DISPLAY

LED: 8 mm (.3”) 7-segment, red
Number of display digits: 4
Scaling range: -1999 to 9999 counts
Offset range: -1999 to 9999 counts
Decimal point position: 10^-1, 10^-2, 10^-3 or none
Polarity sign: Minus (–) sign added automatically according to the computation result
Over-range warning: All segments dark except the top ones that blink with the input exceeding the display/measurable range; or the bottom ones that blink with the input below the range.
Read rate: 2.5/s
Engineering unit indication: Sticker label attached

INPUT SPECIFICATIONS

■ DC Current: 4 – 20 mA DC
Measurable range: 3.75 – 23 mA DC
Maximum input current: Refer to ‘Safety Parameters.’
Voltage drop: Approx. 3.7 V with 4 mA
Approx. 4.0 V with 20 mA (Equivalent input impedance: Approx. 200 Ω)
(The minimum required supply voltage to the 2-wire transmitter added with the indicator’s voltage drop at the maximum input current must be within the output voltage range of the 2-wire transmitter’s excitation supply.)

INSTALLATION

Operating temperature: Refer to the 'Safety Parameters' section.
Weight:
• Unit
Approx. 1.3 kg (2.9 lb), aluminium
Approx. 4.0 kg (8.8 lb), stainless steel
• Mounting bracket assembly (option)
Approx. 0.78 kg (1.72 lb)

PERFORMANCE

Accuracy: ±0.01 mA
Temp. coefficient: ±0.015 %/°C (±0.008 %/°F) at 4 – 20 mA input
Dielectric strength: 1500 V AC @ 1 minute
(input to outdoor enclosure)

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.
