## (mi **Functions** 

## **AC frequency measurement** 

## **[PA 1 group:** 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 [ **PA 1** : INbH ]and [ **PA 1** : INbE ]. In order to measure frequency normally, input signal, over 10% F.S. of the measured range, should be supplied. Please select the proper point of 

## ① Measuring range 

|Decimal point<br>position|0.000|0.00|0.0|0|
|---|---|---|---|---|
|Measurement<br>range|0.100 to<br>9.999Hz|0.10 to<br>99.99Hz|0.1 to<br>999.9Hz|1 to<br>9999Hz|



※Accuracy of frequency measurement: Below 1kHz, F.S. ±0.1rdg ±2-digit. From 1kHz to 10kHz, F.S. ±0.3rdg ±2-digit. 

② INbH : 0.100 to 9.999 [Gradient adjustment of high value] ③ INbE: 10-2, 10-1, 100, 101 [Index adjustment of INbH ] 

## **Zero adjustment** 

## **[Deviation correction function of low limit display value]** 

It adjusts the display 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 at saved in INbL automatically.

## **Transmission (DC4-20mA) output scale [PA2 group: / ]** 

It sets transmission output for the display value at the output current DC4-20mA. 

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% 

※When min. set interval between FS-H and FS-L is set 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-L and 20mA at over FS-H .

## **MT4Y/MT4W Series** 

## **Initialization** 

It initializes as the factory default status. If press , , keys together for 2 sec in **RUN** mode, INlT mode and the setting value ( NO ) is displayed every 0.5 sec and it will be initialized as the factory default when press MODE  key after change NO → YES . 

## **Startup compensation time** 

## **[PA 2 group:** 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 applied. Setting range: 00.0 to 99.9 (unit: sec) Factory default: 00.0 

## **Error display** 

|Display|Description|
|---|---|
|HHHH<br> <br>|Flashes when measuring input is exceeded the max.<br>allowable input(110%)|
|LLLL<br> <br>|Flashes when measuring input is exceeded the max.<br>allowable input(-10%)|
|D-HH<br> <br>|Flashes when display input is exceeded the max.<br>displayrange(9999)|
|D-LL<br> <br>|Flashes when display input is exceeded the min.<br>displayrange(-1999)|
|F-HH<br> <br>|Flashes when measuring frequency is exceeded the max.<br>measuringvalue(9999)|
|OVER<br>|Flashes when it exceeds zero adjustment range(±99)|



- ※Error display is released automatically when it is in the measured and display range. 

- ※" LLLL " is displayed when the measuring input is DC4-20mA. 

- ※ After flashing " OVER " 2 times when it exceeds the zero adjustment range, it returns to RUN mode. 

## **Display scale [PA 1 group:** H-SC **/** L-SC **]** 

This function is to display setting (-1999 to 9999) of particular High/Low-limit value in order to display High/Lowlimit value of measured input. If measured inputs are 'a' and 'b' and particular values are 'A' and 'B', it will display a=A, b=B as below graphs.

## **Gradient correction [PA 1 group:** INbH **]** 

This function is to correct a gradient of prescale value and display value. (Fig.1) Display value Y can be used as α, β times against X input value by correction function [ INbH ]. And also can be used as correction function of max. display value ( H-SC ). Adjustment range is 0.100 to 5.000 and multiply current gradient. E.g.) Input: DC200mV, Display: 3.000 for MT4W-DV

**Error correction [PA 1 group:** INbH **/** INbL **]** 

It corrects display value error of measured input. INbL[: ±99 [Adjust deviation of low value]] INbH[: 5.000 to 0.100 [Correct gradient (%) of high value]] Display value= (measured value × INbH ) + INbL E.g.) When 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 INbL value to display " )0 " by adjusting offset of the low value. The display value to 500V measured input varies by adjusting the offset of low value. If this display value is " 501.0 ", calculate 500.0/501.0 (desired display value/the display value), and set the 0.998 correction value as the INbH to display 50)0 by adjusting gradient of high value. 

※The offset correction range of INbL is within -99 to 99 for D-0, D-1 digit regardless of decimal point. 

## **Display cycle delay [PA 2 group:**[D1sT] **]** 

In some applications the measured input may fluctuate which in turn causes the display to fluctuate. By adjusting the display cycle delay function time in the D1sT 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 peak display value** 

## **[PA 0 group:** hPEK **/** lPEK **, PA 2 group:** PEkT **]** 

It monitors max./min. value of 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 PEkT of parameter 2 in order to prevent malfunction caused by initial overcurrent or overvoltage, 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 

keys at hPEK , lPEK of parameter 0, the monitored data is initialized. 

- ※ hPEK **,** lPEK parameters is not displayed when monitoring delay time [ PEkT ] of parameter 2 group is set as 00 sec [ 00 S ]. 

## **Preset output operation mode**

- ※"H" means hysteresis and able to set 1 to 99 at " HYS " mode in **PA 2** among above comparison output chart. 

- ※ hSET is displayed according to the setting of output operation mode, when user sets " OFF ", hSET / lSET are not displayed. 

- ※Only lST setting is available in MT4Y-☐-43 and MT4Y-☐-44 models. 

## **Sub output** 

- RS485 communication output 

- It is able to set address (01 to 99) 

- It is able to transmit by selecting modulation speed (transmitted number of signal per 1 sec) of serial trans -mission. (selectable 1200, 2400, 4800, 9600bps) 

- Low-speed serial output 

- It outputs current display value as Low-frequency (50Hz) type. 

- Transmission (DC4-20mA) output It outputs DC4-20mA against High/Low-limit scale. (resolution: 12000 division) 

- BCD dynamic output 

- It outputs display value as BCD Code. 

- ※ **Only one sub-output is selectable.** 

**(More than one sub-output is not allowed.)** 

## **Time chart of BCD dynamic output and Serial output** 

- BCD dynamic output (negative logic)
