Prescale Function [PA1 : H-SC/L-SC]
This function is to display setting (-1999 to 9999) of particular High/Low-limit value in order to display High/Low-limit value of measured input.If measured inputs are ‘a’ or ‘b’ and particular values are ‘A’ or ‘B’, it will display a=A, b=B as below graph.
Error Display Function
Error display is released automatically when it is in the measured and display range.‘LLLL’ is displayed when the input specification is DC.After flashing ‘OVER’ 2 times when it exceeds the zero range, it returns to RUN mode.
The above specifications are subject to change and some models may be discontinued without notice.Be sure to follow cautions written in the instruction manual and the technical descriptions (catalog, homepage).

Measurement Input [PA 1: IN-R]
Display Cycle Delay Function [PA 2 : DIsT]
In some applications the measured input may fluctuate which in turn causes the display to fluctuate.By adjusting the display cycle delay function time at DIS.T of parameter 2, the operator can adjust the display time within a range of 0.1 sec to 5 sec. For example, if the operator sets the display cycle time to 4.0 sec, the display value displayed will be the average input value over 4 sec and also will show any changes if any every 4 sec.
Monitoring Max./Min.Display Value Function[PA 0: hPEK/lPEK,PA 2: PEkT]
It monitors Max./Min. display value based on the current displays value and then displays the data at hPEK, lPEK of parameter 0. Set the delay time (0 to 30 sec) at PEkTof parameter 2 in order to prevent malfunction caused by initial over current or over voltage, when monitoring the peak value. Delay time is 0 to 30 sec and it starts to monitor the peak value after the set time. When pressing any one of 
key at hPEK, lPEK of parameter 0, the monitored data is initialized.Monitoring function is not displayed when the delay time is set as “00 S” at PEkT of parameter 2.
Initialization Function
This function is to initialize parameter as factory difault.
Current Output (DC4-20mA) Scale adjustment function [PA 2 : FS-H/ FS-L]
output DC 4-20mA.It sets display value for 4mA at FS-L and 20mA at FS-H and the range between FS-H and FS-L should be 10% F.S. (When it sets as under 10% F.S., it changed as over 10% F.S. automatically.) Preset display value is fixed to output as 4mA at under FS-Land 20mA at over FS-H.
AC Frequency Measurement Function [PA1 : DISP]
It measures input signal frequency when it is AC input.It uses fixed decimal point[PA1:DOT], measured range can be changed by setting and measured range of decimal point position is as below chart.It is available to adjust the upper gradient at [PA1:INbH] and [PA1:INbE]. In order to measure frequency normally, input signal, over 10% F.S. of measured range should be supplied. Please select the proper point of measurement terminal.
- Measured rangeAccuracy of frequency measurement: Below 1kHz, F.S.±0.1rdg ±2digit. From 1kHz to 10kHz, F.S ±0.3rdg ±2digit.
- INB.H : 00.100 to 9.999 [Gradient adjustment of high value]
- INB.E : 10-2, 10-1, 10-0, 101 [Index adjustment of INB.H]
Accuracy of frequency measurement: Below 1kHz, F.S.±0.1rdg ±2digit. From 1kHz to 10kHz, F.S ±0.3rdg ±2digit.Error Correction Function [PA 1 : INbH/ INbL]
It corrects display value error of measured input.INB.L: ±99 [Adjust deviation of low value]INB.H: 5.000 to 0.100 [Correct gradient (%) of high value]Diplay value= (Measured value × INB.H) + INB.LWhen the measured range is 0 to 500V, and the display range is 0 to 500.0. If the low display value is “1.2” to 0V input, set -12 as the INbL value to display “0.0” by adjusting the offset of the low value.The display value to the 500V measured input varies by adjusting the offset of the low value. If this display value is “501.0”, calculate 500.0/501.0 (the desired display value/the display value), and set the 0.998 correction value as the INbH to display “500.0” by adjusting the gradient of the high value.The offset correction range of INbLis within -99 to 99 for D-0, D-1 digit regardless of dicimal point.
Zero Adjustment Function
It adjusts the indication value of the optional configured input value as zero by force, zero point error can be adjusted with 3 ways as below.When zero point adjustment with front key and Hold terminal is finished normally, zero point of measurement terminal is displayed and the adjusted value is saved at INbL automatically.
Refer to description “
Error Correction Function” ” ErrorDisplay Function”, ” Parameter 2″ for function and error.
Gradient Correction Function [PA 1 : INbH]
It corrects the gradient of prescale value and display value. (Picture 1) Display value Y can be used as α, β times against X input value by correction function[ INbH] and used as correction function of max. display value[ H-SC].Adjustment range is 0.100 to 5.000 and multiply current gradient.
Ex)Input:200mVDCᜡ, Display:3.000 for MT4W-DV type
- Select 0-1VDCᜡ (1V) for measured input in Parameter 1.
- Standard specification in input: 0-1VDCᜡ and 1.000 therefore it has to be 15.000[ H-SC] for 1VDCᜡ (Input) in order to display 3.000 for 200mVDCᜡ (Input).But it is unable due to setting range is 9.999
- In this case, please check below chart.Please set as INbH× H-SC = 15.000
Preset Output Mode [PA 2 : OUtT]
hSETis displayed according to the setting of output operation mode, when user sets “OFF”, hSET/ lSETare not displayed.
Startup Compensation Timer Function[PA 2 : STaT]
This time function limits the operation of an output until the measured input (overvoltage or inrush current) is stable at moment of power on. All outputs are off during startup compensation time setting after power is supplied.Setting range: 00.0 to 99.9 (unit: sec), Factory default: 00.0
