation mode, when SV display window is in the lower limit comparison value display mode,  press the key to enter the lower limit comparison value setting mode.
• Pressing the  key in the upper limit comparison value setting mode moves the digit of the upper limit comparison value.
• Pressing the  key in the lower limit comparison value setting mode moves the digit of the lower limit comparison value.
• The setting range of the upper limit comparison value and lower limit comparison value depends on the decimal point position set in the parameter. can be set as ‘9.999 ~－9.999 / 99.99 ~－ 99.99 / 999.9 ~－999.9 / 9999 ~－9999”
ZERO / DOWN | • Pressing the  key in the upper limit comparison value setting mode decreases the upper limit comparison value in the SV display window.
• Pressing the  key in the lower limit comparison value setting mode decreases the lower limit comparison value in the SV display window.
• In operation mode, key is pressed for more than 1 second, the current measured value is forcibly corrected and stored automatically in the parameter ZERO.(However, when parameter K－ZO is selected as ‘ON’)
• Pressing the  key in the maximum value display mode resets the maximum and minimum values.
• Pressing the  key in the minimum value display mode resets the maximum and minimum values.
PEAK / UP | • When the  key is pressed in the operation mode, the PV display window changes to the maximum value display mode.
• When the  key is pressed in the maximum value display mode, the PV display window changes to the minimum value display mode.
• key is pressed in the minimum value display mode, PV display window is converted to operation mode.
• Pressing the  key in the upper limit comparison value setting mode increases the upper limit comparison value of the SV display window.
• Pressing the  key in the lower limit comparison value setting mode increases the lower limit comparison value of the SV display window.
• If parameter D.TMR is ‘0’, there is no display conversion between PV display window’s maximum value display mode and minimum value display mode

Function mode

Function Mode Configuration

• The function mode consists of 4 parameter groups: P.FUN / P.EXP / P.OUT / P.OPT.
• P.FUN is a group of general function setting parameters.
• P.EXP is an extended function setting parameter group.
• P.OUT is a group of output function setting parameters related to the output model.
• P.OPT is a group of optional function setting parameters related to transmission output and communication output models.
• Press the key for more than 3 seconds in the operation mode to enter the function mode.
• In function mode, if key is pressed for more than 3 seconds, all parameter values are saved and operation mode is restored.
• FREQ is displayed only on AC models (when FREQ is selected, AC.TY / EX.IN / K－ZO is not displayed)
• AC.TY displayed on AC models only (AVG / RMS selected)
• P.OUT is displayed only on the output model (if O－MD is OFF, S.TMR / HYS is not displayed)
• P.OPT is displayed only in transmission output and communication output models
• PV.SH/PV.SL is displayed only in transmission output model
• S－NO / BPS / PTY / RWT / CWP are displayed only in communication output model
