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.
Operating humidity: 0 to 95 %RH (non-condensing)
Weight: 65 g (2.3 oz)

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.
