PERFORMANCE

Accuracy: ±0.01 mA

Temp. coefficient: ±0.015 %/°C (±0.008 %/°F) at 4 – 20 mA

input

HOW TO CALCULATE ACCURACY AGAINST SCALE

Example 1: 4 – 20 mA input, Scale 0 – 100

Accuracy = 0.01 mA ÷ (20 – 4)mA × 100 = 0.063 %

Display Error = (100 – 0) × 0.063 % = ±0.063 digits

Example 2: 10 – 20 mA input, Scale 100 – 1000

Accuracy = 0.01 mA ÷ (20 – 10)mA × 100 = 0.1 %

Display Error = (1000 – 100) × 0.1 % = ±0.9 digits

DISPLAY DESCRIPTIONS

■ DISPLAY DIGITS

The decimal point position may shift according to the

required number of digits for the integer section, even when

more than one decimal places have been specified.

However, when the number of decimal places is set to 3,

the ‘0’ in the integer section is not shown in order to secure

the number of effective digits, as explained in the table

below.

The ‘0’ is displayed when the number of decimal places is

set to 2, though the number of effective digits in this case is

reduced by 1 digit compared from the 3 decimal places.

Select appropriately for the application. Refer to

‘Programming Procedure’ for how to choose decimal point

positions.

■ ERROR INDICATION

The data display blinks when an abnormality is detected.

The unit display backlight also blinks.

When the setting error or the security code error occurs, press

ENTR / ESC button once to cancel the error status and proceed

to set again.
