Output Operation Mode

• 

The below describes based on OUT1. 

• 

OUT1 and OUT2 of output operations are same. It operates individually by the set output 
operation mode. 

 

GO output turns ON when the OUT1 and OUT2 turn OFF at the same time. (NPN / PNP open 
collector output type model)

• 

When changing output operation mode, high-limit / low-limit output setting value, hysteresis

 

are reset

and returns to run mode

Reset within the zero range. 

 01)  Displays at DC input model only.

Reset

01. 

Press the [◀] + [▲] + [▼] keys for over 5 sec. in run mode, INIT and NO flash 

alternately for 0.5 sec in turn. 

02. 

Change the setting value as YES by pressing the direction keys.

03. 

Press the [MODE] key to reset all parameter values as default and to return 

to run mode. 

Function Description

  

■ Display method: 

frequency

It measures input signal frequency when it is AC input.

In order to measure frequency normally, input signal, over 10 % F.S. of the rated input range, 

should be supplied.

Otherwise, it may not be measured normally.

The measurement range differs depending on the decimal point position.

It is available to adjust the high-limit display value gradient correction and exponent of INB at 

parameter setting.

• 

Accuracy of frequency measurement:  below 1 kHz, F.S. ± 0.1 % rdg ± 2-digit, 

 

from 1 k to 10 kHz, F.S. ± 0.3 % rdg ± 2-digit

  

■ High-limit display value gradient correction

This function is to correct a gradient of High / Low-limit scale value.

And also can be used as correction function of high-limit scale value. 

Adjustment range is setting value and multiply current gradient.
•  E.g.: To display 3.000 when 200 mVDC for input range 0-1 VDC

1.  Select input range = 1, decimal point position = 0.000 for measurement input in Parameter 1.

2.  It has to be 15.000 at high-limit scale for 1 VDCᜡ in order to display 3.000 for 200 mVDCᜡ. 

 

But if is disable due to setting range is 9.999.

3.  In this case, please set as high-limit display value gradient correction × high-limit scale = 

15.000.

  

■ High / Low-limit scale value

This function is to display setting of particular High / Low-limit value in order to display High / 

Low-limit 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. 

• 

When changing input range, it is changed automatically as factory default display range of 

the input range.

Zero adjustment

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.

 

1. Direct input correction value at Low-limit display value deviation correction parameter.

2.  Set the keys for zero adjustment parameter to YES and press the [◀] + [▲] keys for 3 sec in 

RUN mode.

3.  Set the external input terminal parameter to ZERO and short the Hold / Zero terminal for 

over 50 ms.

  

Error correction

It corrects display value error of measured input.

Display value =  (Measured value × High-limit display value gradient correction) 

 

+ Low-limit display value deviation correction

•  E.g.: When the Input range 0 to 500 VDCᜡ and the display range is 0 to 500.0
If the low-limit display value is 1.2 to 0 VDCᜡ input, set -12 as deviation correction value to 

display 0.0 by adjusting offset of the low-limit display  value.

The display value to 500 VDCᜡ measured input varies by adjusting the offset of low-limit 

display 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 High-limit display value gradient correction parameter 

to display 500.0 by adjusting gradient of high-limit value.

  

■ Startup compensation time

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.

  

■ Display cycle

In some applications the measured input may fluctuate which in turn causes the display to 

fluctuate. 

By adjusting the display cycle delay function time the operator can adjust the display time. 

For example, if the operator sets the display cycle time to 4 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.

  

■ Max. / Min. peak value

It monitors max./min. peak value of display value based on the current displays value and then 

displays the data at the parameters. 

When pressing any one of front keys at the parameters, the monitored data is initialized.

Set the delay time at peak monitoring delay time parameter in order to prevent malfunction 

caused by initial overcurrent or overvoltage, when monitoring the peak value.
