■ AUTOMATIC ZERO CORRECTION

Set the offset input value. Perform automatic zero correction setting after Zero/Span adjustments.

The procedures are as follows.

1) Apply desired offset input value to the sensor.

2) Set “1” to Automatic zero correction bit. When the offset is completed, LED0 for Input 0 or LED8 for Input 1 turns on.

3) After checking the LED, set “0” to Automatic zero correction bit.

■ ZERO ADJUSTMENT

Adjust input zero point. The procedures are as follows.

1) Apply 0% load to the sensor.

2) Set “1” to Zero adjustment bit. When the adjustment is completed, LED1 for Input 0 or LED9 for Input 1 turns on.

3) After checking the LED, set “0” to Zero adjustment bit.

■ SPAN ADJUSTMENT (with actual load)

Adjust input span point with the actual load. The procedures are as follows.

1) Apply actual 100% load to the sensor.

2) Set “1” to Span adjustment bit. When the adjustment is completed, LED2 for Input 0 or LED10 for Input 1 turns on.

3) After checking the LED, set “0” to Span adjustment bit.

■ LOAD COEFFICIENT

Adjust input Span point by setting load coefficient without applying 100% actual load. The followings are an example of

adjustment with 20 % load.

1) Apply 20% load of the actual load to the sensor.

2) Set 2000 (decimal) to Input set data area.

3) Set “1” to Span adjustment bit. When the adjustment is completed, LED2 for Input 0 or LED10 for Input 1 turns on.

4) After checking the LED, set “0” to Span adjustment bit.

■ MODE SETTING

Select measuring mode or monitor output mode.

• Measuring mode

Set “0” to Mode setting bit to enter measuring mode. In measuring mode, monitor output is linked with input data.

• Monitor output mode

Set “1” to Mode setting bit to enter monitor output mode. In monitor output mode, values at set data area of each input

are outputted. Set values at set data area are displayed in Input data area and inputs are disabled. The followings are

setting procedures of 20% monitor output for Input 1.

1) Set 2000 (decimal) to Input 1 set data area.

2) Set “1” to Mode setting bit. When the setting is completed, LED7 turns on and 20% of Input 1 is outputted from

monitor output terminal .

3) After checking the output, set “0” to Mode setting bit to return to measuring mode.

■ RESET OFFSET

Reset the offset value set by Automatic zero correction to zero. The procedures are as follows.

1) Set “1” to Reset offset bit. When the reset is completed, LED4 for Input 0 or LED12 for Input 1 turns on.

2) After checking the LED, set “0” to Reset offset bit.

“1” is to be set when input is -1.0% or less.

■ INPUT BELOW RANGE (Input only)

“1” is to be set when input is within the range between -1.0% and 101.0%.

“1” is to be set when input is 101.0% or more.

■ INPUT OVER RANGE (Input only)

■ INPUT WITHIN RANGE (Input only)
